What is the difference between a frequency converter and an AC power input DC brushless motor?
Q: That's right! I forgot again! Okay! Now I can go teach newcomers. Thank you! Ah~I don't know how to A the customer.
A: Huh? What's wrong?
Q: A customer said they want to use a frequency converter or DC brushless motor for speed control. I know about AC speed control motors, but I don't know which one is more suitable for speed control, a frequency converter or a DC brushless motor? So I don't know how to A the customer.
A: So that's how it is. First of all, it is necessary to understand the characteristics of the frequency converter and the DC brushless motor.
Q: What are the characteristics of the frequency converter?
A: By combining the frequency converter with a three-phase 220V AC motor and changing the power frequency, the speed can be controlled. When connecting, simply connect the power supply to the three-phase motor and perform simple speed control.
Q: Oh, it's really simple. However, I heard that setting up the frequency converter is very complicated, so is it still inconvenient?
A: For example, when using a frequency converter to control the voltage by adjusting the frequency, if the applied voltage at low speed is set to a low value, the motor speed may not produce torque at low speed.
Q: How about this! Does this mean that when preparing the motor and frequency converter separately, it is necessary to change the settings?
A: Yes. It's not that there's no need to change the settings. However, if it is our frequency converter combination, because the settings that can fully utilize the motor characteristics have already been set, customers can easily use it.
Q: So that's how it is. So if you want to do simple speed control, can you use a combination of frequency converters?
A: It's not like that. Don't worry. There are speed control motors and DC brushless motors, right? It can not only save energy and space, but also control speed with smooth torque. It is necessary to know their respective characteristics in order to introduce them to customers.
Q: Save energy? Save space? Steady torque?
A: So let's talk about saving space first. Strong permanent magnets are used in the rotor inside the motor. So not only can it have high power, but the motor can also be miniaturized, achieving the effect of saving space.
Q: Really! DC brushless motors are really small and thin in size.
A: Yes. So it can be very helpful for reducing the volume of the device.
Q: So that's how it is! But will a smaller size make it easier to generate heat?
A: I won't. DC brushless motors will perform current control and only flow the necessary current when necessary, so not only is it efficient, but it can also save energy.
Q: I see. And the speed of load changes is very small, so a certain torque can be maintained from low speed to high speed.
A: Yes. Are you also well aware of the advantages of DC brushless motors.
Q: Hmm. The combination of frequency converter and DC brushless motor each has its own advantages, and now I don't know which one to recommend to customers
A: This is simple. Just remember their respective characteristics and suggest using the most suitable product for the customer's device.
Q: I see. I need to reply to the customer quickly. Thank you very much.
Can you tell me the difference between using a stepper motor and an AC servo motor?
Q: Look, look, I received a customer's request for dependency!
A: Not bad, it seems that you are really working hard. Is the selection okay?!
Q: Well, the customer's purpose is for positioning control, so both stepper motors and servo motors should be usable. But which one should I choose? I'm worried about it
A: Which institution is the customer using it for? What is the operating mode?
Q: It is used for handling on pulley mechanisms. The amount of movement and positioning time required for each transportation is very short. In this case, should we choose servo motors that are good at high-speed operation?
A: No, no, it's better to use a stepper motor in this situation.
Q: Is that true? Why?
A: This is because the customer is using a "pulley mechanism"!. Compared with stepper motors, servo motors allow for smaller inertia, making them less suitable for use in mechanisms where the load inertia increases, and pulleys belong to this type of mechanism. When using a servo motor, it is necessary to adjust the responsiveness of the motor based on the magnitude of the load inertia, which is called "gain adjustment". But when used on mechanisms such as pulleys where the inertia of the load increases, the responsiveness cannot be improved.
Q: Is that so? But even for pulley mechanisms, as long as the workload is light, the inertia is also small, and it should be able to achieve a certain level of responsiveness!
A: Doesn't the belt of the pulley mechanism stretch and contract? Mechanisms with poor rigidity like this are prone to instability due to load inertia, making it difficult to make gain adjustments to improve responsiveness.
Q: So there are things that servo motors can't do
A: At this point, because the stepper motor can be easily used without gain adjustment, it is very convenient to assemble the equipment.
Q: I see
A: Also, isn't the operation mode requested by the customer this time very short in terms of movement and positioning time? Although servo motors are closed-loop controlled and can monitor their movements at any time, the required setting time for such control is reflected through the so-called "delay" phenomenon. And stepper motors operate synchronously based on pulse signals, so there is basically no "delay" phenomenon like servo motors.
Q: So, what if it's in the case of a long amount of movement?
A: When the movement is long, it is more advantageous to choose a servo motor with the highest speed. For example, it is more suitable to perform positioning operation with a large amount of movement on screw mechanisms with shorter lead. Due to the strong rigidity of the mechanism, the responsiveness can be improved through gain adjustment, thus fully utilizing the strengths of servo motors.
Q: So, when selecting, in addition to considering the characteristics of the motor itself, the rigidity and other structural features should also be taken into account, right?
A: Exactly so. When choosing a motor, the first thing to do is to master these key points. However, don't forget to accurately calculate the selection. Be sure to confirm whether the motor truly meets the action requirements required by the customer.
Q: Thank you, I understand now! Your "responsiveness" has always been so clear, no wonder there is no need for "gain adjustment".
A:?
Will the over rotation of the motor vary depending on the type of motor?
Q: I have a very basic Q to ask. Actually, I am not very familiar with the "over rotation" of motors .
A: Where is it?
Q: What I want to ask is, is the amount of rotation from cutting off the power to completely stopping the motor when I want it to stop called "over rotation"?
A: Yes. By the way, the larger the inertia of the load on the motor shaft, the greater the amount of over rotation.
Q: Huh? Does that mean there is a relationship between the rotational speed and the inertia of the load?
A: Yes, let's take the example of a truck with goods and a truck without goods! If the truck carrying goods stops urgently at the same speed, will the distance until it comes to a stop become longer! Similarly, the larger the inertia of the motor's load, the greater its over rotation.
Q: I see! So, what is the approximate amount of over rotation of a motor in general?
A: Depending on the type of motor, the amount of over rotation also varies. The over rotation of an induction motor under no-load conditions is approximately 30-40 revolutions.
Q: Will the amount of over rotation vary depending on the type of motor?
A: Yes. For reversible motors, the over rotation is only about 5-6 revolutions.
Q: Why is that? Why is the over rotation of reversible motors smaller than that of induction motors?
A: Isn't a reversible motor equipped with a simple brake for instantly switching the direction of motor rotation? So, compared to induction motors, the amount of over rotation will be much smaller.
Q: So that's how it is. So, what is' simple braking '?
A: There is a brake pad on the rotor of the motor, and the brake pad is pressed against this plate.
Q: Oh~So, over rotation refers to the number of rotations of the motor shaft? So, what about the amount of over rotation when using a gearbox?
A: That's a very good Q! The amount of over rotation is indeed reflected by the speed of the motor shaft. So, when using a reducer, the amount of over rotation of the output shaft is equal to the "1/reduction ratio" of the reducer.
Q: So, if a reducer with a reduction ratio of 1:3 is used on an induction motor, the amount of over rotation of the output shaft of the reducer is 10-13 revolutions, right?
A: Exactly so. The larger the reduction ratio of the gearbox, the smaller the amount of over rotation. However, due to the speed being 1/reduction ratio, the speed will slow down, which means that production efficiency will decrease. Therefore, customers must pay full attention to this point. If you want to reduce the amount of over rotation without changing the speed, you can use a motor with an electromagnetic brake or a brake.
Q: I know that! It refers to electromagnetic brake motors that can mechanically maintain the position of the motor and brakes that use brake current to instantly stop the motor!
A: Yes. The over rotation of the motor with electromagnetic brake is about 2-3 revolutions, while using the brake, it is only about 1-1.5 revolutions.
Q: I see. I didn't expect that from the perspective of over rotation, it can also be found that it is affected by the type of motor.
A: Therefore, when selecting a motor, it is necessary to distinguish it according to its intended use. In the future, when customers come for consultation, it is important to carefully confirm their usage conditions and introduce suitable motors to them. You must keep going!
Q: Okay! I will definitely try my best. Thank you!
Please advise me on effective methods for setting up fans!
Q: It's really cold! It's snowing outside. I'm the most afraid of the cold....
A: Actually, I'm also very afraid of the cold.... But in such cold weather, a customer just asked, "Although a cooling fan is used, the temperature inside the control panel is still very high. I really don't know what to do
A: If there are multiple drives in the control panel and appropriate heat dissipation measures are not taken. Even in winter, the temperature inside the controller may still be high. So what are the countermeasures?
Q: It may be due to insufficient air volume relative to the temperature rise inside the control panel, so I suggest the customer confirm the usage conditions and analyze whether the fan currently in use is suitable.
A: Not all of them! However, even if customers use fans with high air volume like the MRS series, if the setting method is incorrect, it may not be able to fully utilize the characteristics of the fan. Take the situation of this customer consultation as an example! The cooling method of exhausting the hot air inside the control panel to the outside is called "ventilation cooling". Do you know what issues to pay attention to in this situation?
Q: This... I don't know anymore.
A: Let me tell you, it's not just the motor, you also need to enrich your knowledge of fans! Firstly, since it is "ventilation", it means that there must be air inlets and outlets inside the control panel, namely the "intake port" and "exhaust port". This is actually the same principle as promoting room air convection. The focus here is on the size of the intake/exhaust ports. If the air outlet can be opened as wide as possible, it can promote more air flow and achieve effective ventilation. This is because pressure loss can have a direct impact.
Q: What is pressure loss?
A: The so-called pressure loss, in short, refers to the degree to which air is difficult to flow. The smaller the air channel ("flow path"), the greater the pressure loss.
Q: I see, so it's better to open the intake and exhaust ports as wide as possible!
A: That's exactly what it means. It seems that you have already started to understand! However, even if the intake and exhaust ports are wide open, it is difficult to achieve the desired effect if the control panel setting method is not ideal. For example, the distance between the wall and the control panel is related to this. Understood?
Q: Ah! Due to being blocked by walls, the airflow will decrease. That is to say, the wall is the pressure loss, causing a decrease in air volume, right? So, how much distance should be left?
A: It is best to be above 100mm. If not possible, customers should also be reminded to leave at least the same distance as the thickness of the fan. You may refer to this information.
Q: Really, the information is also very easy to understand.
A: There are also more effective setting methods that can be suggested to customers!
Q: Ensure the size of the intake and exhaust ports, as well as the distance between the wall and the control panel
It turns out that pulse signals also have voltage specifications!
Q: A A has inquired about pulse signals and asked me if 24V pulse signals can be used in conjunction with stepper motor drivers. I used to think that pulse signals were just the on-off switching of 5V voltage...
A: Have you encountered another difficult problem? Okay, before explaining the issue of pulse voltage, let me first explain the basic specifications of pulse signals to you using the Chinese version of the Comprehensive Catalog 2004/2005 version!
CW (pulse), CCW (direction of operation) pulse signal input pulse waveform
Please refer to page C-93 of the 2004/2005 edition of the Chinese comprehensive catalog for the pulse waveform of the driver pulse input section. )
The above figure shows the amplitude, voltage unit, and width of the rising and falling edges of the pulse signal. Any pulse signal that meets the above conditions can be used in conjunction with the driver of a stepper motor.
Q: So that's how it is. I also often browse the directory, it's strange why I didn't notice ... Huh? But the voltage is not indicated in this picture ..
A: Yes, so please take a look at this picture next!
■ Input circuit and wiring example
Pulse generator output
open collector
Internal circuit of the driver
200Ω
10-20mA
Please refer to page C-93 of the 2004/2005 edition of the Chinese comprehensive catalog for input circuits and wiring examples. )
Q: I know this picture! This is the wiring diagram that connects the input circuit using an optocoupler to the open collector output! The contactless AC speed controller also uses the same diagram.
A: Yes, this schematic diagram is an example of the wiring between the driver and pulse generator of the 5-phase stepper motor RK series ※. The CW pulse/CCW pulse signal input part is an optocoupler input method.
Q: What are the characteristics of optocoupler input?
A: An optocoupler is an electronic component that uses input current to convert electrical signals into optical signals for communication. Because it is not easily affected by noise, it can convey signals more accurately. However, it must be noted that there are certain limitations on the magnitude of the input current.
Q: I see.
A: The pulse input part of the RK series is shown in this figure and requires a current of 10mA to 20mA. If it is the 5V pulse signal you mentioned, it can be directly connected to the driver without connecting the resistor (R1) in the diagram.
Q: So, under what circumstances is this resistor (R1) used?
A: If a voltage exceeding 5V is connected to V0, the resistor (R1) shown in the diagram is required. For example, if the A's question is to connect a 24V voltage, a resistor should be connected to maintain the current value of the optocoupler within the range of 10mA to 20mA.
Q: So that's how it is! So, how should we calculate the resistance value?
A: For example, when inputting a current of 15mA, it can be calculated according to the following formula.
R1=V0-1.5 (V) (Note) 0.015 (A) -220 (Ω) R1=0.015 (A) V0-1.5 (V) (Note) -220 (Ω)
The voltage drop part of the optocoupler.
Q: Does this formula use Ohm's theorem?!
A: Yes, all of these need to be remembered in advance. The contents I just explained to you are all recorded in the specifications section of the drive. It's best for you to confirm as well. (Please refer to page C-82 of the Chinese version of the Comprehensive Catalogue 2004/2005.). )
Q: Are there many complex rules?!
A: I won't. If it is the EMP series or SG80301 pulse generator from Dongfang Motor, there is no need to worry about power specifications and it can be easily combined with the motor, so it can be used with peace of mind. Also, do you know that drivers can be divided into single pulse input and double pulse input?
Q: Is dual pulse input more efficient than single pulse input Ah。 What are the differences exactly?
A: Actually, it's not a high-performance issue. Dual pulse input is to input pulse signals into the CW input section and CCW input section respectively to make the motor run in the clockwise and counterclockwise directions. Single pulse input, on the other hand, involves inputting a pulse signal into one input unit and switching the direction of operation using another input unit. The single pulse input and double pulse input of the driver should be set according to the signal output of the pulse generator.
■ Dual pulse input mode
|Forward Pulse (CW) | ON OFF|
|Reverse Pulse (CCW) | ON OFF|
|Motor action | Clockwise direction | Counter clockwise direction|
Q: I see, now I finally understand. Thank you so much. Now I finally have the confidence to explain to the client. I'm going to contact the client right away. Ah。 (Falling)
A: Let me tell you, don't panic, calm down!
Introducing to you the driving method for making stepper motors more stable
Q: It's finally time for the exhibition! There are many As coming to visit.
A: This is an opportunity to fully utilize our knowledge. As the personnel responsible for explaining stepper motors, we must work hard today to ensure that our As return with a full load.
Q: Yes!
Q: Welcome (to As)! What kind of stepper motor are you looking for?
A: We often use stepper motors because they have a positioning function, which is very convenient. We also want to use this type of motor on the designed equipment, but with minimal vibration. Do you have any suggestions for motors?
Q: (For As) Is that so. If that's the case, what do you think of the 5-phase stepper motor combination RK series? Due to its smooth driving function, the vibration is relatively low. And using one switch can suppress vibration.
A: That's really great! But to what extent can it be improved?
Q: (For As) We have demo machines available, please try them out to experience the different vibrations at low speeds. Right side B is the operation at a full step angle of 0.72 degrees. Left side A is operating under smooth driving. What do you think?
A: It's completely different! The effect seems to be good. Also, I have heard of micro step level drivers. Is there any difference between this and others?
Q: (For As) The so-called micro step drive refers to the function of dividing and reducing the basic step angle of the stepper motor by 0.72 ° without mechanical elements such as reduction mechanisms. For example, under a 1/10 setting, each pulse is 0.072 'STEP. When each pulse is input, the step angle is subdivided, so the motor can operate smoothly, which can greatly reduce the vibration of the motor. However, when setting the step angle to 1/10, if you want to operate at the same amount as the basic STEP drive, you must set 10 times the pulse amount and frequency.
A: Setting the step angle to 1/10 requires 10 times the pulse amount. So that's what it means.
Q: (For As) The so-called smooth driving function refers to the ability to automatically perform micro step level driving without changing the pulse input setting.
A: I see. Smooth driving enables easy implementation of low vibration function without changing the settings of the upper controller.
Q: (For As) That's exactly the case.
A: I understand now, thank you. But there is still one place that I am not very familiar with.
Q: What is (for As)?
A: Microstep level functionality can achieve smaller STEP, I understand that. But isn't the motor of the deceleration model also capable of subdividing step angles? What is the difference in usage?
Q: (For As) Firstly, the micro step driver can reduce the step angle. However, there are still loads such as friction, as the subdivision of step angles in electrical aspects does not necessarily guarantee the accuracy of segmentation. In addition, the torque of the motor will not change. Microstep level driving is mainly a function of suppressing vibration.
A: Oh? What about the motor of the deceleration model?
Q: (For As) The motor of the deceleration model is finely divided into step angles in mechanical aspects, which can improve positioning accuracy. It can also achieve low vibration. The main reason is not only to reduce the vibration to one of the deceleration ratios, but also to ensure that the output shaft of the motor unit and the deceleration type motor operate at the same speed. As the speed of the deceleration type motor increases relatively, the vibration frequency of the motor can be avoided. However, due to the use of a deceleration mechanism, the available rotational speed has also been relatively reduced.
A: I see.
Q: (For As) Additionally, the advantages of the deceleration type motor are the ability to significantly increase torque and drive with greater inertia.
A: So the motor of the deceleration model reduces the pitch angle through mechanical structure, so its advantage is that it can significantly increase torque and drive with high inertia!
Q: (For As) That's exactly the case. However, depending on the type of gearbox, please note that backlash may occur during forward and backward positioning. Simply put, it is necessary to select micro step level drivers or deceleration type motors according to the requirements and specifications of the equipment. If selected properly, it can further enhance the overall specifications of the equipment.
A: So that's how it is. After returning, I will try to choose the most suitable motor for the equipment as soon as possible!
Q: (To the A) Thank you very much. Please make sure to consider our company's products. Welcome to make more use of 'Selected Services'. Yes, our company also provides As with 'selection services'. If you have already made a preliminary decision on the operating conditions of the equipment, you can easily inform us of the specifications of the mechanism by fax. Our company will conduct selection calculations for you and recommend the most suitable motor. Welcome to make more use of it.
A: Really? Will your company help us with the calculations? That's really good. We need to quickly intensify the discussion after returning. Thank you!
Q: (For As) Yes. We look forward to hearing from you. Thank you very much today.
Q: (Internally) When I just talked to the A about the differentiation of smooth drive function, micro step drive, and deceleration motor usage, the A was very happy. Moreover, it seems that we are about to entrust our company with the selection.
A: Is that so? That's really good. Did you tell the client that in addition to fax, they can also use online delegation?
Q: No, there isn't
A: If you remember to introduce it, you can also choose from online commissions. Fax delegation is one method, but there are six delegation formats available online, including ball screws, belts, pulleys, etc. As only need to input the conditions in numerical form and send them back to us, and they can easily complete the delegation selection! (The selected service can be entrusted through fax or the internet.)
Q: Yes... thank you. I'll go tell the client quickly.
What is the difference between electronic brakes and mechanical brakes?
Q: What is the difference between a brake used in conjunction with an AC motor and an AC motor with an attached electromagnetic brake? Aren't they all brakes?
A: I said to you, you've been in the company for two years now, how come you don't even know about this? There are also different types of brakes, which can be selected according to their intended use.
Q: A newcomer came to ask me this Q, and for some reason, I was a bit confused. Do you remember that you need a brake when you come to a sudden stop?
A: Yes. Brake is an electronic brake with instant stop function, which releases brake current to the motor to stop it in a short period of time.
Q: So is electromagnetic braking used for up and down driving?
A: Yes, this is because maintaining force is required when driving up and down. And electromagnetic brakes, because they can mechanically lock the motor, can ensure that the position of the load remains unchanged when stopping. Therefore, in addition to driving up and down, it is best to use a motor with an electromagnetic brake for any purpose that requires maintaining the load.
Q: So, can motors with electromagnetic brakes also stop instantly?
A: Of course, but the attached electromagnetic brake motor may experience a 2-3 turn over phenomenon. In contrast, the brake system only has an over turn of 1-2 revolutions.
Q: What does' over rotation 'mean?
A: The number of times the motor rotates from cutting off the power to stopping during rotation is called "over rotation". Taking the over rotation on the motor shaft under no-load conditions as an example, induction motors have 30-40 revolutions, while reversible motors also have 5-6 revolutions. If a reducer is used, the over rotation on the output shaft of the reducer is only 1/reduction ratio.
Q: I see. If only these two convenient brakes could be used together.
A: What are you talking about? Isn't it already there?
Q: Ah?
A: It's the "SB50" brake! As long as this electronic brake is used together with a motor with an electromagnetic brake, can't both load holding and instant stopping be solved? Why did you forget again?
What is the function of a capacitor?
Q: Huh? Can't move... why? I clearly connected the wires
A: What's wrong?
Q: I have already connected the wires, but the motor still won't move.
A: Let me see... it turns out so, no wonder it doesn't move. Because you didn't connect it to the capacitor. Have you carefully reviewed the wiring diagram?
Q: No... It was supposed to be connected to a capacitor. But what is a capacitor?
A: It's something connected to the motor! All single-phase power motors must be connected to capacitors.
Q: What are the functions of so-called capacitors?
A: Capacitors have two main functions.
(1) Control the direction of motor operation (convert single-phase power supply to two-phase)
(2) Drive the motor to generate torque (starting torque, rated torque)
And the capacitors matched with different motors are also different, so they must not be randomly matched.
Q: What would happen if inappropriate capacitors were used?
A: If a capacitor with excessive capacity is used, although it can also generate torque, the motor will generate abnormal heat and vibration. On the contrary, if capacitors with insufficient capacity are used, the torque will decrease, so it is not recommended to use capacitors with incompatible capacity.
Q: Hmm... but where is the capacity recorded?
A: It is recorded on the nameplate of the motor. Isn't it written here as 5 μ F! This represents the capacity of the capacitor.
Q: I see. So, what is the difference between the capacitors used in the motors stored in the warehouse that were circular and those used in the motors that were square?
A: Basically, as long as the capacity and voltage are the same, both can be used. But as the capacitor is made in different ways, its shape will also change accordingly. It is only possible that there may be differences in wiring methods, so attention should be paid when replacing capacitors.
Q: Do capacitors also need to be replaced?
A: The motor will eventually end its lifespan after long-term use. When purchasing a new single-phase motor, an electrical container will be included, and it would be better to replace it together with the motor at that time!
I learned a lot today, and I still need to learn more from you in the future!
Can Taiwanese voltage specification products be used in Japan?
Q: Can a 25W speed regulating motor with a voltage specification of 220V from Taiwan also be used in Japan?
A: Do you know what voltage is used in Japan?
Q: Huh? Isn't he the same as us?
A: Japan uses single-phase 200V 50/60Hz!
Q: Isn't that okay? The specifications of speed regulating motor products from Japan's Dongfang Motor can be used within the range of single-phase 200 ± 10%, right?
A: Although this is the voltage variation range allowed by the motor, it does not actually guarantee that it is the optimal usage range! If the voltage fluctuates instantaneously within the allowable range, the motor will not produce abnormal phenomena. However, if it is continuously used at a voltage of 200V, it will cause insufficient output of the motor (not reaching the rated output), resulting in a decrease in torque and even the inability to drive the load. On the contrary, if a 200V motor is used in a 220V environment, although the output torque of the motor can be increased, the temperature of the motor will be higher than in normal use, and not only that, it may also shorten the life of the motor! Can't we recommend the selected motor to the customer for use this time?
Q: Hmm, yes. What would be better to introduce?
A: By the way, don't we have MSS and W series products that have both passed the world standard certification and meet Japanese standards? There is also an introduction on the Chinese comprehensive catalog! MSS425-402WJ is the most suitable for this case. (Voltage specification 200V)
Q: Yes, the voltage specification is 200/220/230V and it can be used. But wouldn't it be a problem to suggest customers use substitutes? For example, there may be differences in external dimensions and so on
A: Don't worry! Because the motor size is consistent, customers can directly connect it with the selected reducer for use. Moreover, in addition to the protective cover of the attached electrical container, there are also relay cables for customers to use with peace of mind.
