FAQ
What is the insulation level of the motor?
Dear, the insulation level is Class B (temperature resistance of 130 ℃), suitable for most workshop environments (temperature ≤ 40 ℃). If you need higher temperature resistance (such as 155 ℃), you can choose Class F, which costs an additional 30 yuan per unit
Can the motor be used in low temperature environments (-15 ℃)?
The regular version is not suitable (the lubricating grease will solidify), and a low-temperature special version (with -40 ℃ special lubricating grease added) needs to be selected. It only costs 20 yuan per unit and is suitable for use in winter workshops in Northeast China
What safety precautions should be taken when wiring?
Dear, 3 points of safety: ① The power must be cut off and the wiring must be connected (the test pen should be used to check if there is no power); ② The grounding wire should be connected (yellow and green wires should be connected to the grounding pole); ③ The terminals should not be exposed to copper (wrapped with insulating tape) to prevent electric shock
Can you control your motor with a frequency converter?
Sure, the three-phase motor is compatible with a frequency converter (such as Delta VFD007M43B), with a wider speed range (10-1500 rpm). The original speed controller needs to be removed, and customer service can provide a wiring plan
What is the rated speed of the motor?
Dear, the rated speed of the motor shaft is 1400 revolutions per minute (50Hz), and the output speed is 1400 ÷ reduction ratio. For example, the reduction ratio is 1:20, and the output speed is 70 revolutions per minute. It is suitable for slow speed equipment
How to determine if the motor is overloaded?
Dear, there are two methods: ① Measure the current (clamp meter measurement, exceeding 1.2 times the rated current is overload); ② Touching the outer shell (over 80 ℃ and continuously heating up), overloading will burn the coil, so avoid it
How to deal with the abnormal noise of "clicking" when the motor is running?
Dear, it's the sound of gear wear. Stop the machine immediately! Contact customer service and after-sales service. Continuing to use will damage the shaft, which is covered by the warranty and will be replaced for free. If the gear is replaced due to human factors (such as overload), it will cost 15 yuan
How to maintain a deceleration motor to extend its lifespan?
Dear, 3-step maintenance: ① Tighten the wiring terminals every 3 months; ② Add lithium based grease (at the bearing) once a year; ③ Avoid water ingress into the motor (cover with waterproof cloth on rainy days), which can extend its lifespan by 2 years
What should I do if the motor casing is severely heated (over 80 ℃)?
Dear, power off immediately! Reason: ① Excessive load (such as 60W with 10kg) → Switching to higher power; ② Poor ventilation (with debris around) → Clean the space, cool down, and then use again
What should I do if the motor with brakes doesn't respond to the brakes?
Dear, check if the brake coil is powered on (resistance measurement of 100-200 Ω is normal); ② Have the brake pads been worn out (it is normal to have a thickness of ≥ 3mm when disassembled)? Replace the brake pads and send the parts to customer service (25 yuan)
How to solve the problem of large vibration during motor operation?
Dear, check 2 points: ① Whether the motor screws are tightened (cannot be moved with a wrench); ② Is the motor shaft and equipment shaft aligned (deviation ≤ 0.1mm)? After adjustment, the vibration will decrease by 50%
What should I do if the speed of the speed regulating motor fluctuates?
Dear, reason: ① Poor contact of the governor knob (unplugged and reinserted); ② The power supply voltage is unstable (measured with a multimeter, it needs to be stable at 220V ± 10%), and replacing the speed controller only costs 30 yuan
What is the reason why the motor does not start after being powered on?
Dear, check three points: ① Check if the wiring is loose (tighten the terminals); ② Is the power supply voltage sufficient (220V needs to be ≥ 200V); ③ Is the load exceeding (such as 90W with 5kg load), but still unable to contact customer service
How to wire the deceleration motor?
Dear, single-phase 220V: live wire → governor L → motor red wire, neutral wire → governor N → motor blue wire; Three phase 380V: Three live wires → Motor U/V/W (in no particular order), customer service can send a wiring diagram
Can the motor still be repaired after 10 months of use?
Sure, dear. The warranty period is within 14 months. You can send it back according to the after-sales process, and we will replace it for free. After replacement, the motor still enjoys a 3-month warranty period (extended after-sales protection)
What is the warranty period for DPG motors?
Dear customer, the warranty period is 14 months (calculated from the date of receipt), and there is no free replacement for non-human damage (such as coil burning or gear cracking); Artificial damage (such as water ingress) incurs cost for repair (only parts price charged)
Can we send the customer's address on behalf of them?
Sure, please note "dropshipping"+customer address. The packaging does not include store information (neutral packaging) to protect your customer resources. There is no limit to the number of dropshipping (even one unit can be dropshipped)
Can I exchange for the wrong model?
Dear, unused and well packaged, can be exchanged within 7 days, and you will bear the round-trip shipping cost; If we send the wrong model, we will bear the shipping cost and exchange it unconditionally without you having to pay
Can enterprise procurement sign contracts?
Sure, after providing the company's business license, draft a purchase contract (including warranty terms) within 1 hour, support corporate payment (shipment upon receipt), and issue an invoice
Can we send samples for trial first?
Sure, dear. The samples will be sold at their original price (without discount). For subsequent bulk purchases of over 100 units, the sample fee will be refunded, and we will bear the sample shipping cost (via SF Express). If you are not satisfied with the 7-day trial, you can receive a refund
