FAQ(Q=Question, A=Answer)
Q: How to select a suitable motor?
A: If you have pictures or drawings to show us, or you have detailed specs like the voltage, speed, torque, motor size, the working mode of the motor, needed lifetime and noise level, etc, please do not hesitate to let us know, then we can recommend suitable motor as you requested accordingly.
Q: Do you have a customized service for your standard motors?
A: Yes, we can customize as you requested for the voltage, speed, torque, and shaft size/shape.
Q: Can I have samples for testing first?
A: Yes, definitely you can. After confirming the needed motor specs, we will quote and provide a proforma invoice for samples.
Q: How do you make sure motor quality?
A: We have our own inspection procedures: for incoming materials, we have signed samples and drawing to ensure qualified incoming materials; for the production process, we have a tour inspection in the process and a final inspection to ensure qualified products before shipping.
