Frequently Asked Questions
How to select a suitable motor?

If you have motor pictures or drawings to show us, or you have detailed specs like voltage, speed, torque, motor size, working mode of the motor, needed lifetime and noise level etc, please do not hesitate to let us know, then we can recommend a suitable motor per your request accordingly.

Do you have customized service for your standard motors?

Yes, we can customize per your request for the voltage, speed, torque and shaft size/shape. If you need additional wires/cables soldered on the terminal or need to add connectors, or capacitors or EMC, we can make it too.

Can I have samples for testing first?

Yes, definitely you can. After confirming the needed motor specs, we will quote and provide a proforma invoice for samples. Once we get the payment, we will proceed with the samples accordingly.

How do you make sure motor quality?

We have our own inspection procedures: for incoming materials, we check signed samples and drawings to ensure qualified materials; for the production process, we have tour inspections and a final inspection to guarantee qualified products before shipping.

What's your lead time?

Generally speaking, our regular standard product will need 25-30 days, and a bit longer for customized products. We are flexible on lead times depending on the specific orders.

What certifications do you have?

We currently hold CE, ROHS, ISO13485, IATF16949, and REACH certifications.
