FAQ

Q: How does a stepper motor operate?

A: A stepper motor functions by receiving a sequence of electrical pulses that induce rotation in fixed angular or step increments. Each pulse moves the motor by a predetermined distance or angle, enabling precise control over the motor's position and speed.

 

Q: What is the minimum order quantity for your products?

A: The minimum order quantity (MOQ) requirement varies from model to model. We are open to discussing and determining the MOQ on a case-by-case basis to meet your specific needs.

 

Q: What about the quality of your products?

A: Our company is ISO9001 and ISO14001 certified, and all of our motors are CE certified.

 

Q: Can we visit your factory before placing the order?

A: Yes, it’s our pleasure. And it would be helpful for us to set up a good relationship for business.
