FAQ

Q: What is your payment term?

A: We accept 50% down payment T/T in advance and 50% balance payment T/T before shipment.

 

Q: What sets apart a unipolar stepper motor from a bipolar one?

A: Unipolar stepper motors have center-tapped windings with simpler control, allowing current through only half the winding. Bipolar stepper motors have separate windings, enabling full-winding current flow, higher torque, and precision control but requiring more complex drivers.

 

Q: Are your motors' prices competitive？

A: Yes. All of our motors are made in house, so that we can decrease the cost while ensuring good quality.
