FAQ

Q: What is the delivery time of your motors?

A: In general, the production lead time of our motors is about 30-35 days (For urgent orders, we can expedite). Transportation time is depending on the transportation method that our customers choose.

 

Q: Where is your factory located?

A: Our factory is located in Changzhou City, Jiangsu Province, China.

 

Q: What's the function of a stepper motor drive?

A: It acts as an interface between the control system (such as a microcontroller or PLC) and the stepper motor. The primary function of the driver is to regulate the current flowing through the motor windings and control the timing and sequence of the electrical pulses that move the motor. The driver ensures that the motor receives the required power and accurately follows the desired motion profile.
