FAQ

Q: What is the step angle of a stepper motor?

A: The step angle of a stepper motor refers to the angular displacement produced by the motor per electrical input pulse. It represents the smallest increment of rotation that the motor can achieve. The step angle is typically specified in degrees or radians.

 

Q: What is the difference between a stepper motor driver and a controller?

A: A stepper motor driver provides the necessary current and control signals to drive the motor, while a controller typically includes additional functionalities such as motion profiles, speed control, and communication interfaces.

 

Q: Do your motors meet international environmental requirements?

A:  In order to meet international environmental requirements, our products have also obtained ROHS and REACH  environmental certificates.

 

Q: What is your minimum order quantity, and can you send me samples?

A: MOQ requirement is different from model to model, and this can be discussed case by case. And we can send you samples.
