FAQ

Q: What is the relationship between stepper motor speed and torque?

A: There is an inverse relationship between stepper motor speed and torque, meaning that as speed increases, torque decreases.

 

Q: What are the control modes for stepper motors?

A: Control modes for stepper motors include open-loop control and closed-loop control. Open-loop control involves controlling the motor without position feedback, while closed-loop control involves using position feedback to control the motor.

 

Q: Can you offer a sample for testing?

A: Yes, we can send you a sample to test the quality.

 

Q: How does a stepper motor work?

A: A stepper motor is controlled by a sequence of electrical pulses that cause it to rotate in fixed angular or step increments. Each pulse moves the motor at a set distance or angle, allowing for precise control of the motor's position and speed.
