FAQ

Q: Where are your motors sold?

A: Our motors are sold globally and exported to various countries, including the United States, South Korea, Sweden, Germany, Italy, and many others. We have gained the trust and satisfaction of both domestic and international customers.

 

Q: Can stepper motors experience step loss?

A: Yes, stepper motors can experience step loss under certain conditions. Factors such as exceeding the motor's load torque capacity, inadequate power or drive, and mechanical issues like binding or excessive friction can lead to step loss.

 

Q: Are stepper motors reversible?

A: Yes, stepper motors are inherently reversible. By reversing the sequence of the input pulses sent to the motor, it can rotate in the opposite direction, allowing for bidirectional control.

 

Q: Can a stepper motor operate without a driver?

A: No, stepper motors generally require a dedicated driver or controller to operate correctly. The driver or controller is responsible for delivering the appropriate current and timing of electrical pulses to the motor coils, ensuring accurate and controlled motion.
