Background

A stepper motor is a motor that converts an electrical pulse signal into a corresponding angular or linear displacement. Each time a pulse signal is input, the rotor rotates by an angle or further, the output angular displacement or linear displacement is proportional to the input pulse number, and the rotating speed is proportional to the pulse frequency. Therefore, the stepper motor is also called a pulse motor, and after the stepper motor is assembled, the moment of the stepper motor needs to be tested in order to ensure the working performance of the stepper motor.

When a stepping motor is tested, a common moment testing device generally locks the stepping motor after the stepping motor is electrified, then a rotor of the motor is connected with a moment instrument through a sleeve joint clamp, finally the motor rotates, and the moment when the moment instrument rotates is read, so that moment data can be monitored.
