What is the reason for the step loss of the stepper motor?

The stepper motor loses its step, mainly due to two reasons: 1. The motor loses its step. Stepping out due to torque decrease after the rotational speed exceeds a certain frequency; The driving circuit is unstable and lacks sufficient pulse width, resulting in stepping out; Loss of step caused by rotor resonance at specific frequencies;
2. Transmission impact. Insufficient elasticity of the synchronous belt can cause an increase in the required torque during startup, resulting in the motor being unable to rotate and losing step; The synchronous belt has too much elasticity, and the motor is pulled back by the synchronous belt after turning over.

1. If the transmission accuracy of the synchronous belt or gear is not enough, it will cause the stepper motor to lose step.
2. If there are problems with the stepper motor driver, such as insufficient driving voltage or low driving current setting, it can also cause the stepper motor to lose step.
3. For example, problems such as resonance and resonance in mechanical systems can cause the stepper motor to lose its step.
4. Power fluctuations or interference may also cause the stepper motor to lose its step.
