Stepper motors may encounter various problems during application, which are often related to multiple factors. The following are some problems and analysis that may occur during stepper motor application:

Stepper motor does not run after power on

This may be caused by improper driver parameter settings, poor connection between motor and driver, motor failure, etc. 1) Check whether the connection between the motor and driver is good and whether the start command is received correctly; 2) Check whether the control system has sent a pulse signal to the stepper motor driver and whether the driver parameter settings are correct; 3) Check the motor itself for failures: whether it is overloaded and blocked (the motor usually makes a whistling sound at this time); whether there is an abnormality (you can check whether it is stuck or jammed by rotating the motor shaft).

Stepper motor out of step

Stepper motor out of step means that the actual position of the motor is inconsistent with the command position during operation. This may be caused by excessive motor load, insufficient driver current, improper driver subdivision number setting, etc. The solution to this problem is to reduce the motor load, increase the driver current, adjust the driver subdivision number, etc.

The stepper motor noise is too loud

This may be caused by poor connection between the motor and the driver, loose internal structure of the motor, etc. In order to reduce noise, it is necessary to check whether the motor bearings are worn or loose, whether the transmission parts are lubricated, and whether the connection between the motor and the driver is good.

Stepper motor heats up too high

Stepper motor heats up too high may be caused by excessive motor load, excessive driver current, poor motor heat dissipation, etc. In order to avoid motor overheating, it is necessary to reduce the motor load, adjust the driver current, strengthen motor heat dissipation, etc.

The emergence of these problems often affects the normal operation of the stepper motor and even causes it to be damaged. Therefore, in order to ensure that the motor can work stably and efficiently, regular maintenance and inspection are required to find out the cause of the fault and solve it in time.
