A broken current control chip will cause the stepper motor to fail to excite.
Current control chip is one of the key components of the stepper motor, it is responsible for controlling the current size and direction of the stepper motor.
When the current control chip is damaged, the flow of current cannot be controlled correctly, resulting in the stepper motor cannot be excited normally.
Without the excitation of the current, the stepper motor cannot move according to the predetermined stepping Angle, and thus cannot work normally.
In addition to the current control chip, damage to other components may also cause the stepper motor to fail to excite.
For example, damage to components such as capacitors and resistors in the drive circuit, or abnormal power supply may affect the excitation effect of the stepper motor.
Therefore, when investigating the problem that the stepper motor cannot be excited, it is necessary to comprehensively consider the normal operation of each component and investigate the possible causes of failure one by one.
