How do you get a broken stage
Is very simple, will be another shaft with the specifications of the motor (generally more than one the same device driver and motor) on the drive you doubt, if can work normally drive is good, if not working that's not a matter of drive motor problem. The method is simple, practical and reliable. If the machine does not have a similar motor or actuator that can be interchanged, it will be exchanged for the same driver or motor on the other device.
There are four lines that are interlinked, the resistance is the same, there is no leakage of the shell, and the rotation is flexible. good
If you choose to intelligent stepper drive such as the British EZM series drives, this kind of problem is very easy to recognize: if the motor internal short circuit, the drive will be submitted to the over-current fault; If the motor winding opens, the driver fails to report. If the internal parts of the motor have problems, they will be noisy and abnormal.
Determine if the green indicator light is bright, if not, the power supply is defective. When you don't answer the motor
