What items should be tested in the motor driver exam?

Motor drive test generally needs to test the following items:

Output characteristic test: by testing the output characteristics of the driver, including output voltage, output current, output power and other parameters, it is determined whether its output capability and efficiency meet the requirements.

Speed regulation performance test: by testing the speed regulation performance of the driver, the speed regulation accuracy of the driver under different loads and the stability of acceleration, deceleration and reverse switching can be tested.

Adjustment parameter test: test the control parameters of the driver, including the maximum output current, acceleration time, deceleration time, etc. , to determine whether the performance of the driver control system meets the requirements.

Over-current protection test: test the over-current protection function of the driver, and test whether the driver can stop output in time and effectively by simulating abnormal situations such as overload or short circuit, so as to protect the motor and the driver itself.

Fault diagnosis test: test the fault diagnosis function of the driver, and test whether the driver can accurately diagnose the fault type and fault location by simulating different types of faults, thus providing effective fault alarm and protection.

In a word, it is necessary to comprehensively test the performance and reliability of the motor driver to ensure its stability and safety in practical application.
