[0002] The motor controller itself contains many components and types, including metal and non-metal structural parts, power semiconductor devices, various electronic components, sensor devices, and software control units. Its testing is relatively complicated, and traditional testing methods are difficult to complete testing State parameters of the motor controller;

[0003] The traditional motor controller test technology usually uses motor load. The test environment requires a bench, dynamometer load motor, cooling water tank, etc., which takes up a lot of space. The motor controller cannot be tested online, and the test efficiency is low, the noise is large, and human factors are many questions

[0004] Moreover, most of the traditional motor controller test methods cannot realize the complete test of the state parameters of the high-voltage and low-voltage circuits, and do not have functions such as active and passive discharge.
