the master control module is connected with the mover module to be tested and used for controlling the current input of the mover module to be tested;
detecting magnetic field information generated after the power of the mover module to be detected is switched on by using a detection module, and sending the magnetic field information to the main control module;
and the main control module identifies the magnetic field information and adopts a display module to display the polarity detection result of the mover module to be detected.
