[0049] First, place the rotor to be cleaned on the workbench inside the box 1, and its fixing method is consistent with the existing permanent magnet rotor fixing method, that is, the butterfly nut 12 and the bracket 13 are used to fix the permanent magnet rotor to the workbench inside the box 1, and then, turn on the left displacement switch 21 and the right displacement switch 22, the left displacement switch 21 and the right displacement switch 22 control the left electromagnetic relay 41 and the right electromagnetic relay 42 to start at a time, and the timed start of the left electromagnetic relay 41 and the right electromagnetic relay 42 respectively drives the corresponding left hydraulic valve 51 and the right hydraulic valve 52 to start, and the start of the left hydraulic valve 51 and the right hydraulic valve 52 drives clean water through the inside of the filtered water tank 7, which is pressurized by the high-pressure cleaning pump 11 and finally flows into the inside of the high-pressure cleaning machine 10 to rinse the permanent magnet rotor inside the high-pressure cleaning machine 10.
