(1) Before disassembling the BLDC motor, use compressed air to blow off the dust on the surface of the motor, and wipe the surface dirt clean.
(2) Select the work site where the motor disintegrates and clean up the site environment.
(3) It is recommended that the BLDC motor factory be familiar with the structural characteristics of the motor and the technical requirements for maintenance.
(4) Prepare the necessary tools (including special tools) and equipment for dismantling.
(5) In order to further understand the defects in the operation of the BLDC motor, an inspection test can be done before disassembly if conditions permit. For this reason, BLDC motor manufacturers recommend that the motor be tested with the load on, check the temperature, sound, vibration, etc. of each part of the motor in detail, and test the voltage, current, speed, etc., and then disconnect the load and do a no-load operation alone. Check the test, measure the no-load current and no-load loss, and make a record.
(6) Cut off the power supply, remove the external wiring of the motor, and make a record.
(7) Use a megohmmeter with a suitable voltage to test the insulation resistance of the BLDC motor. In order to compare the insulation resistance value measured in the last inspection to judge the change trend and insulation state of the motor insulation, the insulation resistance values measured at different temperatures should be converted to the same temperature, generally converted to 75°C.
(8) Test absorption ratio K of BLDC motor. When the absorption ratio is greater than 1.33, it indicates that the motor insulation has never been damp or the damp degree is not serious. In order to compare with previous data, it is also necessary to convert the absorption ratio measured at any temperature to the same temperature.
