Brushless DC motors use direct current, which is divided into high and low voltages. This generally refers to the integration of brushless DC motor bodies and drivers. Brushless DC motor common knowledge is as follows:

(1) Before disassembling, use the compressed air to blow dust on the surface of the motor and wipe the surface dirt clean.

(2) Select the workplace where the motor is disassembled and clean the site environment.

(3) Familiar with the structural characteristics of the motor and technical requirements for overhaul.

(4) Prepare tools (including special tools) and equipment required for disintegration.

(5) In order to further understand the defects in the operation of the motor, a check test can be performed before disassembly in conditions. For this purpose, the motor is loaded with a load and tested, and the temperature, sound, vibration, etc. of each part of the motor are examined in detail, and the voltage, current, and speed are tested. Then the load is disconnected and a no-load inspection test is performed separately. Load current and no-load loss, make a record.

(6) Cut off the power supply, remove the external wiring of the motor, and make a record.

(7) Select the appropriate voltage megohmmeter to test the motor insulation resistance. In order to judge the insulation trend and insulation status of the motor in order to compare with the insulation resistance measured during the last inspection, the insulation resistance value measured at different temperatures should be measured. Converted to the same temperature, generally converted to 75 °C.

(8) Test Absorption Ratio K. When the Absorption Ratio is greater than 1.33, it indicates that the motor insulation has not been affected by moisture or moisture. In order to compare with the previous data, the absorption ratio measured at any temperature is also converted to the same temperature.
