Brushless motors have a longer lifespan than brushed motors, but if used properly in daily life, it is more beneficial for extending their use. So, as a brushless motor manufacturer - Topband manufacturer answers the eight common sense of using brushless motors, the content is as follows:
1、 Before disassembling the
brushless motor, the surface dust of the motor should be blown clean with compressed air and the surface dirt should be wiped clean.
2、 Choose a work location for disassembling the brushless motor and clean up the on-site environment.
3、 Familiar with the structural characteristics and maintenance technical requirements of brushless motors.
4、 Prepare the necessary tools (including specialized tools) and equipment for disassembly.
5、 In order to further understand the defects in the operation of brushless motors, an inspection test can be conducted before disassembly if conditions permit. To this end, the brushless motor is put on a load test run, and the temperature, sound, vibration, and other conditions of each part of the motor are checked in detail. The voltage, current, speed, etc. are also tested. Then, the load is disconnected and a separate no-load inspection test is conducted to measure the no-load current and no-load loss, and records are kept.
6、 Cut off the power, remove the external wiring of the brushless motor, and keep a record.
7、 Select a suitable voltage megohmmeter to test the insulation resistance of the motor. In order to compare the insulation resistance values measured during the last maintenance to determine the insulation change trend and insulation status of the motor, the insulation resistance values measured at different temperatures should be converted to the same temperature, generally to 75 ℃.
8、 Test the 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 the degree of moisture is not severe. In order to compare with previous data, it is also necessary to convert the absorption ratio measured at any temperature to the same temperature.
