in order to further understand the defects of brushless dc motor running, when conditions permit, can be checked before disassembly test. Therefore, brushless dc motor load, commissioning detailed check the temperature of the parts of the brushless dc motor, sound, vibration, etc. , and test the voltage, current, speed, etc. , and then disconnect the load, no-load check experiment was carried out respectively, and measurement of no-load loss and no-load current and and make records. Brushless dc motor as before to do so before 1, remove, check the appearance of the brushless dc motor integrity, to use compressed air to blow away the dust on the surface of the brushless dc motor, and wipe the surface dirt. 2, choose decomposition of brushless dc motor of the workplace, clean up the scene environment. 3, familiar with brushless dc motor structure and maintenance of the technical requirements. 4, to remove the special tools and equipment required. 5, to cut off the power supply, demolition of brushless dc motor wiring and make records. 6, choose a multimeter to test the insulation resistance of the brushless dc motor. In order to compare the last overhaul during measuring insulation resistance value, to determine the insulation of the brushless dc motor trend and insulating state, different temperature measuring insulation resistance value shall be converted to the same temperature, the average is 75 ℃. 7, test, absorption rate k. When the absorption rate is greater than 1. 33, the brushless dc motor insulation described not affected by the wet or damp it's nothing serious. In order to comparing with previous data, also will any temperature measured absorption rate should also be converted to the same temperature. 8, all problems after everything checked out, deal with the problems found, reassemble the complete, and run the tests.
