How to Maintain Your Brushless DC motor?

The brushless DC motor not only has the advantages of reliable operation and convenient maintenance of the AC motor, but also has the advantages of high operating efficiency and good speed regulation performance of the DC motor. Because it is not restricted by mechanical commutation and easy to achieve large capacity and high speed. It has broad application prospects in aerospace, military, numerical control, metallurgy, medical equipment and other fields. In order to make the function of the brushless DC motor better, we must pay attention to daily maintenance and maintenance, but how can we maintain it to extend its service life and improve our work efficiency?

Before disassembly, clean the motor surface with compressed air and wipe off the dirt.
Select the working place where the motor disintegrates and clean up the on-site environment.
Familiar with motor structure characteristics and maintenance technical requirements.
Prepare necessary tools (including special tools) and equipment for disassembly.
In order to further understand the defects in motor operation, check test can be done before disassembly when conditions permit. For this purpose, the motor load test run, detailed inspection of the motor parts temperature, sound, vibration and other conditions, and test voltage, current, speed and so on. Then disconnect the load and do a no-load inspection test separately to measure the no-load current and no-load loss and make records.
Cut off the power supply, remove the external wiring of the Brushless DC motor, and make records.
Select appropriate voltage megohm meter to test the insulation resistance of the brushless DC motor. Maintenance in order to keep pace with The Times when measured insulation resistance compared to determine the motor insulation change trend and insulating state, should be measured under different temperature insulation resistance value of the conversion to the same temperature, the average conversion to 75 ℃.
Test the absorption ratio K. When the absorption ratio is greater than 1.33, it indicates that the BLDC motor insulation has not been damped or the degree of dampness is not serious. For comparison with previous data, the absorption ratio measured at any temperature is also converted to the same temperature.
