The brushless DC motor is composed of a motor body and a driver, and is a typical mechatronic product. Brushless motors refer to motors without brushes and commutators (or collector rings, also known as commutator-less motors. The following editor will introduce you to the precautions for maintenance of brushless DC motors.
1. Before disassembling, use compressed air to blow off the dust on the surface of the DC brushless motor, and wipe off the dirt on the surface.
2. Select the working place where the motor is disassembled and clean up the site environment.
3. Familiar with the structural characteristics of the motor and technical requirements for maintenance.
4. Prepare the tools needed for disassembly (including special tools and equipment.
5. In order to further understand the defects in the operation of the DC brushless motor, if possible, an inspection test can be done before disassembly. For this reason, put the motor on the load for a trial run, 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, do a separate no-load inspection test, and find out that it is empty. Make a record of the load current and no-load loss.
6. Cut off the power supply, remove the external wiring of the motor, and make a record.
In a word, during the operation of the brushless DC motor, monitor the changes of its current and temperature, and solve the problem in time.
