Maintenance of DC Brushless Motors
(1) Before disassembly, use compressed air to blow off the dust on
the surface of the motor and wipe it clean.
(2) Select the working location for motor disassembly and clean the
on-site environment.
(3) Familiar with the structural characteristics and maintenance
technical requirements of the motor.
(4) Prepare the necessary tools (including special tools) and
equipment for disassembly.
(5) In order to further understand the defects in the operation of
the motor, an inspection test can be conducted before disassembly
if conditions permit. To this end, the motor will be tested with a
load, and the temperature, sound, vibration, and other conditions
of each part of the motor will be checked in detail. The voltage,
current, speed, etc. will be tested, and then the load will be
disconnected. A separate no-load inspection test will be conducted
to measure the no-load current and no-load loss, and records will
be kept.
(6) Cut off the power supply, remove the external wiring of the
motor, and keep records.
(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 trend of insulation change and insulation status of the motor,
the insulation resistance values measured at different temperatures
should be converted to the same temperature, usually converted 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.
Brushless hair dryers usually contain an electric heating element Q, which is used to heat the air to form hot air. The control circuit is responsible for controlling the speed and direction of the motor to realize different functions of the hair dryer, such as speed regulation and temperature control.
