Maintenance of DC Brushless Motors
(1) Before disassembly, use compressed air to blow off the dust on the motor surface and wipe it clean.
(2) Select the working place for motor disassembly and clean the on-site environment.
(3) Be familiar with the structural characteristics and maintenance technical requirements of electric motors.
(4) Prepare the tools (including special tools) and equipment required for disassembly.
(5) In order to further understand the defects in the operation of the motor, if conditions permit, inspection and testing can be performed before disassembly. To do this, the motor will be load tested and each component of the motor will be examined in detail for temperature, sound, vibration and other conditions. Voltage, current, speed, etc. will be tested and then the load will be disconnected. Carry out no-load inspection test separately, measure no-load current and no-load loss, and keep records.
(6) Cut off the power supply, remove the external wiring of the motor, and make records.
(7) Choose 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, usually converted to 75°C.
(8) Test the absorption rate K. When the absorption rate is greater than 1.33, it indicates that the motor insulation is not affected by moisture or the degree of moisture is not serious. For comparison with previous data, the absorption ratio measured at any temperature also needs to be converted to the same temperature.
Brushless Hair Dryer Principle
Brushless hair dryer. The principle is mainly based on electromagnetic induction technology Q and electronic control technology Q. The brushless motor is the core component of this hair dryer. It consists of a stator, a rotor, a sensor, etc. It can efficiently convert electrical energy into mechanical energy to generate strong wind. The working principle of the brushless motor is to use the rotor to generate reverse torque under the action of a magnetic field to form an external airflow. In a brushless motor, the commutation work is completed by the control circuit in the controller (usually a Hall sensor Q+ controller, and the more advanced technology is a magnetic encoder Q). Brushless motors adopt electronic commutation, the wire does not move and the magnetic pole rotates. Brushless motors use a set of electronic equipment to sense the position of the permanent magnet poles through Hall elements. Based on this perception, electronic circuits are used to timely switch the direction of the current in the coil to ensure that the magnetic force in the correct direction is generated to drive the motor.
In addition, 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.
