Several Practical Methods in Motor Repair
Various situations may be encountered during motor repair. If reasonable methods are adopted, detours can be avoided during repair, achieving twice the result with half the effort. Summarize the experience and experience in daily maintenance work into several practical methods for motor repair, mainly including methods for dealing with and repairing problems such as reduced insulation resistance of the motor, grounding point in the stator winding slot, inter turn short circuit of the winding, broken cage rotor bars, shooting of "parallel head covers" between motors, dismantling of old windings, wear and tear of rotor journals and end cover bearing chambers, for reference.

Characteristics and Types of Brushless DC Motors
Magnet rotation "is the most significant feature of brushless DC motors, which utilizes the magnetic field generated by the current in the stator coil to rotate the rotor with magnets. The switching of current is controlled by sensors and integrated circuits Outer rotor type (rotating part outside the stator) Advantages: It can achieve strong torque and stable speed during constant rotation Shortcomings: The rotor volume is relatively large (low sensitivity), and safety measures need to be taken into account as the rotating part is located outside the stator
