What is the cause of Magotan motor failure?

Causes of Magotan motor failure: the internal coil of the motor is damaged, the internal carbon brush of the motor is damaged, and the voltage regulator is damaged. 1. Magotan's motor has a motor and a generator, both of which have coils and carbon brushes inside. The carbon brush will continue to wear with the driving of the vehicle, and eventually the carbon brush will wear to the limit, with poor contact, and eventually it will not generate electricity or the motor will not run. 2. The most common motor faults: the carbon brush of the starter is worn to the limit and cannot be started, and the carbon brush of the generator is worn to the limit and cannot generate electricity. Both failures will cause the vehicle to fail to start. Although the generator does not generate electricity, the engine will not turn off immediately, but with the gradual consumption of battery power, it will automatically turn off because of the low voltage.
