[0002] The starter motor is a motor installed on the generator set, driven by a battery, and used to start the generator. The principle of the generator starter motor is very simple, which is to use the torque generated by the rotation of the motor to drive the generator to rotate. Specifically, when the motor power is turned on, the motor rotor begins to rotate, generating a rotating magnetic field. Since the generator rotor is connected to the motor rotor, the torque generated by the rotation of the motor will be transmitted to the generator rotor through the bearing, driving the generator to rotate. When the generator starts to generate electrical energy, the motor gradually slows down until it stops rotating.

[0003] The starter motor can reduce the trouble of manual starting of the generator set, start quickly, and can be widely reused. Therefore, the generator starter motor is widely used in various power generation equipment, such as automobile generators, ship generators, wind turbines, gas generators, etc. In these equipment, the generator starter motor plays a very important role, which can help the generator start quickly and run.
