[0002] As we all know, the starting of the engine requires the support of external force, and the car starter plays this role. Generally speaking, the starter uses three components to realize the entire starting process. The DC motor introduces current from the battery and causes the starter drive gear to produce mechanical movement; the transmission mechanism meshes the drive gear into the flywheel ring gear and can automatically disengage after the engine starts; the on and off of the starter circuit is controlled by an electromagnetic switch. Among them, the motor is the main component inside the starter, and its working principle is the energy conversion process based on Ampere's law, that is, the force of the energized conductor in the magnetic field. Before the engine runs with its own power, it must rotate with the help of external force. The process of the engine transitioning from a static state to being able to run independently with the help of external force is called the start of the engine. The electric starting method is easy to operate, starts quickly, has the ability to start repeatedly, and can be controlled remotely, so it is widely used in modern cars. The electromagnetic power of the armature assembly used in the current car starter motor is low, the magnetic flux of the motor is not uniform, and the motor operation is not stable and efficient under harsh working conditions.
