How a car starter works
1.When the ignition switch is closed, the two coil windings (holding coil S-ground and suction coil S-M) are energized. It is worth noting that due to the low resistance of the suction coil, a large current flows through it. This coil is connected in series with the motor circuit, and under the action of current, the motor will slowly rotate to facilitate the engagement of the small gear and flywheel;
2.At the same time, the magnetic field generated in the coil attracts the iron core to push the small gear in and mesh with the flywheel ring gear. At this time, the high load main contact B is short circuited by a short-circuit piece, that is, the short-circuit switch is closed, the main circuit of the starter is connected, and the armature winding is provided with a large starting current by the battery and generates a strong starting torque; Meanwhile, the pull-in coil (S-M) is short circuited due to the same voltage at both ends; Keep the coil (S-ground) continuously adsorbing the iron core at the designated position;

3.Until the ignition switch is turned off, the holding coil (S-ground) and the suction coil (S-M) are powered by the M-terminal. At this time, the magnetic field generated by the suction coil (S-M) is opposite to that of the holding coil (S-ground) when it was just started, and the force of the two magnetic fields causes the iron core to return to its position, and the main contact B is disconnected from M. The circuit of the DC motor is cut off and slows down to a stop.
A starter motor, also known as a motor, converts the electrical energy of a battery into mechanical energy, driving the engine flywheel to rotate and start the engine. Starters are divided into DC electric starters, gasoline starters, compressed air starters, etc. according to their working principles. Starters can also be classified by style, such as ND starter, Bosch starter, etc. They can also be classified by vehicle type, such as Toyota starters, Cat starters, etc. An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc.
The starter can convert the electrical energy of the battery into mechanical energy, driving the engine flywheel to rotate and start the engine. The car starter mainly consists of three parts: a DC motor, a transmission meshing mechanism (shift fork, one-way clutch and drive gear), and an electromagnetic switch. During operation, the electromagnetic switch pulls and disengages the drive gear with the engine flywheel ring gear, while closing the switch contacts. The DC motor is energized and starts to rotate.
Yixing Company mainly produces starter motors and alternators, as well as ND starters, Bosch starters, and generators. The products that are suitable for car models include Toyota starters, cat starters, and other products. There are 18 major categories of products that are suitable for engineering machinery, heavy-duty trucks, commercial vehicles, small cars, motorcycles, and cruise ships.
