What is the principle of the original 4-wire central control motor?

The principle of the original 4-wire central control motor is mainly to drive the starter rotor to rotate through electromagnetic induction. The small gear on the rotor drives the generator flywheel to rotate, thereby driving the crankshaft to turn and start the engine. Definition of motor: Motor is the transliteration of the English word 'motor', meaning electric motor or engine. Its working principle is that the energized coil rotates under force in a magnetic field, driving the starter rotor to rotate. The small gear on the rotor then drives the engine flywheel to rotate. The throttle motor is a component of the car air conditioning system. Function of motor: The motor is mainly used to control car idling, with the purpose of adjusting idle speed according to engine load during idling. The idle stepper motor is installed on the throttle body and is controlled by the engine controller to regulate engine idle speed. When the engine speed deviates from idle, the throttle valve adjusts and controls the amount of air entering the intake manifold, which is mechanically operated by the accelerator pedal cable. The throttle has a bypass air passage that supplies air during engine idling (when the throttle is closed). The pivot of the automatic idle motor extends into the bypass air passage to regulate air flow. The engine controller uses input signals from various sensors to move the pivot of the automatic idle motor in and out of the bypass air passage to adjust the engine idle speed. When the ignition key is turned to the 'on' position, the automatic idle motor starts working. This switch signal is input to the ECU to determine whether the engine is in idle condition. Meanwhile, the motor's current position is fed back to the ECU by the motor position sensor.
