Motor is the transliteration of English motor, namely electric motor and engine. The working principle is to drive the starter rotor to rotate through the energized coil in the magnetic field, and the pinion to drive the engine flywheel to rotate.
The electronic starter is the motor that people often say now, also called the starter. It is forced to rotate in a magnetic field through the energized coil, which drives the starter rotor to rotate, and the pinion on the rotor drives the engine flywheel to rotate, thereby driving the crankshaft to rotate. The innovation of the new low-cost spark plugs and starters of the porcelain core base has laid the technical foundation for the development of automobiles.
The working principle of the starter.
The control device of the automobile starter includes an electromagnetic switch, a start relay and an ignition start switch lamp assembly, wherein the electromagnetic switch and the starter are composed.
The working principle of the electromagnetic switch.
When the magnetic flux generated by the attracting coil and the holding coil are in the same direction, their electromagnetic attraction forces are superimposed on each other, which can attract the movable iron core to move forward until the contact disc at the front end of the push rod is connected to the main circuit of the motor.
When the magnetic flux generated by the attracting coil and the holding coil are in opposite directions, their electromagnetic attraction forces cancel each other out. Under the action of the return spring, the movable iron core and other movable parts are automatically reset, the contacts and the contacts are disconnected, and the main circuit of the motor is disconnected.
