Working principle of starter motor
2026-01-27
The ignition switch is turned on to the starting gear, and a small current triggers the attraction/holding coil of the electromagnetic switch. The armature drives the shift fork to push the driving gear out and mesh with the flywheel ring gear.
At the moment of gear meshing, the electromagnetic switch is connected to the main circuit, the high current of the battery is input to the DC motor, and the armature rotates to output torque.
The torque is transmitted to the flywheel through the one-way clutch and driving gear, driving the crankshaft to rotate. The engine reaches the starting speed and ignites for operation.
After the engine starts, if the speed exceeds that of the starter, the one-way clutch will slip to prevent reverse drag; Release the ignition switch, turn off the electromagnetic switch, and return the shift fork to disengage the gears.
