This diagram illustrates the primary components of an automobile starter motor, which converts electrical energy from the battery into mechanical energy to rotate the engine's flywheel.Solenoid: This electromagnetic component acts as a heavy-duty switch, activating the starter by pushing the pinion gear forward and closing the circuit to supply power to the motor.Bendix Drive: A mechanism located on the end of the starter shaft that engages the pinion gear with the engine's flywheel to crank the engine.Motor: The electric motor consists of an armature and field coils that generate the rotational force necessary to turn the engine.Brushes and Terminals: Brushes transfer electrical current to the rotating armature, while the B+ terminal receives high amperage from the battery and the GND terminal provides the ground connection.
