1 Armature

It is an electromagnet component used as a guide on the driveshaft or bearings. The armature contains a laminated soft iron core that has been wound or looped with numerous conductors.

2 Commutator

It is the portion of the shaft that brushes run along to conduct electricity that is located at the back of the housing. The commutator is built from two plates mounted to the armature’s axle and connects the electromagnet’s coil.

3 Solenoid
The solenoid has two wire coils wrapped around the core. This solenoid acts as a switch, connecting and disconnecting the electrical connection between the starter motor and the vehicle’s battery.

4 Brushes
A series of brushes are used to transfer electrical current from a static conductor to a dynamic conductor. The brushes make contact with the commutator. Brushes conduct electricity as they rub the commutator.

5 Plunger
In a starter motor, a plunger has the function of pushing forward so that the pinion can be engaged, which in turn starts the motor.

6 Lever Fork
A lever fork is attached to a plunger, and when the lever fork is pushed forward together with the plunger, the pinion is engaged.

7 Pinion
A pinion is a device that has a gear and springs inside. It engages immediately after starting the engine by extending the gear to the flywheel teeth.

8 Field Coils
The field coils consist of two or more coils connected in series and are secured in the housing by screws. The battery provides power to these coils, turning them into an electromagnet that rotates the armature. As a result, a magnetic field develops around the armature.
