Parts of a starter motor:🚘🚗
- Starter Solenoid: An electromagnetic switch that engages the starter motor. It receives a signal from the ignition switch and then closes a high-current circuit to power the starter motor.
- Battery Cable Terminal: The connection point where the cable from the battery attaches to the starter motor, providing the necessary electrical power.
- Starter Control Terminal: Receives the signal from the ignition switch to activate the solenoid.
- Starter Gear: A small gear that extends to engage with the engine's flywheel, turning the engine over during starting.
- Starter Motor: An electric motor that provides the mechanical force to turn the engine over for starting.
- Drive End Bracket: A support structure that houses and protects the end of the starter motor.
- Solenoid: A smaller, separate solenoid can also refer to the component that moves the starter gear into engagement with the flywheel.
- Bendix-Drive: A mechanism that allows the starter gear to engage and disengage from the engine flywheel.
- DE Bush (Drive End Bushing): A bushing located in the drive end bracket that supports the armature shaft.
- Fork: Connects the solenoid to the Bendix drive, pushing the Bendix drive forward to engage the flywheel when the solenoid is energized.
- Armature: The rotating part of the starter motor, containing the windings that create the magnetic field and generate the torque.
- Dust Cover: A protective cover that prevents dirt and debris from entering the starter motor.
- CE Bush (Commutator End Bushing): A bushing located at the commutator end of the starter motor, supporting the armature shaft.
- Yoke: The frame that provides structural support for the field coils and focuses the magnetic field.
- Field Coils: Windings of wire that create a magnetic field when current passes through them, interacting with the armature to produce torque.
- Brush Holder: Holds the brushes in place, allowing them to make contact with the commutator.
- Comm Dn Bracket (Commutator End Bracket): A bracket that supports the commutator end of the starter motor and houses the CE bushing.
