Study Notes

Armature Core

Holds windings in place, made of iron to enhance magnetic field strength.

12 Volt Starting System

Components include battery, ignition switch, wires, starter motor, solenoid, Bendix drive, flywheel.

Commutator

Composed of insulated metal strips or bars, flips electrical flow, ensuring alternating current flow.

Engine Starting System

Similar to 12 Volt Starting System with additional components such as ECM (Engine Control Module) in some cases.

Field Windings

Large insulated stationary wires wrapped around pole shoes to aid in magnetic field generation.

Ignition Switch

Operates the solenoid, closing the circuit to engage the starter motor.

Magnetic Field

Defined as the area around a magnet that exerts magnetic force.

Neutral Safety Switch

Ensures engine does not crank unless transmission is in neutral or park position for safety.

Overrunning Clutch

Locks pinion gear in one direction while allowing it to release in the opposite direction.

Starting Motor

Transforms electrical energy from the battery into mechanical energy to successfully crank the engine.

Starter Solenoid

An electro-mechanical device that engages the pinion gear with the engine's flywheel or drive plate.

Starter Relay

Controls the high-voltage circuit connecting to the starter, opening or closing as needed.

Solenoid Disc

Completes the battery-to-starter circuit by contacting both high-current terminals.

Gear Reduction Starter

Specifically designed to crank high compression engines or diesel engines effectively.

Pole Shoes

Essential components that create a magnetic field to amplify magnetism between them.

Pinion Gear

A small gear on the armature shaft that engages with the larger ring gear of the engine flywheel.

Permanent Magnet

Made of ferromagnetic material capable of maintaining aligned magnetic domains for permanent magnetism.

Starter Actuated Solenoid

Features a plunger that activates a shift lever to connect with the pinion gear, facilitating engagement.

Starter Armature

Comprised of the armature shaft, core, commutator, and armature windings, integral to motor function.

Solenoid Windings

When the ignition key is turned to start, a small current flows through this, creating a magnetic field that engages the solenoid and completes the circuit to the starter.
