Study Notes
Action of Starter
- A conductor carrying current placed in a magnetic field experiences attractive forces between opposite fields and repulsive forces between similar fields.
- The direction of the magnetic field around the conductor can be determined using the right-hand rule.
- The conductor moves from regions of stronger magnetic fields to weaker ones, resulting in the movement of the armature shaft.
Starter Action
- Turning on the ignition switch initiates current flow to the field winding of the starter, which strengthens the magnetic field.
- Further action of the ignition switch allows current to flow to the armature through carbon brushes, creating a repulsive force that moves the armature shaft.
- Current initially flows to the solenoid assembly, magnetizing the pulling winding.
- The energized solenoid pulls itself towards the winding, causing the yoke to move the fork, which meshes the starter pinion with the teeth of the flywheel.
- As a result, the movement of the armature shaft transfers drive to the flywheel, cranking the engine.
