Starter Motor

Parts

  • Pinions Gear (clutch)
  • Armature
  • Solenoid (Contacts)
  • Plunger
  • Leaver
  • Field windings (pole shoes)
Functions
  • The pinions gear connects the motor to the fly wheel
  • Soleniod  pulls the plunger back using a magnetic field
  • The plunger is connected to the engagement lever. If the solenoid is activated the plunger is pulled back pulling the lever back and that pushes the pinion gear forward so that it engages to the fly wheel. The plunger also acts as a switch, when it pulls back it connect the power to the motor.
  • The field winding creates a magnetic field the interacts with the armature
  • The armature is the pole piece for the magnet, it directs the magnetic fields toward the field windings
