Conventional Type
Construction
This type of starter motor contains a magnetic switch, Electric motor, Drive lever, Pinion gear, Starter clutch etc. The pinion gear is located on the same axis as the armature and rotates at the same speed as it. The drive lever connected to the magnetic switch plunger pushes the pinion gear and and causes it to mesh with the ring gear.
1. Magnetic switch.
The magnetic switch (Also referred to as a Solenoid) consists of a hold-in coil, Pull-in coil, A return Spring, A plunger and other components. It is activated by the magnetic forces generated in the coils and carries out the following two functions:
- It pushes the pinion gear so that it meshes with the ring gear.
- It serves as a main switch or relay, Allowing heavy current to pass from the battery to the starter motor.
