Description
The starter motor has only one function which is the first and
second rotations the engine needed. Apart from that, the device is
just an extra load to the vehicle. There should be another means of
starting vehicles without starter motors right! I think the
component is too big for one function.
Parts of Starter Motor
Below are starter motors parts and their functions:
Armature:
An armature is an electromagnet component that is mounted on the
driveshaft or bearings for a guide. It is made of a laminated soft
iron core which is wrapped with numerous conductor loops or
windings.
Commutator:
A commutator is a section of the shaft at the rear of the housing
on which brushes run to conduct electricity. It is made of two
plates mounted to the axle of the armature, the plates provide
connections for the coil of the electromagnet.
Brushes:
Brushes are parts that run on a section of the commutator at the
rear of the housing. it rubs the commutator and conducts
electricity.
Solenoid:
The solenoid features two coils of wire that are wrapped around the
core. This solenoid serves as a switch that connects and close the
electrical connection between the starter motor and the vehicle’s
battery.
Plunger:
The function of a plunger in a starter motor is to push forward so
the pinion can be engaged.
Lever Fork:
The lever fork is connected to the plunger which makes them push
forward together to engage the pinion.
Pinion:
A pinion is a small mechanism containing gear and springs. It
engages immediately the engine started, by extending the gear to
the flywheel teeth. The flywheel is the source of engine rotation.
Field Coils:
The field coils are held in housing with screws as it consists of
two or more coils connected in series. These coils receive power
from the battery that converts them into an electromagnet that
turns the armature. This creates a magnetic field around the
armature.
