7. CONSTRUCTION
The Construction of the Starter Motor is as follows :
ARMATUREASSEMBLY :
Moulded commutator high
speed operation two part
epoxy varnish impregnation
for high fling resistance.
Dynamically balanced
Armature for less noise and
longer bearing life. Welded
joint for Armature conductors
for enhanced thermal rating.
YOKEASSEMBLY
:
Deep drawn yoke with
permanent magnet.
BRUSHGEARASSEMBLY :
Epoxy glass filled laminates
for high temperature, Rivet
less BG operation.
FIXINGBRACKETASSEMBLY :
Aluminum die casting with
Sintered Bearing Bush offers
longer bearing life.
CEBRACKET :
Aluminum die casting with
Sintered Bearing Bush to
support for armature assy.
SOLENOID SWITCH :
Internal body and terminal
cover moulding with built - in
engagement spring.
DRIVE SHAFT & INTERNALGEARASSEMBLY :
1. Gear shaft:
Steel forged heat -
treated
shaft with helix to house the
drive
2. Planetary Gear:
Sintered gears with sintered
bush bearing consistent
dimensional control.
3. Internal Gear:
Plastic gear (GF45) WITH
Sintered Bearing, bearing for
increased output.
4. Over running clutch
sleeve:
Extruded heat– treated steel
helical spline for drive.
