ELECTRICAL 30 CONSTRUCTION: The Construction of the Starter Motor is as follows ARMATURE ASSEMBLY: 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. FIXING BRACKET ASSEMBLY: Aluminum die casting with Sintered Bearing Bush offers longer bearing life. YOKE ASSEMBLY: Deep drawn yoke with Permanent magnet. BRUSH GEAR ASSEMBLY: Epoxy glass filled laminates for high temperature, Rivet less BG operation. SOLENOID SWITCH: Internal body and terminal cover moulding with built – in engagement spring. DRIVE SHAFT & INTERNAL GEAR ASSEMBLY: 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.
