Starter Motor
The starter motor now used in automobiles incorporates a magnetic switch that shifts a rotating gear (Called a pinion gear) into and out of mesh with the ring gear around the circumference of the flywheel, Which is bolted to the engine crankshaft. There are at present two major types of starter motor used on cars and smaller trucks: Conventional and reduction. Automobiles designed for use in cold regions use the reduction type starter motor, Which generates the greater torque required to start the engine at low temperatures. Scince it is capable of generating a much greater torque, in proportion to size and weight, Then the conventional one, More automobiles are now coming to use this type even in warmer regions.
Generally, A starter motor is rated by its nominal output (In KW) - The greater the output, The greater the starting capability.
As automobiles generally use 12V batteries, Starter motors are designed for this voltage. Some diesel-powered vehicles, However, Use two 12V batteries connected in series (12V + 12V = 24V) and a 24V starter motor to boost starting performance. The construction, Operation and troubleshooting procedures for the 24V starter motor are essentially the same as those for the 12V versions.
