Description
The Permanent Magnet Gear Reduction (PG200 and PG250) starter motors feature small
permanent magnets mounted inside the field frame (NOTE: The actual configuration of
these magnets differs between the PG200, PG250 and PG260; the field frames with
permanent magnets are not interchangeable. Otherwise, the units are similar.) These
magnets take the place of current-carrying field coils mounted on iron pole pieces. Internal
gear reduction, approximately 4 to 1, through planetary gears results in armature speeds
in the 7000 rpm range. The armature and drive shaft are mounted on roller or ball bearings
in place of bushings. The solenoid switch, plunger, return spring, and shift lever are
permanently mounted in the drive housing.
CAUTION
The starter motor is designed to operate under great overload and produce a high
horsepower for its size. It can do this only for a short time, since considerable heat
accumulates and can cause serious damage. For this reason, the cranking motor
must never be used for more than 30 seconds at any one time. Cranking should not
be repeated without a pause of at least 2 minutes to permit the heat to escape.
