Method of operating a sealed motor and preventing overheating

The present invention dsicloses a method of operating a sealed motor which includes a stator, a plurality of drive windings for said stator, plural Hall-effect devices for commutating said drive windings, and a magnetically transparent enclosure enclosing a rotor including plural permanent magnets therein. The method includes periodically energizing said drive windings with plural pulses of current, periodically interrupting said pulses of said current with relatively great intervals of virtually no current and periodically allowing said armature to come to a virtual stop during each of said intervals, thereby rotating said armature in increments and avoiding damaging heat build up in said sealed motor.
