Abstract: The commutator segments for a d.c. electric motor includes one or plurality of slots which improves horsepower at less amperage.

Abstract: A multiple pole, multiple phase, permanent magnet motor comprising a rotor having a plurality of permanent magnet poles, a stator having a plurality of stator slots and an equal number of stator teeth defined by adjacent stator slots, and a plurality of phase windings disposed on the stator, each phase winding including a plurality of coils having a non-uniform number of turns, such that electromagnetic poles are developed in proximity to the stator, the electromagnetic poles for each phase being distributed symmetrically about the stator, equidistant from one another, and equal in number to the number of permanent magnet rotor poles. The number of turns of each of the plurality of coils of each phase winding is selected in accordance with a predetermined sinusoidal relation.

Abstract: In a refrigerator motor with a hollow base-housing with an open mouth defined by a side wall, and a cover for the mouth, one of the housing and cover has integral with it at least one deflectable finger, one end of which is integral with one of said cover and housing and a free end of which is provided with a lip. The other of the housing and cover has integral with it a complementary ledge, spaced and shaped to receive and to be engaged by the lip. In either case, the cover carries, preferably integral with it, a motor mounting bracket by which the motor is mounted in a refrigeration unit. In a preferred embodiment, the finger is integral with the cover and the ledge is integral with the housing, and the mounting bracket has arms that extend beyond a lower perimeter of the housing.
