  • Patent number: 5041749
    Abstract: A DC brushless motor comprising a rotor shaft, and rotor assembly mounted on the rotor shaft. The rotor assembly includes a permanent magnet rotor and a plurality of sequentially stacked rotor laminations positioned between the rotor magnet and the rotor shaft. The permanent magnet rotor is magnetized with N number of rotor poles. A stator assembly in magnetic flux relationship with the rotor assembly is provided. The stator assembly includes plurality of sequentially stacked stator laminations with each stator lamination having N number of stator poles. The stator laminations are juxtaposed to the permanent magnet rotor such that each stator pole is of a different polarity from the corresponding rotor pole. The distance between the stator and rotor poles forms an air gap. Each of the stator poles are slightly skewed with respect to each of the corresponding rotor poles such that the air gap is asymmetrical. Electrical windings are provided for energizing the stator poles to operate the rotor.
