Abstract
A single field rotor motor comprising a rotor mounted for rotation with respect to a stator. The stator has a plurality of stator poles each having a coil for creating a magnetic pole force. The rotor has a plurality of circumferentially spaced salient rotor poles formed thereon, and has a first axial end and a second axial end. Magnetic means are provided for creating an unchanging, single polarity field on all of the rotor poles by inducing flux into the axial ends of the rotor. Circuit means for alternately charge said stator coils to alternate the polarity of a given stator pole to alternately attract and repel said rotor poles to produce rotation of said rotor.
