Abstract:
1. A parallel pole direct drive motor comprising: an outside rotor having a circular rotor disc with a ring of plural magnets with alternating polarities flush mounted into plural holes around a circumference of the circular rotor disc a distance from an outer edge of the circular rotor disc; an inside stator assembly having a ring of wound magnetic flux channel pole pieces corresponding to a phase of the motor attached with a bobbin housing a transversely wound stator winding to capture and focus the magnetic flux emanating from the transverse winding and channel the magnetic flux to the ring of wound magnetic flux channel pole pieces, each pole piece body having au-shaped gap on the radial outer side of the bobbin to form a magnetic flux channel to receive the circular rotor disc with flush mounted ring of magnets in the formed magnetic flux channel to direct and focus the captured magnetic flux toward and delivering the captured magnetic flux to the ring of plural flush mounted magnets in the formed magnetic flux channel, perpendicular magnetic lines of force emanating at a surface of each wound magnetic flux channel pole piece; and a controller coupled with a feedback electronics for monitoring a timing, speed and direction and coupling the feedback signal to a processing unit for determining and adjusting and drive electronics.
