Abstract
The invention pertains to electrical machines of the electromagnetic type employing a stator and a rotatable rotor such as electric motors and generators wherein magnetic forces imposed upon the rotor produce rotor rotation. The invention utilizes permanent magnets in either the stator or rotor assembly to control the magnetic flux flow in one direction and encourage the flux in the opposite direction in certain areas of the stator and rotor assembly. Rotating flux conducting metal shunts are disposed adjacent permanent magnets creating magnetic flux to control the flux flow and pattern to most effectively use the flux forces on the rotor resulting in very high efficiencies in motor or generator operation.
Claims4
The method of operating an electric motor having a rotatable rotor having ferrite poles located within a stator core made of alternately oriented permanent magnet poles or, a stator core properly incorporating alternately oriented permanent magnet poles wherein the stator core includes a coil and a positive current phase and magnetomechanical flux circuit forces between the rotor and stator in the rotor interaction area rotate the rotor in a first direction about an axis comprising inducing a spinning magnetic field in the rotor interaction area of the stator core to act on the rotatable rotor so that the permanent magnets sort the electromagnetic flux from the stator core's positive-current phase so that the electromagnetically created flux in the stator is induced to set up flux circuits through every other magnet-pole of the stator and is inhibited in setting flux circuits in the remaining magnet-poles of the stator, and upon the stator coil reversing to the negative current phase, the magnet-poles induce the oppositely oriented stator coil flux to set up flux circuits in the poles they previously inhibited in the positive phase and inhibits the stator coil flux from setting up flux circuits in the magnet-poles in which they induced flux circuits in the positive phase.
