Gated permanent magnet motor

Claim 1

A gated permanent magnet motor wherein 50 percent of the required force to do a specific amount of work is derived from the peak energy product of the permanent magnets, said motor comprising fore and aft stator sections, comprising at least four hybrid annular stator poles per section, said stator poles consisting of seven segmented annular permanent magnets joined with a high permeability iron core of equal diameter and fitted with an annular coil to form a series hybrid magnetic pole, said stator poles are distributed circumferentially at opposite ends within the motor casing at 90* intervals with the pole end bearing the coil, placed opposite each other, but separated by an appropriate distance to receive a rotor comprising a non-magnetic hub having four radially extending spokes, spaced at an interval of 90* with means to support four stacks of annular permanent rotor poles having their longitudinal axis orthogonal to the path of rotation, said magnets being identical with the stator magnets but containing only five segments per pole, a shaft extending through and beyond the fore and aft motor bearing and having means to retain and lock the rotor and rotor poles in a precise axial and radial alignment with the stator poles, said rotor is made rotatable on the said shaft between the fore and aft stator poles either in a clockwise or counter clockwise rotation, said shaft having means to receive and retain a cylindrical shaped gating module comprising a high temperature, high strength plastic core locked in a synchronized position by mechanical means on the aft end of the rotor shaft in a corotational alignment with the rotor poles such that the leading edge of the positive gating segments lead the leading edge of the rotor poles by 45*, while the leading edge of the negative gating segments trailing the positive gating segments by 22.5* and are in a precise corotation alignment with the leading edge of the rotor poles, said core being inlaid with copper slip rings on both ends, said slip rings having inwardly projecting conducting segments alternately interlaced aroung the periphery of the cylinder with eight conducting and eight non conducting segments, said slip rings driven by the rotation of the shaft are in constant contact with positively and negatively energized brushes located 213 degrees in a clockwise direction and held there in a brush holder, means for coupling and controlling a source of alternate half cycle or DC voltage input continuously during the operation phase, at least four gating brushes circumferentially distributed at an equidistance of 90* around the periphery of the gating module and held in a precise position in their respective brush holders such that the leading edge of each brush is in a tangental position at 22.5* past the center angle of their respective stator poles, said brushes are alternately and simultaneously energized and electrically connected to an axially opposite pair of gating coils, with each 42* of rotation of the gating module, all eight gating coils are positively excited off for 3*, then negatively excited for 42* of rotation, then again off for another 3*; this process of on and off gating is repeated eight times for each revolution of the rotor, the continuous and sequential on and off gating of the said gating coils produces a reciprocal polarity reversal in the stator magnetic field such as to rotatively drive the said permanent magnet rotor.
