Abstract: Iron rings and radially polarized magnets are alternated with axially magnetized rings on both a rotor and a stator in which like poles of axial magnets on and between the rotor and stator face one another to produce a field within the air gap between the magnets equivalent to that produced by radially magnetized magnets, to redistribute flux within the air gap, to smooth out non-uniformity of individual magnetic flux distributions, to provide repulsion between the stator and the rotor, to minimize energy losses due to rotor rotation, to produce a uniform field in the air gap despite non-uniformity in the magnets, to reduce spin drag torques due to non-uniform magnetization to near zero value, to maximize the flux collection effectiveness of the iron rings, to fill the entire volume with a useful material, and to obtain a more intense field in the air gap, thereby providing a weight effective structure.
