Abstract
The invention pertains to electrical machines of the electromagnetic type employing a stator and a rotatable such as electrical motors and generators, wherein magnetic forces imposed upon the rotor produce rotor rotation. Permanent magnets in either the stator or the rotor assembly are used to control the magnetic flux flow through the rotor in a radial direction, and the construction of the rotor and stator utilize poles which control the forces imposed upon the rotor such that the magnetic forces on the rotor primarily drive the rotor in its working direction, and counter-rotative forces which are common with conventional electrical machines are substantially eliminated by the utilization of flux directional control. Flux movement through the rotor is in a radial direction and high efficiencies and motor control are achieved.
