ABSTRACT:
An electro-mechanical device that functions as a motor or a generator and methods for constructing and using such electro-mechanical device are provided. The electro-mechanical device features permanent magnets placed in a magnetically attracting manner and inter-dispersed between control coils. The control coils are energized to create a flux opposing the flux of the permanent magnets and to create a rotational torque on the poles of a salient pole rotor before those poles align with the poles of the energized control coil stator segment. Power can be generated by placing the flux of the control coils in a steady state and mechanically rotating the salient pole rotor. The electro-mechanical device provides little or no cogging forces, high-efficiency operation, and a high power density.
