Abstract
A combination of a unique construction format, involving two sets of rotor and stator embodiments, working in co-operation with each other, in a unique fixed, direct-axis and quadrature-axis orientation, and with unique field-winding, back-EMF cancellation, connection schemes to substantially negate the field-winding harmonic currents in the field-winding excitation circuits, and provide for a substantially square-wave shaped, open-terminal, armature output-voltage characteristic.
