ABSTRACT:
An n-phase electronically commutated motor has a stator with n angularly displaced phase windings, each of which comprises a pair of power windings, and each power winding is connected in series with a transistor power switch across an electric power source so that the power windings of each phase generate magnetic fluxes in opposite directions and operate in push-pull. A capacitive rotor sensor coupled to the motor rotor derives n-phase square wave rotor position signals displaced 360
degrees apart at a frequency proportional to rotor speed and n sets of logic gates receive the rotor position signals and control the conduction interval of the power transistors. The logic gates are opened during rotor position signals which energize the power switches in a sequence that generates a rotating magnetic field within the stator.
