Abstract

See full text

A permanent magnet generating system includes first and second permanent magnet generators, or PMG's each having a permanent magnet rotor structure and a stator structure. Each stator structure has at least one stator winding disposed therein and the stator windings of the PMG's are connected in series so that the voltages developed thereby add vectorially to develop a combined output voltage. The position of the stator windings of one PMG is adjustable relative to the position of the stator windings of the other PMG to vary the phase angle between the two output voltages of the PMG's so that the combined output voltage can be controlled at a desired value irrespective of changes in operating speed or load.
