Date Oct. 27, 1994A stator with a magnetic circuit having separate slots to accommodate coil groups of a three-phase delta- and star-connected windings. Vectors of magnetic induction of each coil group intersect an axis of the magnetic circuit. The coil groups of like phases overlap one another in a cross section of the stator and are displaced through 30 electrical degrees. The three-phase windings are made with similar power ratings. This provides substantial temporal and geometric orthogonality between pairs of vectors of one phase of one three-phase winding and the coil groups of the next phase of the other three-phase winding.
