Abstract:
1. A rotating electric machine comprising: a stator, the stator including: a rotor rotatably supported on an inner peripheral side of the stator via a gap, wherein the stator winding is divided into at least two for each phase in the slot so as to balance inductance; the stator winding of each phase is divided and inserted evenly in a radial direction or a rotating direction in the slot, the stator winding being disposed such that a value of totaling all distances for each phase, each distance being from a center of the stator core, is identical for all phases; and the stator winding of each phase has annular coils disposed at a pitch that doubles a magnetic pole pitch, and the number of annular coils is equally divided so as to be ½ of the number of poles, each of the annular coils being inserted in the slot with the magnetic pole pitch out of phase from each other before being combined through a series connection.
