PROBLEM TO BE SOLVED: To improve output and to perform efficient operation over a wide range in a torque-rotational frequency property in a magnetless rotary electric machine and a rotary electric machine drive system including the same.SOLUTION: A magnetless rotary electric machine 10 is configured by providing rotor salient poles around which rotor coils are wound, at an outer circumferential side and an inner circumferential side of an annular rotor 12, disposing an outer stator 14 at the outer circumferential side of the annular rotor 12 and an inner stator 16 at the inner circumferential side, and including two rectification elements for determining a direction of an induction current that flows to the rotor coils. Thus, the annular rotor 12 generates torque between the outer stators 14 and between the inner stators 16. A total number of outer salient poles 22 and a total number of inner salient poles 26 in the annular rotor 12 are made different, and properties of an outer rotary electric machine part 13 in using the outer stators and properties of an inner rotary electric machine part 15 in using the inner stators are made different.SELECTED DRAWING: Figure 1 |
