PROBLEM TO BE SOLVED: To provide a magnetless rotary electric machine which prevents a coil from separating from a rotor salient pole, and preferably achieves further output improvement.SOLUTION: A magnetless rotary electric machine 10 comprises an outer side stator 12, and an annular rotor 16 arranged between the inner side stator 14 and the outer side stator. The annular rotor 16 is provided with a plurality of pairs of outer and inner salient poles 42, 44 along the peripheral direction of an annular rotor yoke part 40, and a rotor coil 46 is wound crosswise between the inner peripheral surface of the rotor yoke part on one side and the outer peripheral surface of the rotor yoke part on the other side in the peripheral direction with the pair of outer and inner salient poles 42, 44 held therebetween. Rectifier elements 50, 51 are configured so that the pole polarity of the outer salient pole 42 magnetized with an induction current of the rotor coil 46 with magnetization between the outer side stator 12 and the inner side stator 14 and the pole polarity of the inner salient pole 44 have mutually-reverse polarities, and the NS directions of the polarities of the pair of adjacent outer and inner salient poles have mutually-reverse directions.SELECTED DRAWING: Figure 1 |
