Title: MAGNETLESS ROTARY ELECTRIC MACHINE
Abstract:
The magnetless rotary electric machine includes an annular rotor, an outer stator and an inner stator. The annular rotor includes an annular rotor yoke portion, outer salient poles, outer rotor coils, inner salient poles, inner rotor coils, first rectifying devices and second rectifying devices. The first salient pole is configured to be magnetized by an induction current induced by the first coil. Each of the first rectifying devices is configured to rectify current such that a direction of a magnetic pole of the first salient pole is a first direction. The second salient pole is configured to be magnetized by an induction current induced by the second coil. Each of the second rectifying devices is configured to rectify current such that an direction of a magnetic pole of the second salient pole is a second direction. The second direction is a reverse direction to the first direction.
