PURPOSE: To improve the structure of a brushless flux controlled motor- generator, which controls the magnitude of the magnetic flux for linking a rotor and a stator by the control of a coil current and variably controls the relationship between the number of revolutions and torque. CONSTITUTION: Magnets 82a and 82b are magnetically attached to the outer surface of stacked rotor laminations and form one of rotor poles. A main magnetic-flux open path for linking a rotor assembly and a stator assembly is constituted. A coil 70, which controls the magnetic flux of the main magnetic- flux path, is mounted on the end wall of a motor housing with a gap G2 being provided for a rotor shaft by a magnet attaching device 66. A magnetism conductor device, having a ring part surrounding the coil through the gap and the finger parts 82a and 82b extending from the ring part, is magnetically attached on the magnets at the finger parts. The stable mounting of the magnets on the rotor is aided, and a secondary magnetic flux path passing the coil, the rotor shaft, the magnets, the finger part and the ring part is constituted. |
