PROBLEM TO BE SOLVED: To prevent the occurrence of cogging and reduce torque at high speed, by relatively shifting a control cylindrical member arranged between a permanent magnet member and a stator core to the stator core. ;SOLUTION: This motor generator is equipped with a control cylindrical member 7, where a permeable part 17 and a nonpermeable part 27 attached rotatably to a housing 1 capable of relative rotation to the inside periphery side of a stator 4 are arranged in the order in circumferential form, and a stepping motor 8 which relatively shifts the control cylindrical member 7 with respect to the stator 4, according to a rotor 3. When stopping it, the permeable part 17 of the control cylindrical member 7 is shifted to the center of the gap of the stator core 4, and it is positioned in bridging condition with respect to the teeth of a stator core 15, and the magnetic force from a permanent magnet member 5 is made to flow equally in the circumferential direction of the stator 4 to prevent the occurrence of cogging.;COPYRIGHT: (C)2000,JPO
