ROTARY ELECTRIC MACHINE INTEGRAL WITH MAGNETIC TRANSMISSION

Japanese Patent JP2021118614

A

To provide a rotary electric machine integral with a magnetic transmission that can reduce cogging torque.SOLUTION: A rotary electric machine 10 comprises: a first magnet magnetic pole 20 having a plurality of first magnet magnetic poles 21 and 22; a second magnet magnetic pole 30 having a plurality of second magnet magnetic poles 31 and 32; a modulator 40 provided between the first magnet magnetic pole 20 and the second magnet magnetic pole 30 and having a plurality of magnetic pole pieces 41; and a stator 50 having a coil 51 which interacts with the first magnet magnetic pole 20. A stator 50, the first magnet magnetic pole 20, the modulator 40, and the second magnet magnetic pole 30 are arranged coaxially. A stable point of a stator-side magnetic force is positioned being offset from a stable point of a modulator-side magnetic force such that "a cogging torque Tc
