  • Patent number: 11482914
    Abstract: A rotary electric machine includes a rotor in which a plurality of permanent magnets are disposed along a rotation circumference and in which a magnetic pole of the permanent magnet is directed in a direction along a rotational axis and a stator in which a plurality of windings are disposed along the rotation circumference in a direction in which the magnetic pole of the permanent magnet is directed. The stator is formed in a direction in which a magnetic path from an end of the stator to an inside of the stator intersects a main magnetic flux direction from the rotor when the rotor is directed toward ends of first to four windings. A plurality of stators, provided along the rotational axis of the rotor, are respectively placed at positions at which gaps between the windings deviate from each other in a rotation circumference direction.
