<p>PROBLEM TO BE SOLVED: To provide a rotary electric machine that can rotate in a high-speed and can output high torque in a low-speed rotation region.SOLUTION: A rotary electric machine 1 comprises: a magnetic flux supply body 41 relatively rotatably supported by a rotation shaft 21, and having an auxiliary magnet 44 spaced from an output rotor 4 inward in a radial direction; a small motor 42 rotating integrally with the output rotor 4; and a worm gear 54 rotary-driven by the small motor 42 and meshed with a tooth part 48 formed on a supporting member 45 of the magnetic flux supply body 41. Then, by transmitting rotation of the small motor 42 to the support member 45, a relative rotation angle of the magnetic flux supply body 41 is adjusted between a weak angle at which a polarity of a rotor magnetic pole part 36 of a rotor core 22 is opposite to a polarity of a magnetic pole of a supply body magnetic pole part 50 opposed to the rotor magnetic pole part 36 in a radial direction, and a strong angle at which the polarity of the rotor magnetic pole part 36 of the rotor core 22 is identical to the polarity of the magnetic pole of the supply body magnetic pole part 50 opposed to the rotor magnetic pole part 36 in the radial direction.</p> |
