PROBLEM TO BE SOLVED: To provide a rotary electric machine capable suppressing noise vibration than before by suppressing harmonic content to a low level, without requiring a separate circuit element such as a capacitor.SOLUTION: A rotary electric machine 10 includes a stator 12 in which a plurality of slots 12s are arranged to respectively face a magnet body 14, and a rotor 11 provided with at least one magnet body 14 which is rotatably arranged through a gap G and embedded in an iron core. In the magnet body 14, a plurality of magnets are stacked in the direction of rotational axis. Assuming that a slot multiple representing a ratio of the slot 12s against the magnet body 14 is S, a slot pitch which is an angle between the slots 12s is α (degree), arc ratio which is an angle representing a range through which a magnetic flux flows radially from the magnet body 14 is &thetas;a (degree), and a skew angle representing a deviation angle between magnets contained in the magnet body 14 is &thetas;s (degree), then a skew angle is set so as to satisfy &thetas;s=kα/2 (where k is coefficient). |
