To provide a rotary electric machine that has higher efficiency, and higher torque, achieved in an inexpensive and reliable method.
A stator 100 has a stator core 1 and concentrated windings 4. The stator core 1 has: an annular yoke section; and n winding poles that extend radially from the annular yoke section. The concentrated windings 4 are wound around the winding poles. The stator core 1 is divided into two segments in a direction of a rotating shaft 10, and is further divided into n segments in a circumferential direction. A rotor 200 has: a permanent magnet 8 that is magnetized in the direction of the rotating shaft 10; and two rotor cores 7 that sandwich the permanent magnet 8 therebetween. Circumferences of the winding poles of the stator 100 face circumferences of the rotor cores 7 through air gaps. End surfaces of the winding poles of the stator 100 face end surfaces of the rotor cores 7 through air gaps. Thus, a rotary electric machine has both radial gaps and axial gaps.
