PROBLEM TO BE SOLVED: To provide a rotary electric machine whose axial directional dimension is small. SOLUTION: The rotary electric machine has a stator comprising an armature winding and an armature core furnished with it: and a rotor provided with first and second magnetic pole groups, in which positive and negative poles are alternately disposed in the circumferential direction at both sides of inner and outer radial surfaces or both end surfaces in the axial direction of a laminated core, respectively; and further, the magnetomotive force source of the first magnetic pole group is a permanent magnet, and the magnetomotive force source of the second magnetic pole group is an electromagnet; and the armature core passes magnetic flux by actions of the respective magnetomotive force sources through the same passage, and further winds the armature winding on the passage.
