PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of improving output characteristics and efficiency of a motor at low- and high-speed operation. SOLUTION: The rotary electric machine has a stator 6, a rotor 4 provided coaxially and freely rotatably with the stator, and stator moving means 11, 12 for changing the relative position of the stator in a rotor's axial A line direction for the rotor. The stator is provided with an armature coil 9 and a core 6a having the armature coil wound therearound, and the other part is provided with a magnet 5 so as to oppose the core. The core continuously has two or more members having different magnetic characteristics along the axial line A, and a low iron loss member is provided on the core 6a on a side opposite to a direction where the stator is moved in the axial direction by the stator 6 moving means 11, 12 so that an area between a magnetic pole surface 5a of the magnet 5 and an opposite surface of the core opposing the magnetic pole surface 5a may become small.
