PROBLEM TO BE SOLVED: To provide a dynamo-electric machine which ensures higher output efficiency, while avoiding complicating the shape. SOLUTION: This dynamo-electric machine is provided with a stator 3, to which a coil 9 is wound and a rotor 1 which is allocated coaxially to the stator 3 to rotate freely. The stator 3 is configured to individually provide a yoke portion 4 and a teeth portion 5, to which the coil 9 is wound. Length in the axial direction of the yoke portion 4 is set longer than the length in the axial direction of the teeth portion 5.
