PROBLEM TO BE SOLVED: To provide a dynamo-electric machine which can be downsized more as a whole. SOLUTION: In the dynamo-electric machine which has a rotor where a magnet is mounted on a rotor core where a rotating shaft pierces the center of the surface of a board and a stator where stator winding is wound on the stator teeth of the rotor core and the rotor is held rotatably, having an air gap between itself and the stator, the annular discoidal back core part 20 of the stator core 14 is made such that the center of the board face and the peripheral margin of the board face are different in thickness in the axial direction of the rotating shaft 16. A plurality of stator teeth parts 21 are protruded each apart on the incline 20b of the stator back core part 20, being arranged aslant to the rotating shaft 16. COPYRIGHT: (C)2006,JPO&NCIPI
