PROBLEM TO BE SOLVED: To provide a stator structure having high reliability that is configured to have an unfilled space portion of heat radiating resin material between a heat-radiating resin material and an electrical connection portion while efficiently radiating heat generated in a winding body.SOLUTION: A stator intermediate assembly includes a stator having a stator core 1, an insulator 2 and a wound body 3, and a printed circuit board 5. The stator intermediate assembly is arranged on one side in the axial direction on the printed circuit board 5, and all of a connection wire end portion of a connecting portion of the wound body 3, a connecting wire end portion of the winding body 3 to be connected to the connector 6 and a connection wire of the wound body 3 to be connected to the printed circuit board 5 are wired on the arrangement side of the printed circuit board 5. The printed circuit board 5 is configured to be annular, fan-shaped or the like, and has a hollow portion at the center. The output shafts of the rotor and the motor are loosely inserted in the hollow portion. An open end of a stator frame 4 is set at the upper side, and a shaft hole of the stator frame 4 is set at the lower side.SELECTED DRAWING: Figure 4
