PROBLEM TO BE SOLVED: To provide a stator structure of a brushless DC motor, which can reduce the number of components of the stator of the motor, reducing the thickness of the stator of the motor as a whole and which can simplify the structure of the stator of the motor as a whole. SOLUTION: The stator structure of the brushless DC motor includes a single magnetic conduction piece, a coil and a drive member. The conduction piece includes a pole-piece main element, an axial hole and a plurality of pole faces. The main element has a base seat, with the axial hole opened at its center, an axial tube extending from the edge of the hole in such a manner that the pole face is formed to surround the hole, and at least one fixed hole is opened at the piece. The drive member is coupled to the piece, and the coil is provided at an annular side, formed near each of a plurality of the pole faces. COPYRIGHT: (C)2004,JPO |
