<p>PROBLEM TO BE SOLVED: To ensure an electric continuity passage in grounding a stator core by fitting a stator core onto a cylindrical stator bush which is fitted onto the cylindrical outer periphery of a stationary member, and covering an external surface other than the outer periphery of the stator core with an insulation coating layer for winding a coil. SOLUTION: A stator core 19 is fitted onto a cylindrical stator bush 18 which is fitted onto the cylindrical outer periphery of a fixed shaft (stationary member) 1, and an external surface other than the outer periphery of the stator core 19 is covered with an insulation coating layer 21 to wind a coil 22. To facilitate fitting work by inserting the stator core 19 from one end part of a stator bush 18, it is preferable that the outside diameter of one end part of the stator bush 18 is formed so as to be a little smaller. It is thus possible to ensure an electric continuity passage completely in grounding the stator core 19 and prevent generation of breaking in a crossover effectively.</p> |
