Abstract
A collecting and distributing ring is constituted of three annular busbars a nd integrally connected with an insulation resin at predetermined distances. Co il connection terminals project radially outward and are alternately disposed i n relation with the three busbars. External terminals project radially outward and are adjacently disposed in position. All these terminals are exposed fro m the surface of the insulation resin. The stator is constituted of a predetermined number of stator units disposed circumferentially and built in the collecting and distributing ring. Each stator unit comprises a core unit for realizing magnetic teeth, insulation members, and coils. The first end o f a coil is connected to a coil connection terminal by an external terminal member, and the second ends of adjacent coils are electrically connected by an internal terminal member.
