A busbar () has a plurality of straight portions () circumferentially arranged at intervals. Several such busbars () are tied at a plurality of circumferential spaced positions by connecting the straight positions () in parallel with one another. The, the busbars () can be positioned with high precision and will not be circumferentially displaced from each other. This can avoid the deviation of intervals between the tabs () and those between terminals () from correct ones.

Central power distributing member for a brushless motor, a brushless motor provided therewith and a method of assembling it

A collection-distribution ring comprises three busbars, each having a circular ring shape, which are integrally connected together with prescribed distances therebetween by an insulating resin. Coil connection terminals project inwardly in a radial direction and are alternately arranged in relation to the three busbars. External terminals project outwardly in the radial direction and are arranged to adjoin together at the prescribed position. These terminals are all exposed from surfaces of the insulating resin. A stator comprises the prescribed number of stator units that are arranged in a circumferential direction and are assembled together with the collection-distribution ring. Each stator unit comprises a core unit realizing magnetic teeth, an insulating member, and a coil. An outer terminal member electrically connects a first end of the coil and the coil connection terminal, and an inner terminal member provides electrical connections between second ends of the adjacent coils.

A permanent magnet type rotor comprises an inner memberhaving an outer ring portion; an approximately annular outer memberhaving soft magnetism and an inner circumference contacting with an outer circumference of the outer ring portion; and plural permanent magnetsdisposed at equal intervals on the outer circumference of the outer member toward the circumferential direction. At least one of the inner memberand the outer memberis made from a sintered material, and the inner memberand the outer memberare mutually sintered and bonded. Thickness and weight of a dynamotor itself can be reduced and high output and high efficiency can be achieved.

An interconnection assembly has phase parts for U phase, V phase and W phase. The phase parts each are of a plurality of interconnection assembly parts that are connected in the form of a ring and include a conductor section to which a motor coil wire is connected, the conductor section being formed by stripping fluororesin insulation at a predetermined position, and the phase parts are partially fixedly bundled.
