Abstract: A busbar (10) has a plurality of straight portions (14) circumferentially arranged at intervals. Several such busbars (10) are tied at a plurality of circumferential spaced positions by connecting the straight positions (14) in parallel with one another. The, the busbars (10) 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 (16) and those between terminals (18) from correct ones.

Abstract: To produce bus bars, a conductive metal plate is stamped out into a plurality of strips simultaneously by press molding. Each strip has a tab having an L-shaped cross-section defined by a curved section and a distal end. The plurality of strips are bent in a thickness direction to obtain a plurality of rings, respectively. The rings are mutually different in diameter and have substantially the same center. The L-shaped tab of each of the rings is disposed such that the distal end of each tab is disposed substantially at a same distance from the center.

Abstract: 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.

Abstract: A stator for use in a rotating electrical machine is constituted by arranging the prescribed number of stator units in the circumferential direction of a stator core having a circular ring shape. The stator units provide magnetic teeth that project inwardly in the radial direction of the stator core. Coils are wound about the magnetic teeth via insulating members. Each of the insulating members arranges thick portions that slightly project opposite to each other in the width direction of the magnetic tooth, wherein the thick portions are shifted in positions in the thickness direction of the stator core with respect to opposite sides of the magnetic teeth arranged opposite to each other. Thus, it is possible to noticeably improve the space factor in the stator.
