A rotational electric machine stator has a rectangular wire that includes a lead wire covered with an insulation coating, terminals that is connected to the rectangular wire by thermal fusing, and convex portions provided on the terminals so as to protrude from the terminals toward the rectangular wire, wherein the insulation coating is removed.

Rotational electric machine stator and manufacturing method therefor

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

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.

Method of producing bus bars for centralized power distribution unit

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.

Permanent magnet type rotor and method of manufacturing the rotor

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.

A centralized power distribution unit for a vehicular thin brushless motor includes a plurality of bus bars, an insulating holder that holds the bus bars to form a predetermined gap between the bus bars, and a resin insulating layer that covers the bus bars. Each of the bus bars has a terminal portion to be connected to a power source, such as a battery, and a tab to be connected to a winding of a stator. The bus bars are disposed correspondingly with phases of the motor. A plurality of holding grooves are formed in the insulating holder. The bus bars, which are pre-bent in a thickness direction to be shaped into a substantially annular shape, are respectively accommodated in the holding grooves. The pre-bending is preferably carried out by a bending machine.

A centralized power distribution unit for a vehicular thin brushless motor includes a plurality of bus bars and a resin insulating layer that covers the bus bars. The bus bars are disposed correspondingly with phases of the motor. Each of the bus bars has a terminal portion to be connected to a battery and one or more tabs to be connected respectively to one or more windings of a stator. Each of the bus bars is shaped into a substantially annular shape by bending a molded material in a thickness direction. The molded material is obtained by stamping out a conductive metal plate into a strip-like shape. Diameters of the annular shapes of the bus bars are set to be different from one another depending on the corresponding phase of the motor. The bus bars are stacked in a radial direction of the centralized power distribution unit, mutually separated by a predetermined gap.
