摘要： PROBLEM TO BE SOLVED: To easily fill the area between wiring members with resin when the bus bar of an electric motor is formed by injection molding.
SOLUTION: The bus bar 51 attached to the armature of an electric motor includes: four wiring plates 516 disposed perpendicularly to the central axis at intervals in the direction in which the central axis is oriented; and a resin portion 517 formed by injection molding so that it completely wraps the four wiring plates 516. A resin passage hole 519 that is a through hole through which resin passes when the resin portion 517 is molded is formed in the wiring plates 516. When the bus bar 51 is molded, resin is injected into a mold for resin molding with the four wiring boards 516 supported by support pins provided in the mold. Resin moves in the space between the mold and the wiring boards 516 and in the spaces between the adjacent wiring boards 516 through the resin passage hole 519 in each wiring board 516 and from space to space. Therefore, the area between the wiring boards 516 can be easily filled with resin.

摘要： PROBLEM TO BE SOLVED: To provide a structure which enables a bus bar holder to be positioned in the axial direction and also enables a claw part and a receiving part to be arranged without causing unnecessary stress in the bus bar holder or an insulator even when an axial dimension error occurs in the bus bar holder or the insulator in a motor having a bus bar.SOLUTION: A bus bar holder 232A holding a bus bar 231A has an annular holder body part 60A and a first leg part 61A and a second leg part 62A which extend downward from the holder body part. The first leg part 61A has a claw part 611A protruding in the lateral direction. An upper surface of the claw part 611A faces a lower surface of a receiving part 521A provided at an insulator in the axial direction through a gap. Thus, the bus holder 232A is restricted from moving upward by the claw part 611A and the receiving part 521A of the insulator. On the other hand, a lower end part of the second leg part 62A is in contact with a teeth 512A or the insulator 52A.

摘要： PROBLEM TO BE SOLVED: To provide a motor that suppresses deflection of a magnetic member to focus the direction of sensor magnet flux on a magnetic sensor, thereby improving the detection accuracy of the magnetic sensor.SOLUTION: A motor static part 2A includes a housing 21A, an armature 22A, substrate 61, a magnetic sensor 62A, and a plate-like magnetic member 63A. The substrate 61A and the magnetic member 63A are fixed by fastening at a plurality of fixing positions in the axis direction. A motor 1A is provided with a rib 81A on the upper surface of the magnetic member 63A. The rib 81A extends in such a manner as to connect the proximity of one of the plurality of fixing positions with the proximity of another of the plurality of fixing positions. This suppresses deflection of the magnetic member 63A that is attributed to fastening in the axis direction. Thus, the direction of flux of the sensor magnet 35A is focused on the magnetic sensor 62A. Accordingly, the detection accuracy of the magnetic sensor 62A is improved.

摘要： PROBLEM TO BE SOLVED: To insulate coils and a core from each other in an inner rotor motor without fail. SOLUTION: The armature 3 of an inner rotor motor includes multiple teeth 31, a support ring 33 that supports the multiple teeth 31 from outside, insulators that cover the multiple teeth 31, and coils 35 formed by winding conductors from outside the teeth 31. The insulators consist of teeth insulators 321 constructed of substantially annular upper member and lower member installed from above and beneath the teeth 31, an outside insulator, an upper insulator 323, and a lower insulator. In the armature 3, contact between the outside surfaces of the coils 35 and the inner circumferential surface of the support ring 33 is prevented by the outside insulator, and contact between the coils 35 and the side faces of the teeth is prevented by the teeth insulators 321. As a result, the coils 35 and the core 30 can be electrically insulated from each other with ease and reliability. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a motor in which a bus bar unit is widened in a radial direction to reduce the lamination number in an axial direction of a bus bar, and suppress the dimension in the radial direction of the entire motor.SOLUTION: A metal bus bar 51A includes a tabular part 511A and a plurality of terminals 512A. The tabular part 511A expands along a plane substantially orthogonal to the center axis. A bus bar unit 24A consisting of the bus bar 51A and a bus bar holder 52A and a rotor 32A are overlapped each other in the axial direction. Therefore, the bus bar unit 24A can be widened in the radial direction and the dimension in the radial direction of the entire motor 1A can be suppressed in comparison with a case in which the bus bar unit 24A and the rotor 32A are not overlapped each other in the axial direction. If the bus bar unit 24A is widened in the radial direction, the lamination number in the axial direction of the bus bar 51A can be reduced. Consequently, the dimension in the axial direction of the motor 1A can be suppressed.
