    摘要: Firstly, a flat conductor raw wire is formed in a rectangular cross-section and bent in a continuous meandering pattern in a same plane to include in-slot wire portions arranged in each slot of the stator core, coil-end wire portions arranged as a coil end outside the slots, and bent portions joining the in-slot wire portions and the coil-end wire portions. Thereafter, in a setting step, the bent portions located at the opposite ends of the in-slot wire portion are grasped by a pair of grasping tools and the in-slot wire portion is grasped by a twisting jig. Next, in a processing step, the bent portions are twisted and bent into crank-shape by displacing a predetermined axis to a predetermined direction while rotating the twisting jig about the axis. The flat conductor is obtained by performing the setting step and the processing step each of the in-slot wire portions.

    摘要: A motor includes a shaft component, an upper plate portion, a lower plate portion, and a sleeve portion. The shaft component includes an inner shaft portion and an outer shaft portion. The upper plate portion defines a single monolithic member with one of the inner shaft portion and the outer shaft portion. The lower plate portion defines a single monolithic member with the other of the inner shaft portion and the outer shaft portion. The sleeve portion is disposed between the upper plate portion and the lower plate portion. A radial gap is defined between the sleeve portion and the outer shaft portion. A fixing range in which the outer shaft portion and the inner shaft portion radially overlap is arranged. At least a portion in an axial direction of the fixing range radially overlaps with an existing range in the axial direction of the radial gap.

    摘要: A rotary unit of a motor includes a tubular hub portion. A bearing mechanism of the motor includes a bearing portion positioned radially inward of the hub portion. A stationary unit of the motor includes a stator fixing portion positioned inward of the hub portion and higher than a lower end of the hub portion. A cylinder gap is defined between the hub portion and an upper section of the bearing portion. A first communication gap is defined between a lower section of the hub portion and an upper section of the stator fixing portion. A second communication gap is defined between the lower end of the hub portion and a radial inner section of the stator core.
