摘要： A core comprises a plurality of core split members having yoke portions and tooth portions and arranged in such a circumferential shape that the yoke portions contact with each other while the tooth portions being directed inward. The core further comprises a ring contacting with the yoke portions, and stoppers mounted on the outer face sides of the yoke portions for fixing the ring on the yoke portions. The yoke portions and the ring are formed in corrugated shape to mesh with each other, and the stoppers are formed with projections that engage with the inner side of the ring. This structure provides both the rotating electrical machine core having the core split members arranged in the circumferential shape and fastened to each other while preventing occurrence of a stress and a positional displacement between the core split members, and a rotating electrical machine.

摘要： A stator core is composed of two compacts of compressed powder magnetic cores joined in the axial direction. A yoke portion includes projections projecting axially outward from end surfaces in the axial direction of a tooth. The length in the axial direction of the tooth is gradually reduced radially toward the outside of the stator core, and the length in the circumferential direction of the tooth is gradually increased radially toward the outside of the stator core. A molding is formed by pressing magnetic powder placed in a die by a single punch placed on one side in the axial direction and two punches placed parallel to each other on the other side in the axial direction. The stator core for a rotary electric machine is thus produced.

摘要： In a stator core composed of a powder compacted magnetic body, a yoke part comprises a protrusion protruding from an axial end face of a tooth. The tooth has an axial length gradually decreases towards an outside along the radial direction of the stator core, and a circumferential length which gradually increases towards an outside along the radial direction of the stator core. In one of the cross sections of stator core perpendicular to a radial direction, the height difference between axial end faces of the yoke part and the tooth is substantially equal to an axial length of a coil end part. Further, a cross-sectional area of the tooth perpendicular to the radial direction is substantially maintained constant along the radial direction, and the cross-sectional area is secured at a junction between the tooth and the yoke part, while half of the cross-sectional area is secured in a circumferential cross section of the yoke part.

摘要： A stator core includes a pressurized powder core section which is produced by compression-molding a magnetic powder covered by an insulation coating. At least a portion of the pressurized powder core section forms at least a part of a winding slot section around which a winding is wrapped. The pressurized powder core section comprises a winding guide groove which prevents the winding from deviating along the extending direction of the winding slot section. As a result, a space factor of the winding can be increased, to thereby further improve motor output.

摘要： A vehicle drive device includes a motor generator (MG2), a power control unit controlling the motor generator (MG2), and a case housing the motor generator (MG2) and the power control unit. The power control unit includes a first inverter driving the motor generator (MG2) and a voltage converter boosting a power supply voltage to apply the voltage to the first inverter. A reactor L1 which is a component of the voltage converter is disposed such that at least a portion of a core comes into contact with the case for heat exchange. Consequently, the heat is dissipated to the case having a large heat capacity for integral housing, to thereby allow the heat dissipation performance of the reactor (L1) arranged in the limited space to be ensured.
