摘要： A rotor piece has a plurality of holes 12. Each hole holds therein a plurality of substantially divided permanent magnets 14 that are arranged in a circumferential direction. Therefore, each permanent magnet is small and the flow passage of eddy currents becomes narrow, so that the magnitude of eddy currents becomes small. The total eddy currents in all the permanent magnets is also reduced, so that the eddy current loss can be reduced and the heat generation of the motor can be reduced. Adjacent ones of the substantially divided permanent magnets may be interconnected at portions thereof. One or more of the substantially divided permanent magnets 14 in one or more holes may be ferrite magnets, with other permanent magnets being rare-earth magnets.

摘要： A stator core for a motor in which a member with rounded edges is used to prevent the electrical breakdown of the winding of a coil which may occur at a slot edge therein. End plates 18 are disposed on ends of the stator core 10 formed of laminated magnetic steel plates 12. Each of the end plates 18 has substantially the same pattern as each magnetic steel plate 1, viewed from the axis of the motor. The elongate surface 18a of the end plate 18 continues smoothly from the inner surface 16a of each of slots 16 to the rounded edge surface 18b. The rounded edge surface extends smoothly from the elongate surface 18a to the end surface 18c of the end plate 18. This structure can eliminate sharp edges from the fringe of the slot 16, thus preventing the electrical breakdown of a coated conductor 22 in the coil which may occur at the edges.

摘要： A power output apparatus 20 implements a smooth switching between the connection of a rotor-rotating shaft 38 of an assist motor 40 with a crankshaft 56 of an engine 50 and the connection of the rotor-rotating shaft 38 of the assist motor 40 with a drive shaft 22, and enables the power output from the engine 50 to be output to the drive shaft 22 with a high efficiency. The power output from the engine 50 is converted to a desired power by a clutch motor 30 having rotors 31 and 33 respectively linked with the crankshaft 56 and the drive shaft 22 and by the assist motor 40 connected to either the crankshaft 56 or the drive shaft 22 via a first clutch 45 and a second clutch 46, and is output to the drive shaft 22. The connection of the assist motor 40 is switched in the state where both the clutches 45 and 46 are set in ON position, when the revolving speed of the engine 50 is made coincident with the revolving speed of the drive shaft 22. This effectively reduces a variation in torque output to the drive shaft 22 in the course of the switching operation and enables the power to be output to the drive shaft 22 even in the course of the switching operation.

摘要： Directional electromagnetic steel plates are laminated, and a plurality of stator and rotor core segments are produced by generating into an approximate U-shape so as to provide a U-shaped cross section of the lamination. The direction of high magnetic permeability of the directional electromagnetic steel plates is aligned during lamination with the direction along said U-shape. The side portions of the U-shape adjoin each other and are arranged along the circumference to produce the stator and rotor cores. As the electromagnetic steel plates are laminated, fluctuation in the components in the circumferential direction of the magnetic flux within the magnetic poles and salient poles can be reduced, and iron loss can thus be lowered. In addition, the direction of high magnetic permeability of the directional electromagnetic steel plates coincides with the direction of the magnetic flux creating a much stronger magnetic flux.
