摘要： A rotor includes a tubular sleeve member, a plurality of permanent magnets aligned in a peripheral direction on an outer peripheral surface of the sleeve member, and a tubular reinforcing member covering an outer peripheral surface of the permanent magnets. The sleeve member includes first and second end portions, which are spaced apart from each other in an axial direction, and an inner peripheral surface forming a through hole that is parallel to the axial direction and through which a shaft passes. The first end portion is a flange portion. The inner peripheral surface includes a first tapered surface, an inner diameter of which is continuously reduced toward the second end portion from the first end portion, and a tapered surface, an inner diameter of which is continuously reduced toward the end portion from the second end portion.

摘要： A rotor for an induction motor 300 including end rings having an annular shape, which is provided at an end of a rotor core and is connected to a conductor bar projecting from the end of the rotor core, and first reinforcing members having an annular shape, each of which is provided between the rotor core and the corresponding one of the end rings and is in contact with the corresponding one of the end rings. The first reinforcing members each have an insertion hole formed therein to which the conductor bar projecting from the end of the rotor core is to be inserted.

摘要： In a rotary electric machine, a conductive member surrounds a shaft and a plurality of permanent magnets provided on an outer peripheral portion of the shaft as a whole, and a holding member surrounds the shaft, the plurality of permanent magnets, and the conductive member as a whole. A conductivity of the conductive member is higher than a conductivity of the permanent magnet. The conductive member includes first and second opposing portions that oppose each other via a gap in a circumferential direction. An inter-opposing portion region existing between the first and second opposing portions is positioned within a circumferential direction range of an inter-magnet region existing between permanent magnets that are adjacent to each other in the circumferential direction.

摘要： This squirrel-cage motor rotor includes a plurality of conductor bars provided at regular intervals along the circumferential direction of a rotor core, short-circuit rings connected to ends of the conductor bars, and reinforcement covers having axial-direction surfaces being in contact with axial-direction-end surfaces of the short-circuit rings. The reinforcement covers are enclosed by casting in the short-circuit rings. Holding rings are attached to the outer circumferential surfaces of the flange portions of the reinforcement covers and the outer circumferential surfaces of the short-circuit rings by interference fit.
