Abstract: A rotor is configured such that the rotor includes: a rotary tube whose inner circumferential surface is tapered and which is fitted to a rotary shaft whose outer circumferential surface is tapered; a permanent magnet which is arranged on the outer circumferential side of the rotary tube; and a sheath tube which is fitted to the outer circumferential side of the permanent magnet so as to cover the permanent magnet, and that as the outside diameter of a multilayer member formed with the rotary tube and the permanent magnet is reduced so as to be tapered along an axial direction, the interference of the sheath tube for the multilayer member is increased so as to be tapered along the axial direction.

Abstract: A rotor including a cylindrical iron core having a through hole for receiving a rotational shaft, and a squirrel-cage conductive body including a plurality of conductive bars and a pair of annular conductive end rings provided at both ends of the plurality of conductive bars is provided. The conductive bars extend along a direction in which the rotational shaft is received and are arranged at an outer circumference of the iron core at certain intervals. The rotor further includes a conductive reinforcing layer extends on at least a part of an outer surface of the conductive end ring. The conductive reinforcing layer is formed by spraying conductive particles in a solid phase onto the outer surface of the conductive end ring.

Abstract: A rotor includes a rotary member, a plurality of permanent magnets disposed on an outer circumference of the rotary member, and a cover tube that is mounted to outer circumference of the permanent magnets to cover the permanent magnets, and is formed of a fiber reinforced plastic. At least one of the rotary member and the permanent magnets has a diameter enlarged portion having a diameter enlarged circumferential surface. The diameter enlarged portion has a diameter that enlarges from a first diameter region to a second diameter region. The first diameter region has a diameter equal to or less than an inner diameter of the cover tube. The second diameter region has a diameter equal to or more than an outer diameter of the permanent magnets.
