Abstract: A rotor includes: a rotating member; a permanent magnet arranged in a plurality of rows along a circumferential direction of the rotating member and divided into a plurality of parts in a rotational axis direction X of the rotating member; and a cover tube divided into a plurality of parts in the rotational axis direction of the rotating member and covering an outer circumferential surface of the permanent magnet, the cover tube being formed of a fiber-reinforced plastic, wherein the plurality of permanent magnets in each row are arranged in an oblique direction with respect to the rotational axis direction of the rotating member, and the permanent magnets adjacent to the arrangement direction are disposed to be skewed in the circumferential direction, and at least one of the divided cover tubes covers an outer circumferential surface of one of the divided permanent magnets in the circumferential direction of the rotating member.

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.
