Abstract
A rotor includes: a plurality of first magnetic pole members that are disposed such that first end portions and second end portions are respectively coupled magnetically and mechanically to a first magnetic end plate and to a second magnetic end plate and so as to be separated from a magnetic intermediate plate magnetically; a plurality of second magnetic pole members that are disposed such that intermediate portions are coupled magnetically and mechanically to the magnetic intermediate plate and so as to be separated from each of the magnetic end plates magnetically; a plurality of permanent magnets that are disposed between the first and second magnetic pole members in a circumferential direction; and a nonmagnetic holding body for separating the first magnetic pole members magnetically from the magnetic intermediate plate, and for separating the second magnetic pole members magnetically from the magnetic end plates.
