ABSTRACT:
A magnetic member with an annular outer periphery and an inner periphery includes first portions and second portions alternately disposed in its circumferential direction. The first portions and second portions are magnetically separated in the circumferential direction by gaps, which block magnetic fluxes from flowing in the circumferential direction between the first portion and second portion. The first portions respectively have holes extending almost in the circumferential direction. The gaps are provided at both ends of the holes in the circumferential direction between the outer periphery and inner periphery. An interior permanent magnet type rotor can be structured by inserting field magnets into the holes.
