| Zusammenfassung: | A rotor for a permanent magnet motor, includes a magnetic pole portion that includes a magnetic body formed in an annular shape; and a field portion that is disposed adjacent to the magnetic pole portion in an axial direction, that includes a permanent magnet formed in an annular shape and having a multipole structure or a plurality of permanent magnets formed in an annular shape and having a monopole structure and a magnetic body, and that causes a magnetic flux generated by the permanent magnet to flow in the axial direction so as to generate magnetic poles on an outer circumferential surface of the magnetic pole portion. |
