PROBLEM TO BE SOLVED: To enable a plurality of magnets to be adhered on the inside circumferential source of a yoke, in such a way as to face the magnetic poles of a stator core with the magnets held at specified positions accurately by using magnet holders, and to enable the magnet holders to be mounted so that there will not to drop inside the yoke or turning. SOLUTION: This rotor for a dynamo-electric machine comprises a plurality of magnets, held at equal intervals, by magnet holders partitioned by ribs and adhered to the inside circumferential surface of the yoke, in such a way as to face the magnetic poles of the stator core. When each holder element of the magnet holders split into halves in the axial direction is fitted to each other, the rib portion in one holder element and the rib portion in the other holder element that face each other are configured, to fit by recessed and protruding structures. On the side of the ring-shaped portion in each holder element is provided a hook-shaped protrusion having spring characteristics. The protrusions are fitted into the recessed grooves, provided on the inside circumferential surface of the yoke. A protruding portion is provided at the bottom surface of the ring-shaped portion of the holder element and fitted into a hole formed in the base portion of the yoke. COPYRIGHT: (C)2006,JPO&NCIPI
