ROTATOR OF ROTATING ELECTRICAL MACHINE

PROBLEM TO BE SOLVED: To stably fix a permanent magnet while decreasing leakage of a magnetic flux in the present invention.SOLUTION: A first-layer intermediate member 10 is inserted into a magnetic pole center position of a first-layer magnet insertion hole 12. A second-layer intermediate member 11 is inserted into a magnetic pole center position of a second-layer magnet insertion hole 13. Fitting grooves 18 are provided in the outside-diameter side edge portion of the first-layer intermediate member 10 and the second-layer intermediate member 11, and in the inside-diameter side edge portion of the first-layer intermediate member 10 and the second-layer intermediate member 11. Fitting projections 19 fitted in the corresponding fitting grooves 18 are provided in a first-layer outside-diameter side inner-circumference surface 12a, a first-layer inside-diameter side inner-circumference surface 12b, a second-layer outside-diameter side inner-circumference surface 13a and a second-layer inside-diameter side inner-circumference surface 13b.SELECTED DRAWING: Figure 5 【課題】本発明は、磁束の漏れを低減しつつ、永久磁石を安定して固定することを目的とするものである。【解決手段】１層目中間部材１０は、１層目磁石挿入孔１２の磁極中心位置に挿入されている。２層目中間部材１１は、２層目磁石挿入孔１３の磁極中心位置に挿入されている。１層目中間部材１０及び２層目中間部材１１の外径側端部と、１層目中間部材１０及び２層目中間部材１１の内径側端部とには、それぞれ嵌合溝１８が設けられている。１層目外径側内周面１２ａ、１層目内径側内周面１２ｂ、２層目外径側内周面１３ａ、及び２層目内径側内周面１３ｂには、対応する嵌合溝１８に嵌め合わされた嵌合突起１９がそれぞれ設けられている。【選択図】図５
