Claims

[Claims for Utility Model Registration] (1) A low melting temperature light alloy is melted and interposed between a plurality of arc-shaped permanent magnets constituting an annular permanent magnet and a magnetic yoke disposed inside the arc-shaped permanent magnets. A rotor for a rotating electric machine, characterized in that the two are integrally molded and fixed by solidifying the rotor. (2) Claims for registration of a utility model, characterized in that the arc-shaped permanent magnet has a notch at each end on both sides of its outer periphery, and the low melting temperature light alloy is melted and inserted into this part. The rotor of the rotating electric machine according to item 1. (3) The above-mentioned arc-shaped permanent magnet has small-diameter stepped portions on both sides of its outer periphery, and the low-melting-temperature light alloy is melt-inserted into these portions, the scope of the utility model registration claim No. The same trochanter for the rotating electric machine according to item 1. (4) Claims 1, 2, or 3 of the utility model registration claim characterized in that both end surfaces and the entire inner peripheral surface of the magnetic yoke are covered with the low melting temperature light alloy. rotor of rotating electric machine.
