Abstract
The present invention provides a rotating electrical machine capable of fixing a permanent magnet at a defined position of a magnet insertion hole without providing a filling groove for injection of a filler in a rotor core and, of course, without lowering performance as the rotating electric machine. A rotating electrical machine of the present invention includes: a rotor; and a stator, the rotor including: a rotor core provided with a plurality of magnet insertion holes; a permanent magnet inserted into the magnet insertion hole; and a filler configured to fix the permanent magnet to the magnet insertion hole. In the rotating electrical machine, the permanent magnet comprises: a plurality of radial end surfaces provided in a radial direction of the rotor; and a pair of circumferential end surfaces provided in a circumferential direction of the rotor, one first radial end surface out of the plurality of radial end surfaces intersects the pair of circumferential end surfaces to form two regions where a side meets a side, and gaps each of which is formed between each of the two regions where a side meets a side and an inner wall surface of the magnet insertion hole are used as filler inlets for the filler.
