Rotor of rotating electrical machine

Abstract:

A rotor of a rotating electrical machine includes a substantially annular rotor core with a plurality of magnet insertion holes formed along a circumferential direction and a plurality of magnetic pole portions including permanent magnets inserted into the plurality of magnet insertion holes. The magnet insertion hole includes a first abutment surface on which the outer diameter side first end portion of the permanent magnet slidably abuts and which extends in a substantially linear shape and a second abutment surface on which the outer diameter side second end portion of the permanent magnet slidably abuts and which extends in a substantially linear shape. The inner diameter side first end portion and the inner diameter side second end portion of the permanent magnet are located closer to a center side in the circumferential direction of the permanent magnet than the first imaginary line and the second imaginary line.
