Abstract
Provided is a rotor for a rotating electrical machine which is capable of minimizing increases in eddy current losses via a magnet, while making insulating film processing of the surface of the magnet unnecessary. The rotor for the rotating electrical machine includes: a rotor core having a magnet insertion hole extending inside; a magnet inserted in the magnet insertion hole; and an insulating filler which is filled between the inner wall of the magnet insertion hole and the magnet so as to secure the magnet. The magnet is secured by the filler in such a manner that the surface of the magnet inside the magnet insertion hole is in an inclined position with respect to the extending direction of the inner wall of the magnet insertion hole.
