FIELD: machine building.
SUBSTANCE: rotor for a rotating electrical machine includes the following: a rotor core with a hole for magnet insertion passing inside, a magnet inserted in the hole for magnet insertion, and an insulating filler filling the space between the inner wall of the hole for magnet insertion and the magnet in order to fix the magnet. The magnet is fixed by the filler so that the magnet surface inside the hole for magnet insertion is inclined to the direction of passing of the inner wall in the hole for magnet insertion.
EFFECT: minimisation of losses from eddy current through the magnet which makes processing of magnet surface by insulating film unnecessary.
