ABSTRACT:
A rotary shaft60having an outside diameter larger than the bore diameter of a rotary shaft insert hole59of a rotor50is inserted into the rotary shaft insert hole59. A magnet insert hole51a1is provided in a main magnetic pole [a] of the rotor50. Permanent magnets52a1to52a3are inserted into the magnet insert hole51a1such that a gap is formed between the permanent magnets52a1to52a3and the magnet insert hole51a1. A semi-tubular rivet insert hole55aand interlocks57a1, 57a2elongated in the radial direction of the rotor are disposed radially outward of the magnet insert hole51ain the rotor. A semi-tubular rivet56ais inserted into the semi-tubular rivet insert hole55asuch that a gap is formed between the semi-tubular rivet56aand the semi-tubular rivet insert hole55a. Passage holes58ab,58da are provided in the auxiliary magnetic poles [ab], [da].
