Document Type and Number:
Japanese Patent JP4815204
Kind Code:
B2
Abstract:
A rotary shaft 60 having an outside diameter larger than the bore diameter of a rotary shaft insert hole 59 of a rotor 50 is inserted into the rotary shaft insert hole 59. A magnet insert hole 51a1 is provided in a main magnetic pole [a] of the rotor 50. Permanent magnets 52a1 to 52a3 are inserted into the magnet insert hole 51a1 such that a gap is formed between the permanent magnets 52a1 to 52a3 and the magnet insert hole 51a1. A semi-tubular rivet insert hole 55a and interlocks 57a1, 57a2 elongated in the radial direction of the rotor are disposed radially outward of the magnet insert hole 51a in the rotor. A semi-tubular rivet 56a is inserted into the semi-tubular rivet insert hole 55a such that a gap is formed between the semi-tubular rivet 56a and the semi-tubular rivet insert hole 55a. Passage holes 58ab, 58da are provided in the auxiliary magnetic poles [ab], [da].
