PERMANENT MAGNET ROTATING MACHINE
First Claim
1. A permanent magnet rotating machine, having a stator and a rotor, the rotor having main magnetic poles and auxiliary magnetic poles which alternate in the circumferential direction when viewed in cross section perpendicular to the axial direction of the rotor, each of the main magnetic poles having a magnet insert hole for receiving a permanent magnet, the magnet insert hole extending in the axial direction of the rotor, the rotor having a rotary shaft insert hole for receiving a rotary shaft and a semi-tubular rivet insert hole for receiving a semi-tubular rivet, the insert holes extending in the axial direction of the rotor, the rotary shaft having an outside diameter larger than a bore diameter of the rotary shaft insert hole, wherein:
- the semi-tubular rivet insert hole is disposed in each of the auxiliary magnetic poles, the permanent magnet is inserted into the magnet insert hole such that a gap is formed between the magnet insert hole and the permanent magnet, and the semi-tubular rivet is inserted into the semi-tubular rivet insert hole that a gap is formed between the semi-tubular rivet insert hole and the assigned semi-tubular rivet.

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].
