PROBLEM TO BE SOLVED: To facilitate adjustment of rotor axis, in a dynamo-electric machine where a stator and a rotor are encased.SOLUTION: A fixing ring 54 for fixing a resolver rotor 52 to a rotor shaft 20 has a square outer peripheral shape. A hole 60 is bored in the side face of a case 16 for housing a stator 14 and a rotor 12. An adjusting rod 62 is inserted into the case 16 from the hole 60, and the tip of the adjusting rod 62 abuts against an abutment plane 58 corresponding to each side of square outer peripheral side face of the fixing ring 54. The axial position of the rotor shaft 20 is adjusted by advancing and retracting four adjusting rods 62 abutting, respectively, against four abutment planes 58, and a case cover 36 is fixed to the case body 34 at a predetermined position. |
