PURPOSE:To effectively function the clamping torque of a bolt by clamping the seat surface of a clamping bolt passing hole formed at a stator laminated with silicon steel plates to a supporting frame by pressing in advance, thereby eliminating the gap between the laminated layers of the stator. CONSTITUTION:A motor unit 3 having a stator 6 and a rotor 7 and a compressor body mounted with a supporting frame 4 with a compressor section 2 are elastically suspended by a hanging spring 5 in an enclosed container 1. The stator 6 is formed by laminating silicon steel plates, the seat surface 11 around a bolt passing hole 13 for mounting on the frame 4 is pressed in advance, and clamped fixedly to the frame 4 with a bolt 10. In this manner, the laminates of the stator 12 is contacted closely to each other, and the seat surface 11 of the hole 13 is hardened by processing, and the intrusion of the bolt 10 into the stator 12 can be prevented. |
