In this compressor B, a stator 15 having an electromagnetic coil 1 wound around an armature core 2 is fixed to the outer peripheral portion of a partition wall 11 made of a non-magnetic material such as metal. Due to the rotating magnetic field formed by the stator 15, a magnet rotor 14 composed of a magnet piece 3 and a yoke 4 provided in the partition wall 11 so as to face the stator 15 rotates, and a crankshaft 9 connected to the magnet rotor 14 rotates.

渦電流が流れることを防止して，モータ部７に大きい制
動力が発生しないようにしている。In the compressor B, since the magnet piece 3 and the stator 15 are separated by the partition wall 11 made of metal or the like,
Eddy current is generated in the partition wall 11 by the rotating magnetic field formed by the stator 15. Therefore, the above conventional compressor B
Then, the stator mounting portion 10 of the partition wall 11 is formed of a laminated structure of thin rings made of a non-magnetic material and an insulating member to prevent a large eddy current from flowing and prevent a large braking force from being generated in the motor portion 7. I have to.

きくなったり回転不能に陥ったりする欠点がある。In the stator mounting portion of the laminated structure in the conventional compressor B, it is necessary to fix the laminated thin rings one by one with an adhesive or a resin so as to withstand the internal pressure during the operation of the compressor. Due to the large number of rings, complete bonding and centering are extremely difficult, and due to pinholes and other bonding errors and defective heat molding, the internal pressure cannot be withstood, causing gas leaks and abnormal vibrations in the motor due to misalignment. It has a drawback that it causes noise and becomes unrotatable.
そのため，各積層リング間の固着力を高めるため積層
リングの外周を軸方向に溶接することも考えられるが，
各リング間の絶縁性が低下し渦電流回路が大きくなるた
め，望ましい解決策とは言えない。Therefore, it is conceivable to weld the outer circumference of the laminated rings in the axial direction in order to increase the adhesion between the laminated rings.
This is not a desirable solution because the insulation between the rings is reduced and the eddy current circuit becomes larger.
従って，本考案が目的とするところは，積層構造をな

を特徴とする圧縮機として構成されている。To achieve the above object, the present invention includes a rotor having a magnet in a closed partition, and a compression unit integrally connected to the rotor, and is provided outside the partition to face the magnet. In the compressor in which the rotor portion and the compression portion are rotationally driven by the rotating magnetic field formed by the stator, and the stator mounting portion of the partition wall is formed of a laminated structure including a non-magnetic material and an insulating member, The compressor is characterized in that a thin metal cylinder is provided inside the stator mounting portion of the laminated structure, and both ends of the metal cylinder are fixed to the partition wall.
金属筒の両端が，隔壁に溶接等により確実に接着され

また，積層されたリングを一つ一つ接着する作業に比べ

一体化が図れるので，作業性が著しく向上する。Since both ends of the metal cylinder are securely bonded to the partition wall by welding or the like, the risk of gas leakage is reduced and reliability is improved.
Further, as compared with the work of adhering the laminated rings one by one, since the whole laminated portion can be integrated only by adhering both ends of the metal cylinder to the partition walls, workability is remarkably improved.
