化の大きな妨げとなる。 In order to improve the rotary compressor's COP (coefficient of performance) and make it smaller and lighter, rotary compressors are known that have a built-in motor in which the stator and rotor's magnetic centers are shifted. This is because, as shown in Figure 1, the stacked thickness h 1 and h 2 of stator a and rotor b are the same, so the upper part of rotor b protrudes slightly upward relative to stator a, or conversely, the lower part of rotor b protrudes slightly downward. Furthermore, the strength of the magnetic field generated by passing current through stator a is much stronger in case B than in case A, but it is unnecessary to have part A of rotor b, that is, a part that protrudes from stator a. At the same time, the iron loss of rotor b also increases, and the weight of rotor b also increases. Therefore, this becomes a major hindrance to improving the efficiency and reducing the size and weight of the compressor.

ない。 That is, as shown in FIGS. 2 and 3,
The strength of the magnetic field generated by passing current through stator a is in the relationship B≫A, and the force that rotates rotor b is proportional to this strength, so part a plays a major role in the rotation of rotor b. Don't do it. Rather, the iron loss of rotor b is large, and the coefficient of performance of the compressor is not good.

圧縮機を提供しようとするものである。 This invention was made in view of the above circumstances, and its purpose is to reduce the laminated thickness of the rotor by less than 9.5 times the laminated thickness of the stator, thereby reducing iron loss and weight of the rotor, and improving the efficiency of the motor. The present invention also aims to provide an electric compressor that can improve the coefficient of performance of the compressor.

ロータｂのイの部分とロの部分の下部（斜線部
分）が短かく形成されている。 The present invention will be described below based on an embodiment shown in the drawings. In FIG. 4, 1 is a motor, and 2 is a compressor section. The motor 1 is composed of a stator 3 and a rotor 4, and the rotor 4 is interlocked with a rotating body 7 housed in a cylinder 6 of the compressor section 2 via a shaft 5. The magnet centers of the stator 3 and rotor 4 are located offset from each other, and the stacking thickness H 1 of the stator 3 and the stacking thickness H 2 of the rotor 4 are H 1
The stacking thickness H 2 of the rotor 4 is set short so that the relationship of >H 2 is satisfied. That is, the lower portions (hatched portions) of the portion A and the portion B of the rotor b in FIG. 2 are formed short.

ことも確認された。 In addition, the stacking thickness H 1 of the stator 3 and the stacking thickness of the rotor 4
The difference in H 2 is less than 9.5%, as is clear from the graph of the relationship between the lamination difference between the stator and rotor and the coefficient of performance in Figure 5.The lamination thickness H 2 of the rotor 4 is made thinner compared to the lamination thickness H 1 of the stator 3. It has been experimentally found that the coefficient of performance is improved by
It has also been confirmed that by shortening the length, the iron loss and weight of the rotor 4 are significantly reduced, and the efficiency of the motor 1 is improved.
