Conventional technology In the past, induction motors with squirrel-cage rotors were the mainstream for the motor parts of compressors such as room air compressors, but in recent years, permanent magnet rotors have been used to improve the efficiency of the motor parts. The application of electric motors has been actively studied, and some of them have been put into practical use.

To explain this inner rotor type permanent magnet rotor, as shown in FIG. A plurality of permanent magnets (2) in the form of arc-shaped segments are arranged in the magnet. The inner circumferential surface of the permanent magnet (2) is in contact with the outer circular arc surface of the yoke (3),
Further, the outer peripheral surface of the magnet (2) is formed into an arc shape with a constant outer diameter so as to maintain a predetermined magnetic gap with respect to the inner diameter of the stator (6). The yoke (3) and the permanent magnet (2) are usually fixed using adhesive or the like, but if the rotor rotates at high speeds, there is a risk that the permanent magnet (2) will fly away due to centrifugal force. Generally, a reinforcing member (1) is provided on the outer periphery of the permanent magnet (2). This reinforcing member (1) is made of a non-conductive and non-magnetic resin molding or a fibrous tape wrapping, and maintains a predetermined mechanical gap with respect to the inner diameter of the stator (6). It is formed into a cylindrical shape with a constant outer diameter. Further, when the rotation of the rotor reaches a high speed, the bearing lubricating oil flows out of the compressor together with the refrigerant from the refrigerant discharge pipe (4), so an oil separator (5) for preventing leakage is attached.

発明が解決しようとする問題点 さて上記の如く構成される圧縮機は以下に示す4点の問

Problems to be Solved by the Invention The compressor configured as described above has the following four problems.

(+)  圧縮機の負荷は1回転の中で変化する変動負

(+) The load on the compressor is a variable load that changes within one rotation, and vibration and noise are large during operation.

(1) The motor part is cylindrical, and it is necessary to provide extra space for the coil end (7) that protrudes further in the axial direction from the end face of the stator (6), so the shape of the compressor is vertically elongated. As a result, the compressor storage space becomes larger.

(iii) When the rotor rotates at a high speed, it is necessary to provide a reinforcing member (1) to prevent the permanent magnet (2) from scattering, which increases costs.

OV) Since the rotor is cylindrical, the axial length of the rotor tends to be longer than the outer diameter, and the magnetic and mechanical gap length at the opposite end of the shaft (8) tends to be longer. Since uniformity tends to occur, in order to stabilize this as much as possible, the length of the bearing (9) generally needs to be increased. For this reason, the lubrication of the lubricating oil in the bearing portion deteriorates, making it impossible to reduce the rotational speed below a certain certain level.

Therefore, the present invention solves the conventional drawbacks as mentioned above, and

Means for Solving the Problems In order to achieve the above object, the hermetic electric compressor of the present invention includes an electric motor section having a permanent magnet type rotor in a hermetically sealed casing, and a compressor driven by the electric motor section. The electric motor section is equipped with a stator formed by molding a coil wound with a required number of poles into a flat ring shape and fixing it to the peripheral wall of the casing; A pair of rotating yokes made of magnetic material are arranged opposite to each other with an axial gap on both sides of the child, and at least one of the rotating yokes is attached to face the stator and magnetized to a predetermined number of poles. The compressor section includes a rotor made of a ring-shaped permanent magnet and a shaft to which the rotating yoke is attached, and the compressor section is a rotary compressor having a rotor mechanism attached to the shaft. The rotor mechanism of the compressor section is provided within the inner periphery of the stator.

Function: With this configuration, the flywheel effect of the long magnet and yoke is increased, so vibration and noise during operation are reduced, and the flat shape of the compressor saves space. Furthermore, since the electric motor section is made flat, the bearing section is shortened, which makes it possible to lubricate the bearings at low rotation speeds, making it possible to widen the variable range of the compressor's capacity.
