However, since an air conditioner or an electric refrigerator requires a large operating torque at the time of starting, a motor having a large operating torque which is larger than a steady operating torque required at the time of normal operation is mounted. I was If the operating torque of such an induction synchronous motor at the time of starting is increased, the power consumption during normal operation is also increased. For this reason, considering high efficiency due to recent energy regulations, etc., the operating torque at start-up of the electric motor used for the hermetic electric compressor constituting a refrigeration cycle such as a refrigerator or an air conditioner is not necessarily sufficient. Did not. Therefore, power consumption during normal operation is small,
Needless to say, there has been a demand for the development of a drive device for an induction synchronous motor that can ensure the operating torque at the time of starting.

When the power switch 49 is closed, a current flows from the single-phase AC commercial power supply AC to the main winding 7A and the auxiliary winding 7B. When a large current flows through the auxiliary winding 7B when the induction synchronous motor 2 starts, almost no current flows through the relay coil 45A. Therefore, the starting relay contact 45B of the starting relay 45 remains closed, and the auxiliary winding 7B is connected in parallel. Starting induction torque is obtained from the current phase difference between the operating capacitor 47, the starting capacitor 48, and the main winding 7A, and the induction synchronous motor 2 starts operating. Then, in the process of the induction synchronous motor 2 shifting to the steady operation, the current flowing through the auxiliary winding 7B decreases, whereby the current flows through the relay coil 45A, and the magnetomotive force of the relay coil 45A opens the power switch 49 to start. The capacitor 48 is disconnected, and the induction synchronous motor 2 continues the steady operation by the current phase difference between the main winding 7A and the auxiliary winding 7B by the operation capacitor 47.
Note that current control using a thyristor may be performed instead of the starting relay 45.

The driving device T2, which switches between the starting capacitor 48 and the operating capacitor 47 by the starting relay 45, has a high starting operating torque and a high rotation speed n of the induction synchronous motor 2, and is operated in the process of shifting to a steady operation. Since a current flows through the coil 45A and the starting relay contact 45B is opened to disconnect the starting capacitor 48, the same operation as the rotating torque T with respect to the rotational speed n of the driving device T3 is performed thereafter. This makes it possible to increase the operating torque at the time of starting the induction synchronous motor 2 and reduce the power consumption during the normal operation, so that the induction synchronous motor 2 can be operated with extremely high efficiency.

Then, when the compressor 3 of the hermetic electric compressor C is driven, the refrigerant sealed in the refrigerant circuit is sucked from the suction pipe 23 to the first rotary cylinder 9 and the second rotary cylinder 10. Then, it is compressed in two stages and discharged from the discharge pipe 22 to the pipe 27. The compressed gas refrigerant discharged into the pipe 27 flows into the condenser 28, where it radiates heat and is condensed to become a liquid refrigerant and flows into the receiver 29. Part of the liquid refrigerant that has flowed out of the liquid receiver 29 also flows into the liquid injection circuit 58, is throttled by the capillary tube 54 via the strainer 52 and the electromagnetic valve 53, and is then discharged into the compressor 3.
