摘要： In a conventional compressor, since a motor and a mechanical section of the compressor are disposed in one and the same closed container, the motor is exposed to high-temperature coolant and heated, and the efficiency of the motor is lowered. Further, during the operation of the compressor, the coolant circulating in the refrigerating cycle conveys additional heat generated by the motor coil. Thus the efficiency of the refrigerating cycle is lowered. The compressor according to the present invention includes a compression chamber divided into a closed chamber and an open chamber separated by a magnetic induction plate from each other. The closed chamber is filled with high temperature and pressure coolant and the rotor of the motor is disposed in the closed chamber, and the stator of the motor is disposed in the open chamber.

摘要： A self-starting type axial gap synchronous motor includes a stator in which plural small stators are arranged on the same circumference; disc-shaped rotors in each of which plural permanent magnets facing the stator are arranged on the same circumference; and a shaft coupled to the rotors. Each of the disc-shaped rotors includes a metal frame that is provided so as to surround the plural permanent magnets arranged on the same circumference, and each of the metal frames is configured using a nonmagnetic and conductive material.Accordingly, it is possible to obtain a self-starting type axial gap synchronous motor that can be started by a commercial electric power without using an inverter, and a compressor and a refrigeration cycle apparatus using the same.

摘要： There is provided a self-starting permanent magnet synchronous motor in which a center axis of magnetic poles of a rotor is assumed to be a d axis, an axis deviated from the magnetic pole center axis by an electric angle of 90 degrees is assumed to be a q axis, at least two or more starting bars which are arranged near the d axis are arranged on a bore side of the bars near the q axis and are arranged in parallel with the q axis, so that a stable starting torque can be generated irrespective of a generating position of a stator magnetic flux which changes due to applying timing of a power source and a phase of a voltage, and a vibration/noises at the time of a stationary operation can be reduced.
