An air-conditioner, an outdoor unit and an refrigeration device each using a refrigeration cycle which can reduce power consumption so as to be highly efficient, which can be operated by a commercially available power source, and which is highly reliable. An air-conditioner comprises a motor and a refrigeration cycle including a compressor driven by the motor, an outdoor heat-exchanger and an indoor heat-exchanger, the motor being located in a motor chamber within a closed container, and refrigerant gas in the refrigeration cycle flows through the motor chamber, wherein the motor has a core of a rotor in which a cage type conductor and permanent magnets magnetized in bipolar state are embedded, and said motor is driven by a commercially available electric power source.

[ We claim:] [1.]1. An air-conditioner comprising a motor and a refrigeration cycle including a compressor driven by said motor, an outdoor heat-exchanger and an indoor heat-exchanger, said motor being located in a motor chamber within a closed container, and refrigerant gas in the refrigeration cycle flows through the motor chamber, wherein said motor has a core of a rotor in which a cage type conductor and permanent magnets magnetized in bipolar state are embedded so as to serve as a synchronous motor, and said motor is driven by a commercially available electric power source.
