Patent ID: 7021075

Claim:
An electric-powered compressor comprised of a compression mechanism for sucking in and compressing a refrigerant and an electric motor for driving said compression mechanism formed integrally and provided at a refrigerant suction side of said compression mechanism with a motor drive circuit for driving said motor, wherein said refrigerant suction side is a housing for storing said compression mechanism and said motor and circulates inside it the suction refrigerant sucked in by said compression mechanism, at least part of a control circuit provided at said motor drive circuit and controlling the operation of a switching device for adjusting the power supplied to said motor is provided abutting against the surface of said refrigerant suction side or a heat conduction member extending from said surface, and said control circuit is provided on a circuit board that is supported by a support member, and the heat conduction member extends integrally from an outer wall of the housing toward the circuit board and abuts against an electronic circuit device of the control circuit.
