A compressor for a system for air-conditioning the passenger compartment of a motor vehicle comprises a casing enclosing a system for compressing a refrigerant fluid, an electric motor for driving the compression system and electronic means for control of the electric motor. A low-pressure intake chamber (24) for the refrigerant fluid is integrated into the casing (6) and is separated from the high-pressure chamber by a separating partition (26). The electronic means for control of the electric motor (12), which are placed in the intake chamber (24), are cooled by the refrigerant fluid. A separate chamber (34) for connection of the motor (12), defined in the casing (6), communicates with the high-pressure chamber (15) via a passage (36). The chambers (24) and (34) are closed off by a cover plate (20) equipped with all the connecting terminals of the compressor.
