Abstract: An inverter unit (100) includes an inverter (110), an inverter housing (120) and an insulating member (130). The inverter (110) drives an electric motor (200) and includes at least one power module (112) for converting a High Voltage (HV) Direct Current (DC) to a three-phase Alternating Current (AC) that drives the electric motor (200). The inverter housing (120) receives the inverter (110). The power module (112) is mounted on an end wall (120a) of the inverter housing (120) by means of bolts (114). The insulating member (130) corresponding to each bolt (114) is disposed between a head portion (114a) of the corresponding bolt (114) and the power module (112).

Abstract: An electric compressor (7) includes a compression mechanism (3); an electric motor (2) driving the compression mechanism (3), the electric motor having an axis of rotation (X); and an electric motor (2) power supply inverter (1), the inverter (1) being mounted in an inverter housing (10). The compression mechanism (3) is mounted in a compression housing (30), and the electric motor (2) is mounted in a motor housing (20) extending longitudinally along the axis of rotation (X) and having a first end (20P) connected to the inverter housing (10) by a plurality of securing devices (5) extending inside the motor housing (20). The motor housing (20) includes a second end (20S) located opposite the first end (20P) in relation to the electric motor (2) and connected to the compression housing (30) by a plurality of securing devices (6) different from the above-mentioned securing devices (5).

Abstract: The invention concerns an electrical connection device (5) for a compressor, the electrical connection device (5) comprising a connection block (7) for connection to an electric motor (2) of the compressor, a plurality of removable electrical connection elements (72) fitted in a triangle in said connection block (7) to engage with a connection terminal (6) of a control device (1) of said electric motor (2) and at least one electrically insulating element (8) removably mounted on the connection block (7) in such a way as to insulate the electrical connection elements (72) from a wall separating the control device (1) from the electric motor (2), said electrically insulating element (8) being configured to provide a stop for said electrical connection elements (72) when said connection block (7) is inserted into said electrically insulating element (8). The invention also concerns a compressor comprising such an electrical connection device (5).

Abstract: The invention relates to an electric compressor (1) comprising a compression mechanism (3) rotated by a drive device that extends through a main casing (5) defining an internal volume (6) in which an electric motor (2) is installed. The electric motor comprises a stator (10) and a rotor (11) which extends at least partially on the outer periphery of the stator (10), said drive device comprising the rotor (11) solidly connected to a shaft (4) which extends through a plate (7) solidly connected to the main casing (2). The invention is characterised in that it includes a first rotation means (47) between the shaft (4) and the plate (7) and a second rotation means (51) between the drive device and the plate (7). The invention is suitable for motor vehicles.

Abstract: 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.
