Abstract

The invention relates to an electric compressor (7) comprising: a compression mechanism (3); an electric motor (2) for 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) is mounted in an inverter housing (10), while the electric motor (2) is mounted in a 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). According to the invention, the motor (2) comprises a stator (2A) of circular periphery. Moreover, the internal periphery of the motor housing (20) is provided with a plurality of protuberances (23) that are in contact with the circular periphery of the stator (2A), and the internal periphery of the motor housing (20) is provided with a plurality of openings (29), between two consecutive protuberances (23), with at least one securing device (5) extending through the openings.

Description

technical field

[0001] The technical field of the invention is that of electric compressors, which are equipped by electric vehicles, for example, to circulate refrigerant in the vehicle's air conditioning circuit or in a heat pump. Background technique

[0002] Electric compressors generally include a compression mechanism driven by an electric motor in order to circulate refrigerant in an air conditioning circuit. To power the electric motor and vary its speed, the compressor also includes an inverter. As an example, an inverter is designed to convert single-phase current into three-phase current.

[0003] Such compressors are known in the literature. Document JP2003-343438A describes an electric compressor (not shown), which includes a compression housing in which a compression mechanism is installed, a motor housing in which an electric motor is installed, and an inverter housing in which an inverter is installed . In order to join the housings together, the outer su...
