Embodiment Construction

[0042]The invention relates to a motor comprising a rotor, a stator, a housing and a stator cooling device. The rotor and stator are used to generate electrical current (the "generator" mode of the electric motor) or to have the rotor rotated by the current (the "motor" mode of the electric motor). The purpose of the enclosure, also simply referred to as the housing, is to protect the internal equipment of the motor (including the rotor and stator) from external aggression (eg, splashing water), and to protect the user from electrical hazards and the so-called "rotating motors" associated with the motor risk. The rotor and stator are coaxial along a longitudinal axis, allowing the rotor to rotate within the stator. The stator includes flux generators, such as coils. When the motor is running in "motor" mode, the flux generator produces the flux that drives the rotor, which is equipped with magnetic receivers such as permanent magnets, into rotation. When the motor is operat...

Abstract

The invention relates to an electric machine comprising a rotor (3), a stator, an outer shell (6) and a means for cooling the stator. The rotor (3) and the stator are coaxial about a longitudinal axis(xx) and the stator comprises magnetic flux generators (5). The means for cooling the stator comprise at least two means for circulating a fluid, at least one first circulation means extending longitudinally inside the stator to form a first flux formed by F1A and F1B and at least one second circulation means being positioned on the perimeter of the stator to form a second flux F2. The inventionlikewise relates to a compressor and a turbine compressor electrified with such an electric machine.

Description

technical field [0001] The present invention relates to an electric machine for use in an electric machine, in particular an electric machine that can be used in an electrically assisted compression device for compressing a working fluid, such as a liquid fluid or a gaseous fluid. [0002] The invention relates in particular to a device for compressing a gaseous fluid, in this case air, by means of a compressor, separate or associated with a turbine so as to form a turbocharger, before delivering it to any device, And more particularly the delivery of a gaseous fluid to the intake of an internal combustion engine. [0003] The invention may particularly prove to be relevant in the field of transport (for example engines or heavy-duty transport), the field of aerospace, the field of power generation or the food industry, the petroleum industry, the field of construction or the field of medical / paramedicine. [0004] In fact, as is widely known, the power delivered by an intern...
