ROTARY ELECTRIC MACHINE WITH REDUCED INERTIA

摘要

The invention mainly concerns a rotary electric machine, in particular intended for an electric compressor (1) for a motor vehicle, said machine comprising: - a rotor (10) mounted to rotate about an axis of rotation, - a stator (9) surrounding said rotor (10) with the presence of an air gap (11), characterised in that a ratio between an outer diameter of said stator (9) and an axial length of said rotor (10) is of between 3 and 4.
