Abstract

An electrical machine () coupled to a compressor () having a rotatable shaft (), comprising: a rotor forming part of the rotatable shaft and having at least two magnetic portions (A,B) separated by an inclined non-magnetic portion () and two elements (A,B) of non-magnetic material at each end of the rotatable shaft, a stator comprising a laminated magnetic iron stack () surrounded by a winding () and disposed along a periphery of the rotor to define a first annular gap (), a ring () of non-magnetic material disposed around the stator, and a casing () of magnetic material comprising permanent magnets (), disposed around the non magnetic ring and having radial walls (A,B) that project inwardly towards the rotor by defining a second annular gap () therebetween.
