Abstract

Official abstract text for this publication.

An electrical machine ( 20 ) coupled to a compressor ( 12 ) having a rotatable shaft ( 16 ), comprising: a rotor forming part of the rotatable shaft and having at least two magnetic portions ( 22 A, 22 B) separated by an inclined non-magnetic portion ( 24 ) and two elements ( 26 A, 26 B) of non-magnetic material at each end of the rotatable shaft, a stator comprising a laminated magnetic iron stack ( 28 ) surrounded by a winding ( 30 ) and disposed along a periphery of the rotor to define a first annular gap ( 32 ), a ring ( 34 ) of non-magnetic material disposed around the stator, and a casing ( 40 ) of magnetic material comprising permanent magnets ( 36 ), disposed around the non magnetic ring and having radial walls ( 40 A, 40 B) that project inwardly towards the rotor by defining a second annular gap ( 42 ) therebetween.

First claim

Opening claim text (preview).

The invention claimed is: 1. An electrical machine coupled to a compressor having a rotatable shaft, comprising: a rotor forming part of the rotatable shaft and having a longitudinal axis, said rotor comprising at least two magnetic portions separated by a non-magnetic portion which extends through the rotor at an angle inclined with respect to said longitudinal axis, thereby dividing said rotor, two elements of non-magnetic material at each end of the rotatable shaft, a stato…
