Document Type and Number:

Japanese Patent JP2014005832

Kind Code:

A

Abstract:

To provide an electrical machine preferable for a turbocharger which overcomes disadvantages of a prior art.

An electrical machine coupled to a compressor having a rotatable shaft comprises: a rotor forming a part of the rotatable shaft and having at least two magnetic portions separated by an inclined non-magnetic portion and two elements 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 that project inwardly towards the rotor by defining a second annular gap therebetween.
