Abstract
An electrical machine (22) incorporates foil bearings (24) which are radially interposed between the stator assembly (26) and the permanent magnet of a rotor shaft (12), thus reducing the required axial length of the shaft and increasing the rotational speed at which the shaft bends incident to resonance.
