Abstract: An axial flux machine comprising a rotor mounted about an axis of rotation and having two axial faces. A first stator ring is positioned on the rotor adjacent to a first axial face, to define an air gap, between the first stator ring and first axial face. The first stator ring is formed by stator ring segments, each having a radially inner and outer edge. A second stator ring is positioned on another side of the rotor, adjacent to the second axial face, to define an air gap between the second stator ring and second axial face. The second stator ring is, also, formed by stator ring segments, each having a radially inner and outer edge and corresponding to a first stator ring segment. The stator ring segments are deflectable in unison in response to axial deflection of the rotor, to maintain the air gaps, due to link elements.

Abstract: A rotating electrical machine comprises a rotor having an axis of rotation and a stator assembly surrounding the rotor. The stator assembly comprises a plurality of circumferentially arranged stator segments and a plurality of link elements of which at least one link element extends between each of the circumferentially adjacent stator segments. Each link element provides a rigid circumferential connection between circumferentially adjacent stator segments so that the linked stator segments form a torsionally stiff annular stator and also provides a radially flexible connection between circumferentially adjacent stator segments to permit relative movement between adjacent linked stator segments in the radial direction.
