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.
