Abstract

An external rotor for an electrical machine. The rotor comprises a plurality of permanent magnets, a plurality of backing segments and support structure, the permanent magnets arranged circumferentially to form poles of the rotor, and the plurality of backing segments arranged radially outside the permanent magnets to provide a flux path between the poles and to provide an abutment to at least radially locate the permanent magnets. Each backing segment is retained by the support structure.
