Abstract
Embodiments of the invention relate to arrangements for connecting together elements of an electric motor or generator such as a rotor or stator. The rotor (607) or the stator (601) may each include a first component (605/610) that has a common circumference with a corresponding second component (602/608). In order to connect the first and second components together the first component has one or more recesses or grooves (7/47) distributed around the circumference and the corresponding second component has one or more resiliently deformable protrusions (606/611). The resiliently deformable protrusions are arranged to protrude into the one or more recesses so as to press against side walls of the recesses and resist relative rotation of the first and second components.
