Abstract

A wedging arrangement for a rotating electrical machine is disclosed. The machine comprises a plurality of teeth 16, the teeth defining a plurality of slots 18 for accommodating windings 20. The wedging arrangement includes a wedge 28 for closing the slots. The geometry of the wedge 28 is designed to interact with the teeth 16 to counteract a force which pushes adjacent teeth apart.
