Abstract

A stator for an electric machine comprises a tubular unslotted ferromagnetic flux collector ring (16) and stator winding coils (18, 19, 20) having two legs which extend substantially axially along the inner cylindrical surface of the flux collector ring (16). Each winding coil leg is confined within an envelope (22) of a thin, flexible, non-conductive non-magnetizable material which is impregnated with and bonded to the next legs as well as to the flux collector ring (16) by a hot-setting resinous material.
