Abstract
An electromagnetic device includes a stator having circumferential ribs which define grooves locating windings. An annular armature has internal ribs which extend into the grooves and the armature is divided along its length into at least two parts to enable assembly about the stator. The armature parts are secured at one end to an output member and at the other end are located by the wall of a surrounding body or a part carried thereby.
