Abstract

A single phase or multiphase dynamo electric machine including a stator member having at least one winding arranged to be energized to provide an alternating flux, and a further member, e.g. a rotor, movable with respect to the stator and having at least one short circuited winding providing at each position of the movable member alternative paths of low and high reluctance to the passage of alternating magnetic flux, sensing means for sensing the relative position of the two members, switching means actuated by the sensing means to cause the movable member to lock in position relative to the stator at a null position and to effect successive energization of the stator winding at other than the null position to effect continuous movement of the movable member past the stator.
