ABSTRACT:
A DC machine having a primary and a secondary for generating electromagnetic movement of the secondary. The primary incorporates a plurality of parallel conductive segments arranged side-by-side along the direction of secondary movement. As the secondary moves with respect to the primary, commutating strips mounted on the secondary commutate the conductive segments of the primary according to a sequence in which successive groups of the conductive segments are interconnected to form series or parallel excitation windings. The succession of excitation windings serves to induce continuous electromotive force between the secondary. The arrangement is especially suited for a linear motor having non-returning armature windings, but may be in rotary machines as well.
