Abstract:
An apparatus for effecting non-contact linear door displacement comprising a tubular motor formed of a stator (1) formed from a plurality of magnets (21) arranged along a linear axis (15), and at least one thrust block (3) each formed of at least one electrically conductive coil encircling the stator (1) at a distance sufficient to facilitate electro-mechanical interaction between the plurality of coils and the stator (1), at least one door (5) attached to at least one of the plurality of thrust blocks (3) via a hanger (9) and the at least one door (5) capable of a movement in the direction of the linear axis (15), a rolling component (11) to enable movement of the hanger (9) in the direction of the linear axis (15), and a control mechanism (70) for sensing the position of each of the at least one door (5) and issuing an electrical control signal to each of the plurality of thrust blocks (3) so as to affect the movement of the at least one door (5).
