  • Horizontally movable portal closure system
    Patent number: 6507160
    Abstract: A system and method for moving a horizontally sliding portal closure includes a linear reluctance motor or a magnetic stepper motor and a reaction piece. The reaction piece is attached to the portal closure such that activation of the stationary mounted linear induction or magnetic stepper motor causes movement of the reaction piece which, in turn, opens or closes the portal closure.
