  • Motor speed controller system for freight elevator doors
    Patent number: 7040457
    Abstract: A linear displacement potentiometer is mechanically tied to an elevator door/gate and provides a voltage corresponding to the door/gate position to a programmable controller. The programmable controller uses a software program to determine when the door/gate is fully open or fully closed. The program controls a variable speed motor drive to accelerate/decelerate the door/gate. When the linear displacement potentiometer determines the door/gate is at a predetermined location, the motor speed is reduced to a fixed value. When the door/gate position is nearly open/closed, the motor speed is decelerated to zero speed.
