Device and method for controlling elevator car door

摘要

An elevator car has an access opening, a car door for closing the access opening, which door has at least one door panel that can be displaced parallel to the access opening, a thrust crank drive for displacing the at least one door panel between an open position and a closed position, an electric motor for driving the thrust crank drive, and a control device for actuating the electric motor. The control device actuates the electric motor so that a displacement velocity of the at least one door panel is substantially constant over the entire displacement path between the open position and the closed position of the door panel.

主权项

1. An elevator car with an access opening, a car door for closing the access opening, the car door having at least one door panel displaceable parallel to the access opening, a thrust crank drive for moving the at least one door panel between an open setting and a closed setting, an electric motor for driving the thrust crank drive, and a control device for controlling the electric motor, comprising:
the control device being programmable and connected to the electric motor and controlling operation of the electric motor by determination of an instantaneous motor rotational speed and/or an instantaneous motor torque of the electric motor and including kinematics of the thrust crank drive to generate a movement speed of the at least one door panel and to vary the instantaneous motor rotational speed and/or the instantaneous motor torque of the electric motor to maintain the movement speed substantially constant over an entire movement path between the open setting and the closed setting of the door panel.
