A New Door Driving System Realizing Quick and Silent Motion
Thursday 1st October 1998
We have developed a new door driving system which opens and closes elevator doors smoothly and silently. For a smooth door motion we developed a new gripping link mechanism which is catch the floor doors with a minimum of motion. To design this link mechanism we used a static analysis method. For a silent door motion, we developed a new AC-motor controller which reduces the electric current distortion and the torque ripple of the AC-motor to make it work more quietly.
