It is an automatic door, which is driven with a motor and a speed sensor, and is to be controlled with a servo-device. Upon the door being opened or closed and being stopped by an obstacle or being out of order, the motor to drive the door will be stopped; in case of the door being retarded by a wind force or other factors, the driving power of th motor will automatically be adjusted to such an extent that the door can still be closed together so as to fully use the driving power of the motor. |
