Concealed electrical door operator |
摘要 |
A door assembly includes a first door skin, a second door skin spaced apart from the first door skin and a door operator disposed between the first door skin and the second door skin. An arm extends from the door operator. The door operator includes a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position. A current sensor generates a current signal corresponding to the current to the motor. A position sensor in communication with the door arm generates a position signal corresponding to the position of the door relative to the frame. A controller communicates with the sensor and the motor. The controller controls a motor current to the motor in response to the current signal and the position signal. |
