Concealed electrical door operator
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.
1. A door assembly comprising:
a door frame;
a door in the door frame, the door comprising,
a first door skin; and
a second door skin spaced apart from the first door skin;
a door operator disposed between the first door skin and the second door skin; and
an arm extending from the door operator,
wherein said door operator comprises:
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 generating a current signal corresponding to the current to the motor;
a position sensor in communication with the arm generating a position signal corresponding to the position of the door relative to the door frame;
a controller communicating with the current sensor, the position sensor and the motor, said controller controls a motor current to the motor in response to the current signal and the position signal; and
the controller generates a braking current when a speed of the door is greater than a desired speed of the door for a predetermined position of the door.
2. A door assembly as recited in claim 1 wherein the controller increases the motor current to obtain a predetermined movement speed.
3. A door assembly as recited in claim 1 wherein the controller changes the motor current based on the position signal.
4. A door assembly as recited in claim 1 wherein the controller changes the motor current based on the position signal at least three times between the open position and the closed position.
5. A door assembly as recited in claim 1 further comprising a latch operator in communication with the controller, said controller controlling the motor current in response to the latch operator signal.
6. A door assembly as recited in claim 5 wherein the latch operator is disposed within the door.
7. A door assembly as recited in claim 1 further comprising an access controller in communication with the controller, said access controller enabling opening of the door.
8. A door assembly as recited in claim 7 wherein the access controller is disposed at least partially within the door.
9. A door assembly as recited in claim 1 further comprising a proximity sensor disposed between the first door skin and the second door skin, said proximity sensor generating a proximity signal corresponding to an object approaching the door, said controller controlling the motor current in response to the proximity signal.
10. A door assembly as recited in claim 1 further comprising an environmental sensor in communication with the controller, said environmental sensor generating an environment signal.
11. A door assembly as recited in claim 10 wherein the environment sensor comprises at least one of a smoke sensor, a toxic agent sensor, a light sensor and a heat sensor.
12. A door assembly as recited in claim 1 wherein the door operator comprises a power source disposed between the first door skin and the second door skin.
13. A door assembly as recited in claim 12 wherein the power source comprises a battery.
14. A door assembly as recited in claim 1 wherein a first end of the arm is rotatably coupled to the door assembly and a second end of the arm is slidably coupled within a channel coupled to a door frame.
15. A communication comprising:
a central controller; and
the door assembly as recited in claim 1 ,
wherein the door assembly comprises a communication interface for communicating with the central controller.
16. The door assembly of claim 1 , wherein the door operator further comprises a gear set, and
the motor and the gear set are not oriented axially around the same axis.
17. A door assembly comprising:
a frame;
a door in the door frame, comprising
a first door skin; and
a second door skin spaced apart from the first door skin;
a door operator disposed between the first door skin and the second door skin; and
an arm extending from the door operator,
wherein said door operator comprises:
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 generating a current signal corresponding to a current to the motor;
a position sensor generating a position signal corresponding to a position of the door relative to a door frame;
a controller communicating with the current sensor, the position sensor and the motor, said controller controlling a motor current to the motor in response to the current signal and the position signal; and
the controller increases the current to the motor when a speed of a door is less than a desired speed of the door for a predetermined position of the door.
18. The door assembly of claim 17 , wherein the door operator further comprises a gear set, and
the motor and the gear set are not oriented axially around the same axis.
