Abstract

An actuating drive, which can be remotely controlled in a wireless fashion and is fed by a battery, for operating an actuator (5) between two final positions has a control device for controlling the speed of an electric motor (1). The actuating drive (60) has a changeover device (81) with the aid of which it can optionally be operated either in a first operating mode or in a second operating mode. The control device controls the speed to a first setpoint (ω_SN) in the first operating mode, and to a second setpoint (ω_SL) in the second operating mode. The first setpoint (ω_SN) is fixed in such a way that the energy consumption during operation of the actuator (5) is minimal, while the second setpoint (ω_SL) is fixed in such a way that the noise level (L) generated by the actuating drive in the second operating mode is lower than in the first operating mode. By programming a time controller (84) in a fashion appropriate to the application, the actuating drive (60) operates whenever possible in an optimum fashion in terms of energy and, when actually necessary, at the low noise level (L). The actuating drive (60) can therefore be used in a fashion saving battery energy even in the domestic sector.

Claims

1. An actuating drive comprising:

an electric motor for operating an actuator between two final positions, and

a control device for controlling the speed of the electric motor,

wherein the actuating drive can optionally be operated, via a changeover device, either in a first operating mode or in a second operating mode, and in that the control device is configured to control the speed to a first setpoint in the first operating mode, and to a second setpoint in the second operating mode, the first setpoint being fixed in such a way that the energy consumption during operation of the actuator from a first final position into a second final position is minimal, and the second setpoint being fixed in such a way that a noise level generated by the actuating drive in the second operating mode is lower than in the first operating mode.

2. The actuating drive as claimed in claim 1, wherein that the second setpoint is lower than the first setpoint.

3. The actuating drive as claimed in claim 1, wherein the actuating drive includes a transceiver unit configured for wireless communication with a device separated from the actuating drive, and wherein the changeover device of the actuating drive is configured to be controlled from the separate device.

4. The actuating drive as claimed in claim 1, wherein the operating mode of the actuating drive is configured to be controlled as a function of the time of day via a time controller.

5. The actuating drive as claimed in claim 3, wherein the operating mode of the actuating drive is configured to be remotely controlled via a radio link.

6. The actuating drive as claimed in claim 4, wherein the time controller has a daily cycle structure.

7. The actuating drive as claimed in claim 4, wherein the time controller has a weekly cycle structure.

8. An actuating drive comprising:

an electric motor for operating an actuator between two final positions, and

a control device for controlling the speed of the electric motor,

wherein the actuating drive can optionally be operated, via a changeover device, either in a first operating mode or in a second operating mode, and in that the control device is configured to use closed-loop control to control the speed to a first setpoint in the first operating mode, and to a second setpoint in the second operating mode, the first setpoint being fixed in such a way that the energy consumption during operation of the actuator from a first final position into a second final position is minimal, and the second setpoint being fixed in such a way that a noise level generated by the actuating drive in the second operating mode is lower than in the first operating mode.

9. The actuating drive as claimed in claim 8, wherein the actuating drive includes a transceiver unit configured for wireless communication with a device separated from the actuating drive, and wherein the changeover device of the actuating drive is configured to be controlled from the separate device.

10. The actuating drive as claimed in claim 9, wherein the operating mode of the actuating drive is configured to be controlled as a function of the time of day via a time controller.

11. The actuating drive as claimed in claim 10, wherein the operating mode of the actuating drive is configured to be remotely controlled via a radio link.

12. The actuating drive as claimed in claim 10, wherein the time controller has a daily cycle structure.

13. The actuating drive as claimed in claim 10, wherein the time controller has a weekly cycle structure.
