Abstract
An actuating drive (60), that can be fed by a battery (6), for an actuator (5) comprises a drive unit (61) for operating the actuator (5), and a control unit (62), capable of communicating with an external station (70) in a wireless fashion, for controlling the drive unit (61). The control unit (62) can be fed via a voltage regulator (64) connected to the battery (6), while the drive unit (61) is directly connected to the output voltage (UB) of the battery (6). The energy consumption of the actuating drive (60) can be optimized in order to achieve a long service life for the battery.
Claims11
A drive device for an actuator, operable to receive operating power from a battery, the drive device comprising:
- a drive unit configured to operate the actuator, and
- a control unit, capable of communicating with an external station in a wireless fashion, configured to control the drive unit,
- wherein the drive unit has an electric motor configured to be controlled by the control unit, and a driver unit for the electric motor, wherein the control unit can be fed via a voltage regulator connected to the battery, and wherein the drive unit is directly connected to the output voltage of the battery;
- and
- wherein the control unit is configured to generate a control signal (m) for the driver unit such that a speed of the electric motor is controlled to a constant value (ωs).
