Abstract
An actuating device including a drive device and a monitoring device. The drive device includes an adjusting assembly which can be moved along a straight movement line and which has an adjusting body and a magnetic adjusting element that can be rotatably mounted on the adjusting body. The monitoring device includes a sensor device which is used to detect at least one position of the magnetic adjusting element along the straight movement line. The monitoring device has a magnetic aligning assembly which is arranged such that the adjusting element assumes a specified rotational position relative to the sensor device on the basis of a magnetic interaction between the adjusting element and the aligning assembly.
Claims12
An actuator apparatus having a drive device and a monitoring device, wherein the drive device comprises an actuator arrangement, which can be displaced along a movement straight line, the actuator arrangement having an actuator body and a magnetic actuator element rotationally mounted on the actuator body, and wherein the monitoring device comprises a sensor device, which serves to detect at least one position of the magnetic actuator element along the movement straight line, and wherein the monitoring device comprises a magnetic alignment arrangement, which is arranged in such a way that the actuator element adopts, on account of a magnetic interaction between the actuator element and the alignment arrangement, a predetermined rotational position relative to the sensor device.
