  • Electrical actuating drive
    Patent number: 8581458
    Abstract: The present invention relates to an electrical actuating drive (1) for devices to be adjusted mechanically, having an electrical drive motor (2) and an output-drive shaft (4) which can be adjusted over a rotation actuating range of more than 360°, comprising an integrated contactless sensor angle measurement system (6) for determining and feeding back the respective rotation position of the output-drive shaft (4). The sensor angle measurement system (6) produces an output signal which largely simulates the characteristics of a conventional multiple potentiometer system.
