Abstract
In an inductive position sensor for determining the position, particularly the rotation angle, of a movable element, at least two subsystems are provided, which each have second transmitting units with an actuating unit, an oscillating circuit on the movable element, and a receiving unit with an evaluating unit. According to the invention, it is provided that the operation of the individual subsystems is carried out alternately. Thus, if one subsystem is operating, all other subsystems are deactivated. In this way, all subsystems are individually operated in a consecutive manner. The synchronization required to do so is provided by a non-galvanic coupling of the subsystems, and in particular by an inductive coupling by way of preferably existing inductances of the subsystems.
