Abstract
A rotational angle sensor includes a stator element and a rotor element. The rotor element is mounted to rotate about a rotation axis. The stator element has a transmitter coil and a receiver coil that are arranged on a circuit board. The receiver coil substantially encloses the rotation axis in a circumferential direction and is formed by a plurality of adjacent partial windings. The partial windings are each formed from sections of two circular-arc-shaped conductor paths curved to the left and two circular-arc-shaped conductor paths curved to the right. A first conductor path curved to the right extends through a first point on a first circle, a second point on a third circle and rotated relative to the first point by a quarter of a measuring range of the sensor, and a third point on a second circle and rotated relative to the first point by half the measuring range.
