Abstract:
1. An angle sensor for determining an angle between a sensor system and a magnetic field, the angle sensor comprising: a magnet that is adjustable in different rotational positions relative to the sensor system with regard to a rotation axis; a first magnetic field sensor configured to detect a first magnetic field component, which is oriented transversely to the rotation axis; a second magnetic field sensor configured to detect a second magnetic field component, which is oriented transversely to a plane extending from the rotation axis and the first magnetic field component, the second magnetic field sensor intersecting at a right angle with the first magnetic field sensor; and a third magnetic field sensor configured to detect a third magnetic field component, which is oriented in the direction of the rotation axis, the third magnetic filed sensor positioned adjacent to an intersection of the first and second magnetic field sensors, wherein said third magnetic field component is substantially constant during rotational movement of the magnetic field.
