Abstract
A method for analyzing signals from an angle sensor including at least two sensing elements which span a plane and including a rotatable element for varying the plane, the element being spaced from same. The angle sensor also includes a brushless electromotor which is controlled according to the method. The method for analyzing signals from an angle sensor comprises at least two sensing elements, said method producing high-definition measured results using sensing elements that map a full circle. This is achieved in that the sensing elements capture at least one first and one second vector of the field lying on the plane, the vectors being linearly independent of each other. A further variable, which is dependent on the distance between the plane and the rotatable element, is additionally detected, and the amplitudes of the signals of the first and the second sensing elements are controlled with the value of the further variable.
