ABSTRACT:
An angle-of-rotation sensor comprises a coil, a magnetically conductive element within the coil which is rotatable around an axis of rotation, the axis of rotation of the magnetically conductive element being at least partially within the coil, and a single winding for the coil. The angle-of-rotation of the magnetically conductive element is determined by measuring the change in self-inductance in the coil when the magnetically conductive element is caused to rotate.
