Abstract
A measuring device for contactless detection of an angle of rotation is comprised of a supporting plate ( ) made of soft magnetic material which is used as a rotor. In a plane in relation to the supporting plate ( ), two segments ( ) are disposed, which are separated by means of a slot ( ) and a spacer gap ( ). The supporting plate ( ) is fastened to an axle ( ) whose extension ( ) or the axle ( ) itself is comprised of a magnetically conductive material. The extension ( ) protrudes into one of the segments ( ) of the stator. The axle ( ), particularly its extension ( ), the supporting element ( ), and the segments ( ) control the magnetic flux of the permanent magnet ( ) disposed on the supporting plate ( ). Through the inclusion of the axle ( ) into the magnetic flux, the measuring device is constructed in a relatively simple and space-saving manner.
