Abstract
For simpler manufacture of a rotation angle sensor and to utilize as much of its angle expansion as possible, the partial stator elements are in the shape of a partial ring split into a large partial stator element (22.1) and a small partial stator element (22.2) with tangentially arranged spacing openings (4, 5) located between them. The large partial stator element (22.1) covers a range of greater than 180° and the small partial stator element a range of less than 180° of a circular arc. The large and small stator elements (22.1, 22.2) are at least partially molded into one of the parts made of a magnetically non-conducting material. A magnet element consists of two magnetically bipolar partial magnet segment elements that are essentially of the same length and cover 90° or more of a circular arc.
