Sensor device for detecting the rotation angle of the components of rotary motion

The present invention relates to a sensor device for detecting the rotation angle of the components of rotary motion (5) (α) (1). Sensor device comprises a N-pole region (N) and S at least one permanent magnet and a pole region (S) (M1, M2), and the axis of rotation of components of rotary motion (5) (3 relative), predetermined first radial distance (R) measured value generator which is spaced (10), detecting at least one magnetic characteristic quantity, and, components for rotary motion (5) of the rotary shaft relative to (3), a predetermined second radial least one is arranged at a distance of the sensor element (a) measurement detector with a (20) It is equipped with a. By movement of the components of rotary motion (5), the change of the at least one magnetic characteristic variables can be evaluated to determine the rotation angle (alpha) is generated. At least one permanent magnet (M1, M2) are rotated shaft (3) in the center, or are magnetized along the arc (B) defined by the distance of the first radial (R), or an arc ( It is magnetized in the tangential direction of B), and to form the magnetic vector perpendicular detection plane with respect to the magnet surface. According to the present invention, the measured value generator (10) comprises at least two permanent magnets (M1, M2), has at least one multi-pole magnet (MP). At least two permanent magnets (M1, M2) are arranged so that the end portion that is opposite to the permanent magnets (M1, M2) adjacent directly in the multi-pole magnet (MP) have the same magnetization (S) It is.
