Abstract

The invention relates to a magnet assembly having a magnet ring (1), which is attached to a shaft by means of a support sleeve (2), particularly for a torque and/or rotational angle sensor arrangement. The magnet ring (1) is connected to the support sleeve through at least one intermediate piece (10; 23, 24) in a positive-locking and/or bonded manner so that the magnet ring lies radially above the support sleeve (2), wherein in each case tooth geometries and/or undercut geometries are arranged on the magnet ring (1) in such a way that said geometries are molded as an injection-molded part by way of application of the at least one intermediate piece (10; 23, 24).
