Permanent magnet for a sensor arrangement for determining an angular position of the permanent magnet

摘要

The present invention relates to a permanent magnet for a sensor arrangement for determining an angular position of the permanent magnet, wherein end faces of the permanent magnet in each case in an x - y - plane, and a central axis transverse to the x - y - plane and coaxially with respect to an axis of rotation of the permanent magnet; wherein the permanent magnet has exactly two poles, which in the x - y - plane on opposite sides of the permanent magnets are arranged, so that the permanent magnet is magnetized diametrically; wherein the permanent magnet is arranged coaxially to the central axis having an opening; wherein an inner circumferential surface and an outer peripheral surface of each of which extend parallel to the central axis; wherein an outer periphery of each cross section parallel to the x - y - plane, a shape different from a circular shape.
