MAGNET AND HOLDER ASSEMBLY HAVING IMPROVED ROTATIONAL AND AXIAL STABILITY
摘要
<p>A magnet held in a magnet holder is constrained against radial or axial instability, or against both, by a shape on either component in contact with complementary shape on the other component, the shaped components generally defining a tab-and-slot arrangement. The magnet component may be a bonded magnet and in one embodiment may be formed in place by injection molding. The magnet also will exhibit improved magnet properties when magnetized to have lines of polarity matching a path defined by the bulk of the magnetic material as governed by the location of tabs on the magnet. The invention is useful in magnet-sensor assemblies found in industrial applications and in automotive applications such as power steering systems.</p>
