Abstract

See full text

A sense magnet assembly including a generally circular hub portion defining a central axis. The hub portion includes a generally disk-shaped base portion and an outer wall extending axially from an outer edge of the base portion. An elastic magnet material is provided including a plurality of annular portions positioned at radially spaced locations. A substantially rigid annular divider formed of a non-magnetic material is located between adjacent pairs of the annular portions of the magnet material, and a rigid cover is provided extending over the magnet material to limit movement of the magnet material in response to centrifugal forces.
