Abstract:
A magnetic rotational position sensor for sensing each rotational position of a control shaft about a first axis over a definable range of rotation. The position sensor generally includes a magnetic circuit and a pair of magnetic flux sensors. The magnetic circuit is comprised of a ring pole piece defining an air gap area and a magnet disposed within the air gap area. The ring pole piece and the magnet cooperate to produce a magnetic field within the air gap area. The magnetic circuit is adjoined to the control shaft to synchronously rotate the magnetic field about a second axis. The pair of magnetic flux sensors are disposed within the magnetic field to sense each rotational position of the control shaft as the control shaft is rotated about the first axis over the definable range of rotation.
