<p>A magnetic rotational position sensor (10) senses each rotational position of a control shaft (20) about a first rotational axis over a definable range of rotation of the control shaft. The magnetic rotational position sensor (10) includes a magnetic circuit (13), a magnetic flux sensor (14), a drive circuit, and an output signal amplifier. The magnetic circuit (13) encloses an equally balanced magnetic field, and is adjoined to the control shaft (20) to synchronously rotate the magnetic field about a second rotational axis. The magnetic flux sensor (14) is disposed within the magnetic field to sense each rotational position of the control shaft (20) as the control shaft is rotated about the first rotational axis over the definable range of rotation. <IMAGE></p> |
