STATIONARY MAGNET VARIABLE RELUCTANCE MAGNETIC SENSORS

摘要

A position sensor for sensing whether a rotatable element is in at least a first rotational position or a second rotational position is provided. A rotor is configured to be coupled to the rotatable element for rotation therewith, and is constructed at least partially of a magnetically permeable material and includes a first rotor pole. A stator is non-rotationally mounted, is constructed at least partially of a magnetically permeable material, is spaced apart from the rotor, and comprises a first main pole and a first stealer pole. The first main pole and the first stealer pole are spaced radially apart from each other. A magnet is non-rotationally disposed adjacent to the stator and is spaced apart from the rotor. A first magnetic sensor is non-rotationally mounted between the stator and the rotor, is disposed adjacent the first main pole, and is radially offset from the first stealer pole.
