Angular position sensor |
摘要 |
An angular position sensor employs a pair of magnets that are disposed on a rotating cylinder at opposite ends of a diameter of the cylinder. A hall-effect flux sensor is fixed within the cylinder and offset from a line of geometric and magnetic symmetry between the magnets. The offset sensor detects a linear change in flux of the magnets as the magnets rotate with the cylinder over a predetermined angular distance and thereby determines the angular position of the cylinder. The offset of the sensor is adjusted to reduce the sensing error.
