Abstract
A position sensor assembly including a circular-shaped or rhombus-shaped magnet and at least one magnetic flux density sensor, such as a Hall effect sensor, wherein rotation of the magnet is detected by the at least one sensor. The magnet may be positioned coaxially with the longitudinal axis of a rotor shaft of a motor and provided within a support. A position extraction algorithm may be employed using the output from the sensors to detect the position of the rotor shaft.
