Abstract
High-resolution multi-turn sensing apparatus and methods. A method can be implemented to sense a rotational position of a shaft having a longitudinal axis. Such a method can include determining a turn number of the shaft with a first magnet arranged in a non-contact manner with a first magnetic sensor to allow measurement of a linear position of the first magnet relative to the first magnetic sensor. The linear position can be representative of a turn number of the shaft. The method can further include determining an angular position of the shaft within a given turn with a second magnet positioned at an end of the shaft along the longitudinal axis and arranged relative to a second magnetic sensor. The method can further include combining the turn number with the angular position to generate one or more output signals representative of a measured rotational position of the shaft.
