Abstract

A system including an encoder, multiple sensing elements and control logic. The encoder has a pole pitch and is configured to rotate in a direction of rotation. The multiple sensing elements are situated along the direction of rotation and span at least half the length of the pole pitch. The control logic is configured to receive signals from the multiple sensing elements based on the encoder in a static position and obtain a switching point based on the signals.
