Abstract:
A motor system includes a motor including two linear Hall sensors configured to output analog signals, and a controller configured to control the motor. The controller is operable to monitor the analog signals output from the two linear Hall sensors, determine a plurality of auxiliary signals based on the analog signals, and determine a motor position based on the plurality of auxiliary signals.
