Title: SENSOR ERROR DETECTION AND CORRECTION
Abstract:
The present techniques generally relate to electric motor which may include one or more sensors usable to determine rotor alignment and/or speed. A method and apparatus for rotor alignment and/or speed error detection and/or correction are proposed, such as using signals from one or more sensors. A method and apparatus for controlling stator tooth activation based, at least in part, on corrections and offsets is also disclosed.
