Abstract
An electric motor that may be used in a remote location, such as in a wellbore for pumping production fluids. The electric motor is designed to permit real-time adjustment of the position feedback signals to optimize motor performance. A position sensor is coupled to the rotor to sense rotor position. Simultaneously, a parameter, such as shaft twist, is measured, and a feedback control signal is provided. A processor receives the position sensor signals and the feedback control signals, and adjusts the energization of the stator windings to optimize motor performance.
