Abstract
Systems and methods for determining proper phase rotation in a linear motor that may be used in an ESP system, where the phase rotations associated with power and return strokes are initially unknown. The method includes providing power to the motor for multiple cycles and monitoring the load (e.g., by monitoring current drawn by the motor) on the motor to determine in which direction (phase rotation) the load on the motor increases. This direction corresponds to the power stroke of the motor. The direction of increasing load is then associated with the power stroke and the motor is operated normally.
