Abstract

Systems and methods provided herein relate to optimization of the motor of a pump system. Voltage-frequency ratios are adjusted while maintaining pumps speed in a systematic manner to lower power usage. Oscillations of the motor speed are detected, and voltage-frequency ratios adjusted to maintain low levels of oscillations while lowering power usage. Savings resulting in the optimization of the pump system are estimated.
