Abstract

A method and system for controlling a motor. The embodiments herein relate to motors and, more particularly, to enabling a motor to run efficiently on available power supplies. Embodiments herein enable a motor to operate using multiple input power sources and intelligently utilize the best possible source at a given point of time. Embodiments herein enable a motor to be started from a compatible and/or incompatible source by eliminating motor inrush currents and thereby ensuring there are no stresses on the power source or the power conditioning equipment. Embodiments herein provide improved algorithms to improve efficiency levels when the equipment is operated from multiple input power sources. Embodiments herein provide for the power source equipment to be optimally sized without catering to motor inrush currents and higher energy consumption if the motor/multi-motor system were to be run without any information on change of input power source.
