ABSTRACT:
A system and method for controlling an electric motor is disclosed. The method comprises determining the operating load of the electric motor and then calculating the voltage to be applied to the electric motor in response to the operating load. The voltage to be applied operates the motor in an efficient manner for the given load. The frequency of the voltage to be applied to the electric motor is calculated in response to the operating load such that the frequency of the voltage to be applied operates the motor in an efficient manner. Power is applied to the motor with the voltage and frequency calculated in order to operate the motor in an efficient manner for the given load.
