Claim 3:
4. A method of controlling an aircraft oil management system, the method comprising:
outputting three-phase power from a generator that is mechanically coupled to a prime mover via a rotor shaft;
delivering oil to the generator using a pump that is mechanically decoupled from the rotor shaft;
driving the pump independent of a rotational speed of the rotor shaft using a pump control system by mechanically coupling the pump to a motor, outputting power from a motor power supply to one or both of the motor and a motor drive module, and controlling operation of the motor using the motor drive module;
measuring an operating condition of the generator using at least one sensor in signal communication with the motor drive module; and
outputting a sensor signal indicative of the measured operating condition,
analyzing, via the control system, a look-up table (LUT) that indexes at least one operating parameter of the generator to a target oil flow to be input to the generator;
comparing at least one index operating parameter and the measured operating condition indicated by the sensor signal indicative output from the at least one sensor; and
actively controlling the pump based on the comparison.
