Classification: CPC F  H  B | IPC F

Claim 0:
1. An aircraft oil management system comprising:
a generator mechanically coupled to a prime mover via a rotor shaft, the generator configured to output a three-phase power;
a pump mechanically decoupled from the rotor shaft and configured to deliver oil to the generator; and
a pump control system configured to drive the pump independent of a rotational speed of the rotor shaft, the pump control system comprising:
a motor configured to drive the pump;
a motor drive module configured to control operation of the motor;
a motor power supply configured to power one or both of the motor drive module and the motor; and
at least one sensor in signal communication with the motor drive module, the at least one sensor configured to measure an operating condition of the generator and to output a sensor signal indicative of the measured operating condition,
wherein the motor drive module is configured to store 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, and wherein the motor drive module is configured to actively control the pump based on a comparison between the at least one index operating parameter and the measured operating condition indicated by the sensor signal indicative output from the at least one sensor.
