Classification: CPC F | IPC F

Claim 7:
8. A permanent magnet generator, comprising:
a stator;
a rotor which rotates with respect to the stator;
a turbine connected to the rotor; and
a housing that contains the stator, the rotor, and the turbine, the housing in communication with a recirculation conduit such that a working fluid from the recirculation conduit drives the turbine which drives the rotor, wherein the working fluid is fuel; and
the permanent magnet generator in communication with the recirculation conduit such that the working fluid from the recirculation conduit drives the permanent magnet generator, the working fluid thermally coupled to the permanent magnet generator through a cooling path formed within the housing, the cooling path formed within the housing configured to circulate the working fluid through the cooling path providing thermal management of the permanent magnet generator.
