  "textContent": "A permanent magnet alternator (42) includes a permanent magnet alternator stator (78) attached to a housing (64). A shaft (46) is rotatable with respect to the housing with a permanent magnet alternator rotor (76) attached to the shaft. The permanent magnet alternator rotor is positioned with respect to the permanent magnet alternator stator so as to generate electricity when the shaft rotates. A cooling fan (44) is also attached to the shaft and is positioned in a gas flow path (54) for flowing air through the gas flow path. The cooling fan (44) is arranged to flow air over a heat exchanger which is fluidically connected to a gas turbine engine lubrication circuit.",
