What is claimed is: 1. A method for operating a gas turbine engine, comprising the steps of: providing the gas turbine engine, the engine having a main shaft drivingly connected to a multiple power output channel electric machine, the machine having a single rotor and a single stator, the stator being a cylinder composed of a plurality of non-overlapping sectors, each sector having a set of stator windings associated therewith, each set having at least one primary and one secondary windings in the sector, the at least one secondary winding adjacent to and electrically isolated from the at least one primary winding, the stator sector primary windings being electrically independent of one another, the stator sectors primary windings each providing one of said multiple power output channels; providing an electrical distribution system electrically connected to said power output channels of the machine, the channels connected to the electrical distribution system in parallel to one another; operating the engine to rotate the rotor and thereby generate electricity; in normal machine operation, combining the power output channels to provide a single power output to the electrical distribution system; and in the event of a fault in a said stator sector, manipulating electricity in the secondary winding of the faulted sector to increase the impedance of the faulted sector and thereby reduce current output of the at least one primary winding of the channel associated with said faulted sector while continuing operation of a remainder of said channels to provide power output to the electrical distribution system. 2. The method as defined in claim 1, wherein in normal operation, the power output of each channel provides substantially equal current output to the electrical distribution system. 3. The method as defined in claim 1, wherein two channels are provided, the power output of each channel in normal operation providing substantially half of a current output provided to the electrical distribution system. 4. The method as defined in claim 1, wherein the electrical distribution system comprises redundant engine accessory systems. 5. The method as defined in claim 1 further comprising providing electricity from the electrical distribution system to at least one of the group consisting of a plurality of power conditioning units, a plurality of engine pumps, and a plurality of electrically-run accessories. 6. The method as defined in claim 1, further comprising the step of open-circuiting the at least one secondary winding of said at least one channel associated with said fault to thereby reduce electrical output of the at least one primary winding of said channel. 7. The method as defined in claim 1, wherein three primary windings are provided in a 3-phase configuration in each said sector. 8. The method as defined in claim 1, wherein each channel is connected to the electrical distribution system via a corresponding primary circuit terminal. 9. The method as defined in claim 2, further comprising increasing the output of a remainder of the channels to provide an output current substantially equal to a current level of the machine in normal operation prior to the fault. 10. The method as defined in claim 3, the power output of the non-faulted channel providing substantially twice a current output level provided by the channel prior to the fault.
