GAS TURBINE ENGINE AND ELECTRIC MACHINE

摘要

An electric machine is disclosed integrated to rotate with a shaft of a gas turbine engine. In one form the electric machine is integrated with a fan of the gas turbine engine. A rotor of the electric machine can be disposed at the end of the fan blades and the stator integrated into a flow path forming surface of the gas turbine engine. In one form the windings of the electric machine can change configuration permitting some windings to be placed in parallel with one or more other windings, and then connected together in series with remaining windings, if any. The voltage of the electric machine can change as a result of a change in configuration of the windings. A moveable member can also be used to alter a magnetic field produced from the electric machine when operated such that a voltage can be changed as a result of altering the magnetic field.
