A method of integrating an electric motor or generator as part of an aircraft engine shaft. The motor is used to rotate the rotor so as to cool the rotor in a temperature gradient. The generator is used to provide power to the aircraft. In one or more examples, a power generation device includes a gas turbine engine including a rotor shaft and a first casing around the rotor shaft; a transmission connecting the rotor shaft to a gearbox, the transmission comprising a drive shaft and a second casing around the drive shaft; and a brushless DC motor integrated with the engine and including one or more permanent magnets and one or more coils.
