摘要： A system for generating supplemental electrical power from the low-pressure (LP) turbine spool of a turbofan engine includes a high-speed, high magnetic pole count, generator, a gearbox, a controller and a power converter. The LP turbine spool is mechanically coupled to the generator portion by the gearbox for driving the generator portion. The controller portion has a speed-sensing element for sensing the LP turbine speed. The controller portion disables the power converter when the generator exceeds a predetermined speed, and enables the power converter when the generator portion is less or equal to the predetermined speed. The effective load on the generator is reduced to approximately zero when the LP turbine spool exceeds the predetermined speed, permitting the generator to be electrically bound up to the predetermined speed and mechanically bound in excess of the predetermined speed.

摘要： An electric machine is disclosed comprising a first energy source, a second energy source, and a stator which comprises a first set of windings and a second set of windings. The electric machine has a rotor and a controller, the controller configured to control the first energy source to supply a first current to the first set of windings and control the second energy source to supply a second current to the second set of windings. The controller also detects an angular position of the rotor, detects the first current, detects the second current, and determines an optimum phase shift angle of the first current based on the angular position of the rotor, the first current, and the second current. The controller controls the first energy source based on the optimum phase shift angle to modify the first current supplied to the first set of windings.
