摘要 |
An electromagnetic machine for extracting power from a turbine engine (10) includes an outer rotor (76) and an inner rotor (72) rotatably supported adjacent to a stator (66). The stator (66) is disposed between the inner (72) and outer (76) rotors. The stator (66) has an inner set of windings (67) disposed on an inner surface adjacent to the inner rotor (72), and an outer set of windings (65) on an outer surface of the stator adjacent to the outer rotor (76). A plurality of permanent magnets (75) are disposed on an inner surface of the outer rotor (76) element and on an outer surface of the inner rotor element (72). Air gaps (62, 64) are defined between the outer surface of the stator (66) and the outer permanent magnets (75), and between the inner surface of the stator portion (66) and the inner permanent magnets (74). The inner stator windings (67) form a set of multiple-phase windings, and the outer stator windings (65) form a set of multiple-phase windings. |
