摘要： A multi-sage controlled frequency generator is described that has a low size, weight and cost. The new generator requires an electronic controller that requires only 25% of the total generated power (100%) when the generator shaft speed varies by +/−25% around its synchronous speed. The shaft driving the generator in the direct-drive controlled frequency generator may be moved at a variable speed. The output frequency of the generator may be controlled by electrically controlling the frequency of the first stator stage and by selecting the control frequency, the number of poles, and the number of stages, such that the output of the last stage will be maintained constant at the desired grid frequency.

摘要： A high frequency starter-generator system uses an electric machine design that does not employ rotating rectifiers installed on the rotor. The output frequency of such a starter-generator is increased by about 200% as compared with a conventional starter-generator with the same number of poles operating in the same speed range. This design allows significant weight and volume reductions of the electric machine while its reliability is increased. The present invention may find application in any starter-generator application, including more electric architecture-type aircraft designs currently in development.

摘要： When driven by a variable speed prime mover, a generator system provides relatively constant frequency AC power by independently controlling the main rotor flux rotational speed. The generator system includes an exciter stator that induces current in the exciter rotor windings at a desired frequency and phasing. The exciter rotor windings are electrically connected to and located in a common core as the main rotor windings to provide two-phase excitation current to the main rotor windings. The exciter stator winding is also located in a common core as the main generator stator windings. Excitation is supplied to the exciter stator from an exciter controller, which controls the frequency and phasing of the exciter excitation, based on the rotational speed and rotor position of the generator, to maintain a constant output frequency. The exciter frequency control function of the exciter controller may be eliminated when the generator system is driven by a constant speed prime mover or when a narrow band variable frequency output is required.
