  • Position sensor emulator for a synchronous motor/generator
    Publication number: 20040052217
    Abstract: A position sensor emulator system and method for use in the control of synchronous machines are disclosed. The position sensor emulator system (220) includes a first bandpass filter (222) that filters phase voltage signals from a stator of a synchronous machine (230). A converter (224) that converts the filtered phase voltages into balanced two-phase quadrature signals. A rectifier (226) that rectifies exciter voltage signals of the synchronous machine (230) and a second bandpass filter (228) that filters the rectified exciter voltage signals to generate a reference signal.

  • Gas turbine engine starter generator with multiple windings on each exciter stator pole
    Publication number: 20040027078
    Abstract: A rotating electrical machine, such as an aircraft starter-generator, includes an exciter that has its stator windings divided into a number of sections. A plurality of switches are electrically coupled to the exciter stator winding sections and are configured and controlled so that the exciter stator winding sections may be selectively coupled in series or in parallel with one another, and selectively coupled to receive either DC or AC power.
