摘要：A position sensing apparatus () derives rotor position of a synchronous machine() from signals output from the machine (). In one embodiment, the position sensing

apparatus () comprises: a bandpass filter () that filters phase voltage signals output frommain stator windings () of the synchronous machine () during AC excitation, therebyextracting a rotor position-indicating component from the phase voltage signals; aconverter () that converts the filtered phase voltages into balanced two-phase

quadrature signals, the balanced two-phase quadrature signals indicating positioning ofthe rotor (); and an excitation controller () for controlling AC excitation frequency as afunction of rotor speed.
