3、ronous motors( PMSM). Fluctuating highfrequency signal injection method was used to realize the sensorless PMSM vector control. When fluctuatinghigh frequency voltage signals are injected into the stator coils of PMSM, the corresponding high frequencycurrent response with rotor position information
4、are measured using the saliency of PMSM and rotor positioncan be extracted. Experimental results show the feasibility and validity of this method.Keywords:permanent magnet synchronous motor( PMSM) ;fluctuating high frequency voltage signal; sal-iency; sensorlessnull nullTe: (1977- ), o,p V 3, =,Emai
