摘      要：The electrical-magnetic characteristics of a Switched Reluctance Motor(SRM)exhibit highly nonlinear relationshipwith respect to the rotor position and excitation current,which poses challenges for both precise static measurements and exact calculation of these properties in real-time *** guarantee that an in-lab test result can be used in the application,firstly a measurementmethod is proposed to characterize the SRM s electromagnetic properties such as the flux linkage,magnetic co-energy,phase inductance and electromagnetic torque on the basis of an installed SRM control circuitry and half-bridge power *** this means the characterization process is equivalent to the online observation in its ***,a theoreticalmodel is built to discriminate the physical meaning between the incremental inductance and the phase inductance,which is the origin of other relevant *** helps to guide the correct utilization of the characterization *** an in-situ cross-validation experimentation according to the magnetizing and demagnetizing status measurement verifies the feasibilities and accuracy of the proposed inductance measuring method,which avoid a dubious FEM-based comparison between the numerical calculation and experimental ***-validation experiment shows that the proposed in-situ characterization scheme obtains an accurate full-range electromagnetic *** proposed methodology breaks the barrier between the in-lab measurement and on-line utilization of the SRM parameters,highlighting the merits that it completely includes the in-situ factors and replicates the operational scenario without the need of specifically designed instrumentation,which is especially suitable for rapid field characterization for high power motors.
