Measurement and instrumentation of a switched reluctance motor

The authors describe and compare various techniques for the measurement of switched reluctance motor (SRM) inductance for any rotor position and level of excitation. Results for an experimental prototype are compared to the analytical and finite-element analysis predictions. It is shown that the proposed flux linkage method is the most appropriate for the SRM and can be applied to the direct measurement of the coenergy change for the steady-state operation of the motor.<
