Abstract
Knowledge of actual flux linkage versus current profiles plays an important role in design verification and performance prediction for switched reluctance motors (SRM's) and permanent magnet motors (PMM's). Various measurement methods have been proposed and discussed so far but each method has its own limitations and constraints. In this paper, first an investigation and comparison of existing measurement methods is reported. Next, a simple pure AC flux linkage measurement method is discussed and evaluated, which does not require a search coil. Experimental results are given, obtained using the described AC method on an SRM and on a PM motor. For these two motors, the measured flux-linkage-current curves are compared to those measured using other methods. The comparison results show good effectiveness of the proposed AC method for both the SRM and the PM motor.
