Title: Obtaining the Current-Flux Relations of the Saturated PMSM by Signal Injection,
Abstract: This paper proposes a method based on signal injection to obtain the
saturated current-flux relations of a PMSM from locked-rotor experiments. With
respect to the classical method based on time integration, it has the main
advantage of being completely independent of the stator resistance; moreover,
it is less sensitive to voltage biases due to the power inverter, as the
injected signal may be fairly large.
