“…This is because a capacitor embedded in the DC power supply will cause oscillation of the measured current. This effect is evident from the results presented in [8], where clear oscillations may be observed. In [7], a lead acid battery was used as the DC power supply.…”

-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.

“…A third problem with the DC method is that it requires extra power electronics circuits to help switch on or switch off the DC power supply [8]~ [11]. For different test motors with different power ratings, the power electronics circuits may need to be modified.…”

“…The flux linkage characteristic is usually obtained across the range of rotor positions and operating current values, and this information can then be used to facilitate advanced control techniques [20][21][22]. This approach is based on single-phase excitation, and can be accurate under multiphase excitation in situations where mutual inductance effects can be ignored.…”

“…It is not easy to measure the exact inductance parameters of a SynRM while considering the saturation effect. Several methods that measure or calculate the electrical parameters of a motor have already been proposed in [10], [11]. These methods simply measure the phase inductances but they need an external circuit.…”

“…These methods simply measure the phase inductances but they need an external circuit. Moreover, they need to know the position information [10] or have to calculate a complex flux polynomial to obtain the synchronous inductances [11]. The researchers in [12] measured the SynRM synchronous inductances considering the iron loss from a single phase test.…”

This paper proposes an estimation algorithm for the electrical parameters of synchronous reluctance motors (SynRMs) by using a synchronous PI current regulator at standstill. In reality, the electrical parameters are only measured or estimated in limited conditions without fully considering the effects of the switching devices, connecting wires, and magnetic saturation. As a result, the acquired electrical parameters are different from the real parameters of the motor drive system. In this paper, the effects of switching devices, connecting wires, and the magnetic saturation are considered by simultaneously using the short pulse and closed loop equations of resistance and synchronous inductances. Therefore, the proposed algorithm can be easily and safely implemented with a reduced measuring time. In addition, it does not need any external or additional measurement equipment, information on the motor's dimensions, and material characteristics as in the case of FEM. Several experimental results verify the effectiveness of the proposed algorithm.
