The measurement test for the identification of current - flux linkage characteristics in synchronous reluctance motors

In the paper a new measurement procedure of identification of synchronous reluctance motors parameters is presented. It is based on extension of traditional current decay test, used both in case of induction and synchronous motors [1, 3]. The main aim of the method is to enable to obtain the current-flux linkage characteristic necessary in case of Hamiltonian model of the machine (eq. 1). In case of 3-phase machine without neutral wire, being the most popular in practical applications [3], the method is based on measurement of currents in two independent phases (Fig. 4, eq. 5). The result of its application in a form of trajectories presenting traces of the chosen flux linkage in a current space is shown in Fig. 8b.
