Parameter determination of synchrnous machine with radial permanent magnets using analytical calculation and standstill tests

In this paper, the two methods used and compared for obtaining the values of direct axis and quadrature synchronous reactance, as well as leakage reactance of the permanent magnet synchronous motor with radial magnets (RPMSM) are: analytical calculation of parameters, and the standstill tests, with locked rotor. The rotor of the motor studied in this paper contains embedded symmetrical sections of aluminum molded squirrel cage. The stator phase winding consists of two sets of turns that can be connected either, in parallel or series, providing a dual voltage connection of the PMSM across three-phase 230V or 460V. The two methods described in this paper showed good correlation of results. These resulting values are required as inputs for the specification of the controller parameters of AC drives using RPMSM.
