Zastosowanie metody polowo - obwodowej do obliczania parametrów silników synchronicznych z magnesami trwałymi przy pracy synchronicznej

In the paper one of the methods for calculation of lumped synchronous parameters of PMSM is described. This method, called usually the loading method, was introduced by M. A. Rahman and P. Zhou at the beginning of 90's. The method is based on a finite element analysis of magnetic field inside the machine and simultaneous solving of PMSM equivalent circuit equations for a range of loads. Actually at the Research And Development Centre Of Electric Machines "Komel", the software for analysis and evaluation of PMSM performance at synchronous operation is developed on the basis of described method. This software, as intended, should enable the investigation of PMSM performance for both, current and voltage source supply.
