dc.description.abstract The accurate identification of flux linkages and inductances play a vital role in developing high-performance control methods for synchronous motors (SMs). In this thesis, the identification of flux maps of SMs at constant speed is done. The aim of this thesis is to achieve look-up tables of flux linkages as a function of machine currents. Simulation are performed on a 6.7-kW synchronous reluctance motor (SyRM). The current controlled SyRM, operating at constant speed, is fed with current sequences and the corresponding voltages are calculated. By using these calculated voltages, the motor flux linkages are identified and stored in the form of look-up tables. The iron losses and stator resistance variation are compensated during the identification process. Theses linkage look-up tables can be used as a benchmark for testing different saturation models of synchronous motors. From these look-up tables, the information about motor inductances can be obtained which can be used to fully exploit the motor torque and speed range by determining various control strategies such as the maximum torque per ampere (MTPA) and maximum torque per volt (MTPV). en
