Fast Experimental Magnetic Model Identification for Synchronous Reluctance Motor Drives

The accurate magnetic model is mandatory for high-performance control of high anisotropy synchronous machines. This paper presents a time-efficient and identification based on triangle current injection while the machine under test driven at constant speed by prime mover. pattern allows scanning whole range current, reducing time compared to standard constant-speed method (CSM) with same level accuracy. ohmic voltage drop inverter nonlinearities are compensated using average motor generator modes. reluctance used as case study validation through comparison between experimental results obtained proposed CSM against finite element simulation. Moreover, temperature variation winding measured showing no considerable changes during test.
