Standstill Self-Commissioning Procedure for Synchronous Reluctance Motors based on Coenergy Model

This paper describes a fast and effective procedure to estimate the whole magnetic map of a synchronous reluctance motor at standstill. Flux linkage curves are approximated by using a coenergy-based model which only requires the knowledge of magnetic maps borders. To measure the necessary flux linkage curves, the proposed procedure is tailored for the chosen model, with the aims of minimising any rotor movements and keeping the computational effort at bay. The proposed procedure is composed by two consecutive tests and it is suitable for the self-commissioning of electric drives. Experimental results on a 3 kW synchronous reluctance machine are reported.
