Dear Researchers, can you briefly explain how to obtain the magentic flux linkage if the back-emf constant is known? Can you suggest any useful links on this topic? My motor under the test is surface mounted PMSM (SPMSM). Thanks for advance!
PMSM is synchronous motor with permanent magnet hence the flux linking could be considered almost constant, compared to field excite, cannot be over or under excite or would run at almost constant power factor. Back E.M.F would be momentarily during variation of load and would provide the needed damping. Could be obtained by the E.M.F equation Eb=KO=O(ZNP/60A), O the flux linking.
Dear Bhupendra, thank you for the answer. In the equation above:
Eb - back emf;
K = ZNP/60A;
ZNP - number of pole pairs;
60A - it is 60 Amps.
Is my understanding correct?
Windings perimeters are depending on winding types, Z the conductor, P the poles developed, A the parallel paths….
