the inductances of PMSM

walid_22046

hello, please, when we calculate the inductances of a synchronous machine with surface magnet, we feed the first phase with a current different from zero and the two other phases equal to zero or half the value of the first phase?
We consider the magnets as air.

Hello Walid;

It is easier to supply Ia = I, and Ib=Ic=0 in order to compute self and mutual inductance. What you indicated we use to use it for static torque computation.
