IPM Synchronous Machine Drive Response to Symmetrical and Asynunetrical Short Circuit Faults [PDF]

IEEE Power Engineering Review, 2002
A closed-form solution is presented for the steady-state response of interior permanent magnet (IPM) synchronous machines to symmetrical short circuits including the effects of q-axis magnetic saturation. Machine response to single-phase asymmetrical short circuits is also investigated.
