Hi all,
Do Slip ring Synchronous motors contribute to short circuit level of a power system as do induction motors?
Thanks.

RE: Synchronous Motors
Synchronous motors absolutely do contribute to the available fault - just like a generator would (electrically a synchronous motor & a synchronous generator are virtually identical).
The fault contribution of a synchronous motor would be a function of the subtransient reactance (Xd")- typically 17 -25% in most synchronous machines 600RPM+. See IEEE std 141 for more info.
