Case 1: over excited; 1/s; typical power factor correction: shunt cap.
Case 2: excitation twicked to 0 pf; equivelent shunt R
Case 3: underexcited; s; shunt inductance.
But, in all three cases will produce the extra-amps for locked-rotor motor startings.
The basic 1/s, pole at zero, 20dB per decade is not that exciting as a filter, But there must be more to it than that.
We have a case of 400Hz contractor supplied equipment tripping at a turn of the head. As a replacement, maybe the shunt connected motor would stabilize the power, to allow the anal retintive equipment to function.
