WE know that for Inductor X=2pifL,In DC f=0,then X=0
so,V=IX=0;But In the DC excitation of rotor of AC
generator,DC motor field coil which coils are inductor so
why does not applying DC voltage short the rotor coil of AC
generator and field coil of motor?If it would then DC source
might be damaged but it is not happened.

Is a contactor (or master relay) required between incoming
lines and a VFD? The question goes to safety. If a
contactor were used before the VFD and an e-stop engaged
then the motor will coast to a stop (i.e. VFD loses power)
instead of stopping much faster if the VFD braking fucntion
It would make more sense to keep power on the VFD.
