Answer Posted / ziauddin
if 220v dc supply is given to 1-p fan of 220v then the emf produced is zero n there are no flux ploduced by the magnet n torque wich is used to rotate fan is also zero hence it leads to burning f winding

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 were used. It would make more sense to keep power on the VFD.
