Answer Posted / karthik
a 3 phase machine is used for high power application and the rotating magnetic field is created by the 3 phases hence when it is connected to a single phase supply we will not be able to create a rotating magnetic field unless the field is connected along with a capacitor or inductor to create a phase difference. but whena single phase machine is connected because of the inherent phase lag between the various phase of supply.

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.
