In case of Alternator, It rotates from 0 degrees to 180
degrees and then from 180 degrees to 360 degrees. In doing
so it cuts the flux lines do to which an emf is produced in
an alternating manner.

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.
