Induction motor always operates at lagging power factor
because induction motor is a electrical machine in which
only stator is supplied and rotor gets its power through
mutual induction.In the rotor how much current lag behind
the voltage is actually depends on the material used for
rotor.

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.
