Answer Posted / neha a patel
The Induction motor can be stopped immediately by just
interchanging any two of the stator leads. When an
induction motor is rotating at a high speed, during
emergency if situation arises that the motor has to be
stopped immediately, can be done by interchanging any 2
leads of the stator supply. By doing this, it reverses the
direction of the revolving flux, which produces a torque in
the reverse direction, thus causing a breaking effect on
the rotor. This breaking period is called the “Plugging”
period
