Answer Posted / najib
There are different situations in which this question can
be looked into.
Case 1.The motor is lighly loaded
In such a case the motor shall continue to run at the same
speed without any hiccup.
Case 2.The motor is supplying a rated load
In this case the motor shall draw current more than the
rated valeu and run at a slightly less speed
Case 3.The motor is heavily loaded
In this case the motor shall stop running and chances of
burning of winding is very large
Case 4.The motor is stationary
In this situation the motor shall not start at all.
