If the frequency of 3-phase supply to the stator of 3-phase induction motor is increased, then synchronous speed is ________? Why ?





Ans:------ Increased
Explanation:   As we know that;   f = NSP/ 120
It is clear that f NS i.e., frequency (f) is directly proportional to the Synchronous speed (NS).
In more clear words, when frequency increases, Speed also increases.
