Question
When induction motor is at standstill, slip of the machine will be:Question 5Select one:a.0b.1c.Infinited.-1
Solution
The slip of an induction motor is given by the formula:
Slip, S = (Ns - N) / Ns
where, Ns = Synchronous speed N = Actual speed of the rotor
At standstill, the actual speed of the rotor (N) is 0. Therefore, the slip (S) at standstill is:
S = (Ns - 0) / Ns S = Ns / Ns S = 1
So, the correct answer is b. 1.
