Detailed Solution
Download Solution PDFConcept of Slip in Induction Motors:
Slip (s) in an induction motor is defined as the difference between the synchronous speed (Ns) and the rotor speed (Nr), expressed as a fraction of the synchronous speed:
s = (Ns - Nr) / Ns
Where,
- Ns = Synchronous Speed
- Nr = Rotor Speed
Given Data:
- Slip (s) = 1
Analysis:
When slip (s) is 1, the equation becomes:
1 = (Ns - Nr) / Ns
Multiplying both sides by Ns, we get:
Ns = Ns - Nr
Rearranging, we find:
Nr = 0
Conclusion:
Hence, slip is 1 when the rotor is stationary.
