Question
A three-phase, , -pole induction motor runs at no-load with a slip of . With full load, the slip increases to . The speed regulation of the motor (rounded off to decimal places) is ________.
Correct answer
4.1 to 4.4
Solution
1.Calculate Synchronous Speed ():
2.Calculate No-load Speed ():
Given no-load slip 3.Calculate Full-load Speed ():
Given full-load slip 4.Calculate Speed Regulation:
Rounding to 2 decimal places, we get .Continue learning with Success Tracker
