1.	How are the pulsation losses aggravated?(a) if the air gap is small compared with slot openings(b) if the air gap is reduced(c) if the air gap is increased(d) if the air gap is made larger than the slot openingsThis question was posed to me by my school principal while I was bunking the class.Asked question is from Pulsation Losses & Types of Leakages in division Principles of Magnetic Circuit Design of Design of Electrical Machines
Answer» The CORRECT answer is (a) if the air gap is small COMPARED with slot OPENINGS Easy explanation: The PULSATION losses occurs in the POLE faces and teeth. The pulsation losses are aggravated if the air gap is small compared with slot openings.
