Webinduction motors depends upon the shape of the slots (i) Open slots: In this type of slots the slot opening will be equal to that of the width of the slots. In such type of slots, assembly and repair of winding are easy. However such slots will lead to higher air gap contraction factor and hence poor power factor. Webin an induction motor if airgap is increases then power factor of the motor gets decreases because the motor draws more magnetizing current which lags the voltage by a more …
WebDec 18, 2015 · 148. In induction motors, where the air-gap is usually quite small, it is necessary to correct the air-gap. permeance for the effect of slot openings. These make the permeance of the air-gap slightly smaller. than calculated from the physical gap, effectively making the gap a bit bigger. The ratio of effective.
WebIf the air gap is increased, it will offer high resistance to magnetic flux and the stator will draw more magnetizing current from the supply to maintain the required flux in the air gap to the rotor. This will reduce the power factor of an induction motor or …
WebMay 14, 2024 · I have been trying for a while to summarize the effects of increasing air gap in an induction motor with constant load. I understand that increasing air gap with constant supply voltage demands high magnetezing current for the same magnetic flux, and this also causes reduction in power factor. cynthia kuhn books in orderWebIn an induction motor if air-gap is increased.
