In an induction motor if air-gap is increased
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 the air gap is increased (a) its speed will reduce. (b) its efficiency will improve. (c) its power factor will reduce. (d) its breakdown torque will reduce. [I.E.S. …

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. diaper number chartWebAir Gap Power in Induction Motor The motor converts electrical energy into the mechanical rotational energy. The input voltage is fed to the stator of an induction motor. The stator … diaper nursery storyWebWhen air gap eccentricity exists in a motor, the air gap flux will be off balance, causing different levels of voltage to be induced onto the rotor. This results in irregular current … citibank posterWebThe speed of an induction motor is always governed by the rotating magnetic field in the stator. This stator field always rotates at a synchronous speed governed by two factors: 1. The number of pairs of poles. 2. The frequency of the applied voltage.
