Why squirrel cage rotor slots are usually skewed

Know about the most popular and almost unbreakable construction of Squirrel Cage Induction Motor. Know about the different winding slots, lamination of the stator and its construction. Also appreciate the rugged construction of squirrel cage rotor and know the spectacular reasons for the skewed arrangements of the rotor conductors. Know how a rotating magnetic field is produced. An accurate model of squirrel cage induction machines under ... The air-gap is not considered as being smooth; stator and rotor slots openings effects are introduced in e1 (?, θ). Rotor bars are often uniformly skewed in squirrel cage ...

The problem is that the rotor and stator must have spaces called slots, in the iron for the conductors. The conductors and air in the slots have a ... Squirrel-cage rotor - Wikipedia A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists ...

Skewed Rotor BarsWhy? - PdMA

Skew angle in squirrel cage induction motor. The conductors and air in the slots have a lower reluctance than the reluctance of the iron. There are more slots than there are poles in the stator. The windings are distributed among the slots to form distributed poles. Their is a different numbers of slots used for the stator and rotor. Why are conductors skewed in an induction motor? - Quora
