7. In squirrel cage induction motors, the rotor slots are usually given slight skew in order to a) reduce windage losses b) reduce eddy currents c) reduce accumulation of dirt and dust d) reduce magnetic hum. 8.
The number of turns and size of wire are limited by the core dimensions. However, in the squirrel cage rotor, there are many more variables in the design. One of the variables is the shape of the rotor slot. Many rotor designs are skewed. So, why are rotors skewed? Skewed Rotor BarsWhy? - PdMA Skewed Rotor Bars...Why? If you take a good look at your squirrel cage induction rotor you might see that the rotor bars are not truly parallel with the shaft and that they actually have a skewed look as if someone grabbed both sites of the rotor and twis ted in opposite directions. Fol-lowing are four reasons why the motor designers may have ... Construction of squirrel cage induction motor explained 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.
