New Design in order to Reduce Rotor Reaction for Squirrel Cage Induction Motor: Skewed Slits

In this study, a new design has been developed to reduce the rotor reaction generated in squirrel cage induction motors. In this new design, slits have been opened between the slots of the stator and rotor, and the resulting change in the rotor reaction angle between these slits and the stator and r...
