Why are the slots on the rotor of an induction motor skewed ... In Squirrel cage rotor, slots in lamination or rotor core is not made parallel to the rotor shaft. A slight angle is maintained due to some advantages. This is called the rotor Skew. Rotor of an Induction Motor skewed due to following reason… Squirrel-cage rotor - Wikipedia A synchronous motor may have a squirrel-cage winding embedded in its rotor, used to increase the motor starting torque and so decrease the time to accelerate to synchronous speed. The squirrel cage winding of a synchronous machine will generally be smaller than for an induction machine of similar rating. How does the skewed rotor in a squirrel cage induction motor ... How does the skewed rotor in a squirrel cage induction motor help to produce a smooth torque curve for different position of rotor?. Electric motor basics: Why are rotors skewed? | EASA
In Squirrel cage rotor, slots in lamination or rotor core is not made parallel to the rotor shaft. A slight angle is maintained due to some advantages.
