Explain Squirrel- cage rotor
Squirrel- cage rotor having of a slotted laminated core of sheet-steel. The slots of the rotor are not always parallel to the slots on the stator, but they are given a twist called as skew. (Skew decreases noise, eliminates cogging and enhances the starting torque). The windings are placed in the slots. Every slot carries a thick copper or aluminum bar. These bars are short-circuited on either end by a solid copper or aluminum ring known as end-ring. Most of the 3-phase induction motors are of squirrel cage type, due to its rotor is simple and rugged in construction and is cheaper.
What are the basic reasons for loss of residual magnetism? How do you get it? What is the requireable and maximum DC voltage is to be applied to get back the residual magnetism?
so we just started physics in grade 10, and i dont understand to much of it.. could you help me better understand it? and help me understand what i should expect?
