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.
In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
Gravitational field can also be shown by lines of force. This is same in several ways as that of electric lines of forces. With one dissimilarity, electric charges are negative and
