In the I.M. rotor consists of uninsulated copper or aluminium bars called rotor conductors. The bars are placed in the slots. The bars are permanently shorted at each end with the help of conducting copper ring called end ring. These bars are usually brazed to the end ring to provide good mechanical strength.
