Answer / sreenu

Because IM rotor is short circuited with copper bars, which
can carry more current rating than stator windings.

Answer / vasudeva rao

because in induction motor stator only carrys the supply
current but not a rotor. rotoronly carries the mechanical
load. that is why if any fault occurs in supply system
stator winding gets damaged not rotor

i heard that power factor(PF) is the main concern for industries, if they are maintaining PF around 0.6 they will be fined for that. now the question is, how can they improve the PF ranging between 0.9 to 0.95 which is safe for them i,e escaping from the fine?
