can induction motor becomes as a generator. if yes how it is
possible. if there is a squirrel cage rotor.
Answer Posted / viral sharama
Yes , induction motor can be used as a induction generator.An overexcited induction motor with its rotor running at a speed greater than synchronous speed at negative slip starts generating electricity(a.c).At negetive slip the load resistance R(mech)=(R2/s)*1-s instead of absorbimg power act as a source of power.
This type of generator is not self-staring,the stator requires continous 3-phase supply which is why a 3-phase delta connected capacitor bank is always placed across it inorder to prvide residual mag. flux....
They are used in wind energy production, domestic geerators etc
