Why the starting current in Induction Motor is very high as
compared to normal rated current ????
Answer Posted / avd
Dear, Back EMF is not present during starting (till rotor
achieves its speed) Hence starting curent will be high. You
can consider motor as a secondary shorted transformer
during starting. Hope it is clear now...
