Answer Posted / gajanan
in rotor resistance starter external resistance made
connect across rotor winding to reduce rotor current which
consequently reduce starting current.
in case of sq. cage motor there are rotor conductors short
circuited permenantly at end rings and ext resistance can't
connect across it.

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
