When electrical energy is converted to mechanical energy m/c acts as a motor& when mechanical energy is converted to electrical energy it acts as a generator. This is the basic principle. As far as induction motor is concerned what mentioned above is true.

Answer / shahbaz sahikh

when yhe slip is possitive at that time machine acts as
motor as s=(Ns-N)/Ns and when slip is negative acts as
genrator.

why battery dc voltage become Half when we check with respect to ground for example 120volts + and - terminals and when we check + terminal with Earth thats 60volts why 60volts same result on 24Volts and with ground 12Volts only expert answer that thanks we can not ground the battery.

i am using auto transformer for starting of induction motor to provide reduse voltages...but the principle of a tansformer according to definition"which transform energy to on circuit to another circuit with constant power and constant frequency". so if i am using reduse voltage then current obsely hige because power is same.but we use auto transfarmer for starting of induction motor to give low current.but here according to definition we are giving hige current.
