what is the generator rating for 40 amp load of 3phase motor.??
400v voltage of generator...
plz tell me with formula its urgent...plzzz...
and also tell me that this 40 amp at all phases mean 40 amp
on red,40 amp on yellow,40 amp on blue......
or the total sum of that 3phase is 40 amp....

P=root3*VI cos¡è.
this is the formulae for your question?
where
root3=1.732
V =APPLIED VOLTAGE
I =FULL LOAD OF THE
MOTOR
cos¡è=0.85
P= rating of generator

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
