A dc motor running on dc drive whose input is 3ph AC what
will happen if we change the phase sequence of dc drive for
e.g (R Y B) is connect as R B Y, will the motor run as same
as previously running before changing phase without any effect

Answer Posted / anil bhatia
this answer is for Mr Arun Kokje . you can ask equation in proper place not in answer side .find the initial current and time to reach this motor to run in running in full speed current. the initial impedance of this motor is very low (300HP), it is just create like near to sort circuit current for 1250 KVA DG.
soft starter will solve your problem .
