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 / dinesh lokhande
Basically DC drive consists of Thyristor controlled
rectifier circuit which converts AC to DC and provides
supply to motor armature. As per arrangement of thyristor
circuit DC polarity always remains constant inspite of
change in AC supply phase sequence.
Thus there will not be any change in motor performance.
