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.
Note:
My answer may be wrong....
If anybody knows the firm answer can correct me...

I am having a 42KW 3 phase electrical heating furnace, heating element is 80/20 nichrome material, my connections is made in such a way that 2 star connection compromising 2 coils per phase so totally 12 coils, shall if i use it unbalanced star condition (instead of 2 group of 3 phase or 1 group of 3 phase, connecting 4 phases of 5 phases) what will be the consequences and is it acceptable?
ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
