Q6. A 50 Hp 250V, 1200 R/Min DC shunt motor with
compensating winding has an armature resistance (including the
brushes, compensating winding and inter poles) of 0.06 ohms. If
the field resistance Radi + R, is 50 ohm which produces no load
speed of 1200r/min. there are 1200 turn per pole on the shunt
field winding.
