Hi, I need help with a question. Any help would be appreciated.
A dc shunt motor runs at 1200 rev/min from a 200 V supply when taking an armature current of 20 A. Calculate the speed at which it will run from a 150 V supply when taking an armature current of 18 A. The resistance of the armature circuit is 0.8 Ω. Assume the flux at 150 V to have decreased to 75% of its value at 200 V
Regards
Jonty
