A 250 volt dc motor taken an armature current of 28A when running at 1000rpm the armature resistance is 0.25Ω. Determine the no load speed if the armature current is 4A at no load
I need some help on this question When the armature current is at 0A I can solve the problem im not quite sure what to do when the no load speed of the armature current is 4A
So far I have
EC=250V-28Ax.25Ω=243V
Kg=243V/1000rpm=.243
not sure what to do next
help on the next step would be much appreciated
