Set the megger to Ohms and then check the leads … WebThe armature circuit resistance can then be calculated by using the following basic steady state DC motor equation: E = I x R + (Ke x w), where. E = applied voltage. I = current. R = armature circuit resistance. Ke = voltage constant. w = speed (omega) Since speed = 0 with the armature locked in place, the back emf voltage (Ke x w) = 0 and the ...
