Hello, so for this question I know how to solve it but I still have a few questions. First when the question means it's rated at 20 HP and 600 V, it's referring to the source voltage and Pin correct? Also in order to solve this question, the rotation loss Prot was neglected. This was because at No load condition the armature current was zero meaning that we were assuming a ideal DC motot hence Prot = 0 correct?
