I. DISCUSSION: Explain the Principles operation of "Self-Excited COMPOUND DC Motor" with regards to the circuit representation and the equation used to provide the graphical analysis.
(A shunt DC motor has a total resistance value for all conditions as Ra= 2 Q and under full load conditions (nominal load) armature current is Ia = 10 A. The nominal terminal Voltage for the motor is Vr-300 V and total value for field circuit resistance for all conditions is Rf=150 Q. Under full load conditions (nominal load), find the internal generated Voltage (EA), excitation circuit current (field current) (If), (total supply current flow, from electrical source) line current (IL), electrical input power (Pin) supplied from the source. Be careful about your solutions to be written readable and write the answers as it was shown below inside boxes.) EA = If = IH (IL) = Pin =
