A 440 VDC, 60hp, cumulative compound long shunt motor has anarmature resistance of .1 Ohm, a series field resistance of ???Ohms and a shunt field resistance of 80 Ohms. The brush drop is aconstant 2 volts. The stray losses are 2.5 kW. The CEMF at ratedload is 393 volts. Draw the electrical circuit, then determine thefollowing for the above conditions:
A. The armature current:
B. The power developed by the armature:
C. The resistance of the series field:
D. The starting current if motor is directly connected acrossthe 440 line voltage?
E. The value of a starting resistor to limit the initial currentto 150A.
F. The nominal line current when operating at full load?
