A shunt DC motor is fed from a 224 V DC source. The field coil has a resistance of 124 ?. The total armature resistance (including the contact resistance of the brushes against the segments of the commutator) is 0.14 ?. The field adjusting resistor is set at 225 ?. The motor is rated for 25 hp. The total rotational losses have been measured at full load as 1400 W. The motor has compensation windings. You load this motor to its full capacity. What is the full load speed, in rpm? RPM(f) What is the full load terminal current, in amps? A(g) What is the speed regulation between idling and full load in percent? %(p) What is the torque at the mechanical load, in N.m
