Question

1. Determine the torque vs. speed and torque vs. current characteristics for a separately- excited dc motor with the following parameters: 2.3 hp, 220 V, 6000 rpm, R_a = 1.39?, L_a = 0.00182 H, K_b = 0.331 volt/rad/sec. The machine has rated field excitation and its armature is fed a constant voltage of 220 V dc.
