Question
In the simple, one loop, one turn, 2-pole, DC machine: R = 0.5 Ohms, VB = 180 V, r = 0.45 m, B = 0.4 T, and the length of the conductor L = 0.9 m. The machine was rotating at no-load steady-state speed when a torque of 16.2 N.m is being applied to the shaft in the opposite direction of rotation. Find the current i and the new steady state speed of the loop. Select one: a. i = 40 A , Speed = 390.625 rad/sec b. i = 0 A , Speed = 555.6 rad/sec c. i = 50 A , Speed = 478.4 rad/sec d. None
