ill) Based on the mathematical expression regarding the electrical and mechanical equations in (1), determine the armature voltage and armature current of a 10 HP, 200 V, 2000 rpm separately excited DC motor that controls a load requiring a torque of Tz = 45 Nm at a speed of 1200 rpm. The field crcuit resistance is Rs = 1472, the armature circuit resistance, R, = 0.25 2 and a back emf constant of the motor is Ky = = -2- SULIT SULIT (BEKE 4753) 0.7032 V/(A rad's) and has a similar value with the torque constant. The field voltage is 220 V. (Assumption: The viscous friction and no-load losses are negligible. The armature current may be assumed continuous and ripple free.)
