(1) Simulate dynamically a separately-excited DC motor with a block diagram modeling in SIMULINK. Use the following parameters: Ra=0.06; La=0.0018; ka=0.1; Bm=0.001; Jm=0.03; Va=1; Tl=0.01; Vd=1; Rd=0.01; Ld=0.01;

Show your block diagram with all connections among blocks as well as plot the input armature voltage, speed, torque and armature current.

(2) Repeat what was asked in the first question with this machine series connected.

(3) Repeat what was asked in the second question with this machine series connected and an AC input voltage instead of DC. Keep an amplitude of the AC voltage equal to 1.

A 230 V, 500 rpm, 100 A separately- excited dc motor has an armature resistance of 0.1 ohms. The motor is driving, under rated conditions, a load whose torque is constant and independent of speed. The speeds below the rated speed are obtained with armature voltage control (with full field) and the speeds above the rated speed are obtained by field control (with rated armature voltage). What motor terminal voltage is needed to run it at 400 rpm? By what...
