(c) A 50 HP, 250 V, 1200 r/min, DC shunt motor has an armature resistance of 0.06 2. Its field circuit has a total resistance (Radj + RF) of 50 2, which produces a no-load speed of 1200 rpm. (i) Sketch an equivalent circuit of the motor. (ii) Deploying the understanding of a DC shunt motor, demonstrate the derivation steps of the formula for output speed, wn versus induced torque, tind of the motor. (iii) Calculate the motor speeds when the input current at 100 A, 200 A, and 300 A. (iv) Using the results obtained from Q3(c)(ii, plot the torque-speed curve of the motor.

Question B1 [15 pts] An universal motor is very similar to a DC series motor in construction, but it is modified slightly to allow the motor to operate properly on AC power. A washing machine is driven by an universal motor, which is powered by single-phase AC source having 110 Vac and 60 Hz. The armature winding of the motor has the resistance and inductance of 0.4 Q2 and 3 mH, respectively. The field winding of the motor has the resistance and inductance of 0.8 02 and 6 mH, respectively. When the washing machine operates at half load torque, the motor draws 10 Aac and runs at 1000 rpm. Calculate the input current and speed of the motor when the washing machine operates at full load torque. At half load torque, (i) Calculate impedance of the armature and field windings. [3 pts] (ii) Calculate the average electromotive force (emf) and average current in the armature. [4 pts] At full load torque. (iii) Determine…
