(a) A $200 \mathrm{~V}, 1500 \mathrm{rpm}, 10 \mathrm{~A}$ separately excited DC motor has an armature resistance of 1 ohm . It is fed from a single phase full converter with an AC voltage source of $230 \mathrm{~V}, 50 \mathrm{~Hz}$. Armature current is continuous. Calculate
Explanation
The motor speed at the firing angle of $45^{\circ}$ can be calculated using the equation for developed torque. By rearranging the equation to solve for motor speed, we can determine the motor speed at the given firing angle and torque.
