A 220V, 1500rpm, 10A separately excited DC motor has an armature resistance of 1 Ω . It is fed from a single phase fully controlled bridge rectifier with an AC source voltage of 230V, 50Hz. Assuming continuous load current, compute
a) Motor speed at firing angle of 30° and torque of 5NM.
b) Developed torque at firing angle of 45° and speed of 1000rpm.
