A 220V, 1000rpm, 60A separately excited DC motor has an armature resistance of 0.1Ω . It is fed from a single phase full converter with an AC source voltage of 230V, 50Hz. Assuming continuous conduction,
compute:
a) Firing angle for rated motor torque at 600 rpm
b) Firing angle for rated motor torque at (-500) rpm
c) Motor speed for α = 150° and half rated torque
