A 100 hp, 1750 rpm, d.c. shunt motor has an armature inductance of 1.15 mH, a resistance of 0.0155 2 and an armature voltage constant of 1.3V.s/rad. The motor is operated from a three-phase half-wave controlled-rectifier at rated armature current of 35 A. Find the firing angle a, assuming that the supply voltage is 400 V and the motor speed is 1750 rpm. Consider the thyristors to have a forward voltage drop of 1.5 Volt and assume continuous conduction.

A 200V, 875rpm, 150 A separately excited dc motor has an armature resistance of 0.06Ω. It is fed from a single phase fully controlled rectifier with an ac source voltage of 220V, 50Hz. Assuming continuous conduction. Determine motor speed for α = 160o and half rated torque.
