220 V, 1200 rpm, 16 A separately excited motor is controlled by a l-phase fully
controlled rectifier with an AC source voltage of 230 V, 50 Hz. Enough filter inductance
is added to ensure continuous conduction for any torque greater than 50 percent of rated
torque, Ra. = 4 Ω and have La= 30 mH. Calculate motor torques for the firing angle
α=120° and speed =-800 rpm
