QA.2 a) b) c) d) A 480 V permanent-magnet excited DC motor has armature resistance of 1.5 . When driving a load of constant load torque at rated speed of 1200 rpm, the armature takes rated 20 A. Speed is controlled by armature voltage variation, and armature is supplied from a three-phase fully controllable bridge rectifier. Available AC voltage is three-phase 415 V, 50 Hz, interfacing transformer is not used, and armature current is continuous. The machine operates at rated speed with rated load. Determine rectifier output voltage and thyristor firing angle. Determine the rated motor torque and power. The machine operates at 25% of the rated speed with 75% of the rated load. Determine rectifier output voltage and the thyristor firing angle. A three-phase rectifier can operate with different load types at the output. One possibility is placement of a capacitor across the output. Explain when this is done and why?

A freewheeling DC motor is driven with 1000 rpm and a nominal load torque of 80Nm. The field circuit resistance is 200 and the armature circuit resistance is 0.2 O. The field coils are fed with a zero degree transmission angle through a single-phase fully controlled converter connected to a single-phase 240V source. The armature circuit is fed from a single phase 400V source through another fully controlled converter. Magnetic saturation has been neglected, the motor constant is given as 0.8 V - s / A - rad. Assuming that there is no fluctuation in armature and field current, find the control angle of the converter feeding the armature at nominal load.
