A triplex lap wound armature has 300 turns and takes 125 A of armature current. The flux per pole is 20 mWb and the 2-pole series DC motor has a rated speed of 480 rpm with rotational losses of 700 W. Solve for back emf (V)
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.
