3. Why integral wind-up is harmful in a closed-loop system? Explain.
Consider a induction motor (slip-ring) having a three-phase star-connected rotor. When the stator is supplied with rated voltage, slip ring being open circuit, the induced emf value is 65 Volts. The value of 0.6 ohm and 5.5 ohm are the resistance and stand still reactance of rotor per phase. Determine the following: 1. Rotor current per phase when the rotor is at stand still and connected to rheostat of 5.5 ohm (star-connected) and reactance 0.6 ohm per phase. 2. Rotor current per phase when motor is running at slip of 4% while rheostat is short circuited.

Question 12 The following sequential statements, when completed, describe armature reaction in a DC generator. Complete each statement by inserting the appropriate word from among those provided in the word list below. Word list:armature, between, brushes, clockwise, commutator, currents, direction, distortion, increase, induces, inline, interpoles, main-field, neutral-plane, power, rotating, rotation, slip-rings, slow-down, sparking, speed, torque, voltage. Armature reaction is the __________________ of the air gap flux that results from the interaction of the magnetic field created by _________________ in the armature conductors with uniform magnetic field of the __________________ winding. Armature reaction results in pole tip saturation and a shift in the ________________, which lies ________________ the main field poles at no-load.

The results are as follows: When operated as a synchronous motor on load the power input to the motor is 55.8KW and the armature line current is 70A. The excitation of 38.6A at 250V dc gives the normal open-circuit voltage. DC resistance test: dc line voltage 17.5V and dc line current 70A.
