Solved Experiment D C Shunt Motor Make Conclusion Chegg Make conclusion & recommendations in this experiment. at least two paragraph. no need to draw illustrations. here’s the best way to solve it. answer: we observe from the experiment that when motor is loaded iara drop increases which makes speed a little less than the no load speed. The procedure involves connecting a dc motor, power supply and dynamometer. speed and current readings are taken at different torque levels with constant voltage to generate a speed torque curve. calculations are done to determine speed regulation and starting current.
Solved Experiment D C Shunt Motor Make Conclusion Chegg The resistance of the shunt field circuit is 240 ohms, and the total armature circuit resistance is 0 ohm. the motor has a commutating winding, and armature reaction is neglected. Solved examples of dc shunt motor problems covering speed control, armature resistance, and field resistance adjustments. In electrical motors, series circuits, and equal circuits are ordinarily known as series and shunt. hence, in dc motors, the associations of the field windings, as well as the armature, should be possibly equal, which is known as dc shunt motors. In this lecture, some typical problems on d.c machines are worked out not only to solve the problems but also to bring out important features of the motors involving its performance. to begin with, few problems on d.c motors have been solved and then problems on the generator are taken up.

The experiment confirmed that in dc shunt motors, torque is directly proportional to armature current due to the near constant field flux, resulting in a linear t i characteristic. Solved problems on dc motor speed control by field weakening, armature resistance insertion, and flux variation methods. As the turns are made up of thin wire, the shunt winding is quite small in size. unlike heavier gauges of wire in the winding in series motors, the shunt winding in this motor cannot carry very high current. As the magnetic field strength saturates, increasing the field current may not result in a proportional increase in motor speed. the motor may reach a point where further increase in field current has little effect on the speed, leading to a non linear relationship between if and n.
