Experiment 6 Shunt Excited Dc Motor Practical Summary Data Pdf The document outlines a practical experiment for reversing the direction of a dc shunt motor, detailing the necessary apparatus, specifications, and theoretical background. This video describes about conduction experiment to plot the performance characteristics of dc shunt motor.
Experiment No 2 Shunt Series And Compound Mach Ac Dc Pdf From this diagram you can see that the speed of the shunt motor stays fairly constant throughout its load range and drops slightly when it is drawing the largest current. Explore dc motor characteristics (shunt, series, compounded) with this lab manual. torque, speed, efficiency experiments for power engineering students. Discuss the observation made in part 1.1 and explain how speed above normal and below normal are obtained for a shunt motor driven from a constant dc voltage source. Take measurements of motor speed (in rpm), motor terminal voltage, motor line current and the dynamometer scale reading (in lbs) and record in the data sheet as the generator load is varied.
Experiment No 7 To Connect Start And Reverse Direction Of Im And Dc Discuss the observation made in part 1.1 and explain how speed above normal and below normal are obtained for a shunt motor driven from a constant dc voltage source. Take measurements of motor speed (in rpm), motor terminal voltage, motor line current and the dynamometer scale reading (in lbs) and record in the data sheet as the generator load is varied. Shunt motor: the direction of rotation of a dc shunt motor can be reversed by changing the polarity of either the armature coil or the field coil. in this application the armature coil is usually changed, as was the case with the series motor. The document describes an experiment on a dc shunt motor. the objectives are to understand dc motor operation, parameters for measuring performance, and applications of shunt motors. Explore dc motor construction, wiring, and performance with this lab experiment. analyze shunt and series motor characteristics. ee 448. Table: result: thus, the load test on dc shunt motor is conducted by ltspice simulation and its performance characteristics are drawn. inference: at lower back emf the efficiency is more and for higher back emf efficiency is lower. the field current is constant for a given supply voltage whereas the line current is directly proportional to.
