Speed Governor Dead Band and its Effect on AGC: The effect of the Speed Governor Dead Band is that for a given position of the governor control valves, an increase/decrease…
Two phase AC Servo Motor: For a low-power (a few hundred watts) control application, a balanced Two phase AC Servo Motor is ideally suited as it can be driven by…
Dynamic Modelling of Induction Motor: In general, the mechanical time-constant for any machine is much larger than the electrical time constant. Therefore, the Dynamic Modelling of Induction Motor can be…
Air Gap Power in Induction Motor | Torque and Power Output Equation: Air Gap Power in Induction Motor - The circuit model is shown in Fig. 9.10. The power crossing…
Induction Motor Equivalent Circuit: Induction Motor Equivalent Circuit - The behavior of the induction machine was studied in terms of the basic field phenomenon. The attempt here was purposely focused…
Determination of the Synchronous Reactance | Open Circuit and Short Circuit test of Synchronous Machine: Determination of the Synchronous Reactance - With the assumption of a linear magnetic circuit, the…
Braking of DC Motors: Controlled slowing or stopping of a motor and its driven load is as important as starting in many applications (e.g. cranes, traction on a slope to…
DC Motor Losses and Efficiency: The Losses and Efficiency of a transformer have been studied in earlier lesson. As in the case of transformers, it is more accurate to determine…
