Difference between VSI (Voltage Source Inverter) and CSI (Current Source Inverter): The difference between VSI (Voltage Source Inverter) and CSI (Current Source Inverter) is given in below table Sl no…
DC Excitation System Working Principle: In dc excitation system, the system has two exciters—the main exciter (a separately excited dc generator providing the field current to the alternator) and a…
Speed Control of AC Commutator Motors: Speed control of ac commutator motors can be had either by varying the applied voltage or by movement of the brushes round the commutator.…
Starting of Electric Drives: The most important processes associated with controlled electric drives are (i) starting, (ii) speed control (iii) braking, (iv) reversal of direction of rotation. All these are…
Repulsion Induction Motor - Construction, Working Principle and Applications: The repulsion induction motor has a single phase stator winding, as a repulsion-start induction motor has, but it has two separate…
Repulsion Motor - Construction, Working Principle and Applications: The characteristics of repulsion motors are similar to those of a series motor, i.e., high startÂing torque and high light-load speed. Its…
Three Phase AC Series Commutator Motor: This machine has a 3-phase stator winding similar to that of an ordinary induction motor and may be wound for high voltage if required.…
