Metal Arc Welding Working Principle: In this type of metal arc welding, a metal rod of the same metal as being welded forms one of the electrode and also serves as a filler and no…
Sensors Based Computer Data Systems: This Sensors Based Computer Data Systems describes hardware/software which is commercially available at several levels of completeness, ranging from single board computer "front ends" to stand alone system and high…
What are Passive Filters?: Passive filters are mainly networks using inductors, capacitors and resistors. The classical theory employed was based on the image parameter theory which in turn was based on the filter's characteristics and…
Two Reaction Model of Salient Pole Synchronous Machine: In a Two Reaction Model of Salient Pole Synchronous Machine, the flux established by a mmf wave is independent of the spatial position of the wave axis…
Rotating Electrical Machines: We Know that electromechanical energy conversion takes place whenever a change in flux is associated with mechanical motion. Speed voltage is generated in a coil when there is relative movement between the…
