The power flow from input to output is known as power stages or power flow diagram. Efficiency : It may be defined as the ratio of output in watt (or KW) to the input in watt (or KW). Mechanical efficiency, Electrical eff…
Conditions for Parallel Operation of Dc Generator : To connects the generators in parallel to common bus-bars, the generators should satisfy the following conditions. The incoming generator's voltage should be the same as t…
Lap Winding : When the winding is connected in such a manner that the end of the one coil is connected to the starting end of other coils (adjacent coil) of the same pole and so on then the winding is known as lap winding. Lap…
There are two methods of improving commutation i.e., for making current reversal in the short-circuited coil as sparkless as possible. They are, Resistance commutation. EMF commutation (it is done with the help of brush-lead or i…
Based on the methods of the interconnection of windings the following types of dc generators are available. Separately-excited DC Generator Self-excited DC Generators Shunt-field connection, Series-field connection, and Compound-…
We know that the working principle of dc generator, that when conductors begin to cut the magnetic lines of force and therefore, the e.m.f. induces in the conductors according to 'Faraday's Law of Electromagnetic Inducti…
Working Principle of DC Generator : A simple coil of wire ABCD is mounted on a shaft between two magnetic poles. The two ends of the coil are connected to two slip rings, S 1 , S 2 which are mounted on the same shaft. The slip …
