3. series dc generator A series dc generator is a generator whose field is connected in series with its armature. Since the armature has a much higher current than a shunt field, the series field in a generator of this sort will have only a very few turns of wire, and the wire used will be much thicker than the wire in a shunt field. • Fig

DC Generator Parts, Working, EMF Equation, Types

The emf equation of the DC generator is given by the equation: \(E_g=\frac{P\phi ZN}{60 A}\) where. Z is the total number of armature conductor. P is the number of poles in a generator. A is the number of parallel lanes within the armature. N is the rotation of armature in r.p.m. E is the induced e.m.f in any parallel lane within the armature. E g is the generated e.m.f in any one of the

Difference Between AC and DC Generator In Tabular

In a DC generator, the electrical current flows only in one direction. 3. Basic Design. In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less. In a DC generator, the coil through which the current flows rotate in a fixed field.

AC Generator : Working Principle, Construction & Its

An AC generator is a device that converts mechanical energy into alternating electrical energy for appropriate use. Based on the type of power input, there are two types of generators AC generator and DC generator.Slip rings are used in AC generators to produce alternating current, while direct current is used in DC generators.
