What type of DC generator that is made up of fewer turns of heavy wire?
Series Wound Generator The series field winding consists of a few turns of wire of thick wire of larger cross-sectional area and having low resistance usually of the order of less than 1 ohm because the armature current has a very large value.
Which winding has large number of turns shunt field?
Explanation: The shunt field winding is provided with a large number (hundreds or even thousands) of turns of thin wire and is excited from a voltage source. The series field winding has a few turns of thick wire and is excited from armature current by placing it in series with armature. 2.
What is a shunt field coil?
Main or shunt field windings are used to control the no-load output of a generator. A filter reactor or an inductor is replaced with several turns of series winding on field poles of the rotating generator to provide the inductance that is required for a stable arc.
What is shunt wound?
Definition of shunt-wound : wound so that the armature winding and field winding are in parallel a shunt-wound direct-current generator.
Why field winding of shunt DC motor has higher number of turns?
The shunt (field) windings of a DC shunt motor are made of smaller gauge wire, but they have many more turns than a series-wound DC motor. The high number of turns allows a strong magnetic field to be generated, but the smaller gauge wires provide a high resistance and limit the current flowing through the shunt coil.
What is a shunt field winding?
What is the difference between short shunt compound DC generator?
Short Shunt compound dc generator is in which only shunt field winding is in parallel with the armature winding. Long Shunt compound dc generator is in which shunt field winding is in parallel with both series field and armature winding. 3.1. Long shunt Compound Generator
What is a compound DC generator?
A compounded d.c. generator has both a shunt and a series field winding. Usually the ampere-turns of the shunt field are greater than those of the series field when the latter is carrying rated current. Fig. 3.27 (a) and (b) illustrate the two methods of connecting the field windings to the armature.
What is a shunt connection in a generator?
The shunt connectionis in which the field is connected in parallel, or shunt with the armature. The voltage from the armature is applied directly to the field in the case of a generator, while for motoroperation the source voltage is applied to the field and armature.
What is a shunt wound DC generator?
Shunt Wound DC Generators. In these type of DC generators, the field windings are connected in parallel with armature conductors, as shown in the figure below. In shunt wound generators the voltage in the field winding is same as the voltage across the terminal.
