Why thick wires are used for Series field winding than shunt field?
When compared to shunt field windings they are thicker because the series windings carry the same current as the armature so a low resistance of a thick wire is an advantage.
What is difference between armature winding and field winding?
Armature Winding is the winding, in which voltage is induced. Field Winding is the winding in which the main field flux is produced when the current through the winding is passed.
Why field winding of shunt generator is made thinner and has more 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.
Why a thicker wire is used in the DC series field winding than DC shunt field winding in DC machines?
The resistance of the shunt field winding as compared to series field winding is ____. A 250V DC shunt motor takes a total current of 20A….
Q. | A thick wire is used in dc series motor field winding than that in dc shunt motor: |
---|---|
A. | to create more flux |
B. | to reduce the resistance |
C. | to carry large load current |
Where is commutator used?
Commutators and brushes are used on all DC generators and DC motors. They are also used on some AC motors such as the repulsion, synchronous, and universal motors. All generators produce a sine wave, or AC currents when the rotor turns in the magnetic field.
Which motor has a few turns of thick wire and resistance is kept very low?
Series wound dc machines – In this type, field winding is connected in series with the armature winding. Therefore, the field winding carries whole of the load current (armature current). That is why series winding is designed with few turns of thick wire and the resistance is kept very low (about 0.5 Ohm).
What are the advantages of providing the field winding on rotor and armature winding on the stator?
What are the advantages of providing the field winding on rotor and armature winding on the stator? Explanation: If the armature winding is on the stator, only two slip rings are required which implies less losses, more efficiency and more economy. Also, stationary armature winding can be cooled more efficiently.
What is meant by the armature windings and what are they used for?
The armature winding is that which generates or has an alternating voltage applied to it. Usually, the terms “armature” and “field” are applied only to alternating current generators, synchronous motors, DC motors, and DC generators. Thus, the armature is the stator and the field is the rotor.
What is shunt field winding?
Main or shunt field windings are used to control no-load output of a generator. A filter reactor or an inductor is replaced with several turns of a series winding on field poles of the rotating generator to provide inductance for stable arc.
Which winding has more resistance in DC shunt motor?
field winding
Keeping these two above mentioned criterion in mind a DC shunt motor has been designed in a way, that the field winding possess much higher number of turns to increase net flux linkage and are lesser in diameter of conductor to increase resistance (reduce current flow) compared to the armature winding of the DC motor.
Why the series field winding is made up of thick wire?
Why the series field winding is made up of thick wire and fewer turn and shunt field winding is made up of thin wire and more turns in dc motor? In a DC motor Armature current is dependent on load connected to the motor shaft. Higher the load higher the armature current.
What is the difference between armature winding and field winding?
Armature Windin g is the windings, in which voltage is induced.The Field Winding is the winding in which the main field flux is produced when the current through the winding is passed. Some of the basic terms related to the Armature Winding are defined as follows: Turn: A turn consists of two conductors connected to one end by an end connector.
What is the difference between series field winding and shunt field winding?
Register now or log in to answer. Series Field winding carries high current so conductor size increases (thick wire) whereas shunt field winding carries less current hence (thin wire) . The size of the conductor (coil thickness) is related to the size of the current that can pass through it. We can see from the ampacity of this conductor.
What is field field winding?
Field Winding is the winding in which the main field flux is produced when the current through the winding is passed. Some of the basic terms related to the Armature Winding are defined as follows:
