17+ pages how to reduce armature reaction in dc generator 1.8mb. It reduces the magnitude of the main field flux. Armature reaction is the shift rotation of the neutral plane of the dc machine stator magnetic field caused by the magnetic field from the currents in the rotating armature. Now consider the conductors lying within the angles AOB COD 2 at the top and bottom of the armature. Check also: generator and understand more manual guide in how to reduce armature reaction in dc generator In a dc generator the purpose of field winding is to produce a magnetic field called main flux whereas the purpose of armature winding is to carry armature currentAlthough the armature winding is not provided for the purpose of producing a magnetic field nevertheless the current in the armature winding will also produce magnetic flux called armature fluxThe armature flux distorts and weakens the main flux posing problems for the proper operation of the dc.
One easy and simplest way is to shift the brushes to the new position of the magnetic neutral plane. What is armature reaction.

Thus by increasing length of air gap the armature reaction effect is reduced.
They carry the current such that the flux produced will flow from right to left. This increases the reluctance of the pole tips which reduces the magnitude of armature cross flux and hence armature reaction is minimised. Now we know that the armature reaction is due to the presence of armature flux. Armature Reaction in DC Generator. These currents flow in one direction when armature conductors are under N-pole and in the opposite direction when they are under S-pole. By using high brush contact resistance with the commutator segment undergoing.

Consider the figure below shows the two poles dc generator. The armature reaction causes the distortion in main field flux. These currents flow in one direction when armature conductors are under N-pole and in the opposite direction when they are under S-pole.
Here is all you need to read about how to reduce armature reaction in dc generator Methods to reduce Armature reaction in DC Machine Interpoles are similar to the main field poles and located on the yoke between the main field poles. This increases the reluctance of the pole tips which reduces the magnitude of armature cross flux and hence armature reaction is minimised. Usually no special efforts are taken for small machines up to few kilowatts to reduce the armature reaction. Reduce armature reaction in dc machine electrical idea methods of reducing armature reaction in dc generator methods of reducing armature reaction in dc generator armature reaction in dc machines armature reaction in a dc generator its effect circuit globe methods of reducing armature reaction in dc generator But for large DC machines compensating winding and interpoles are used to get rid of the ill effects of armature reaction.
