What is armature reactions in a synchronous machine?
Armature reaction is the effect of armature flux on the flux generated by the fied windings.Cross magnetisation and Demagnetising are its consequences.
What is armature reaction in dc motor?
Armature reaction is effect of armature flux on main field flux. Basically there are two windings in a dc motor - Armature winding (on stator) and field winding (on rotor). When we excite the field winding, it produces a flux which links with the armature. This causes an emf and hence a current in the armature. This current in armature produces another flux which lags the main flux. This is referred to as armature reaction. It has two effects on the machine: 1. Demagnetising effect: It reduces the strength of the main flux. 2. Crossmagnetising effect: Its effect is that it bends/distortes the the main flux line along the conductor
What is a cause and effect for The Wounded Wolf?
I have homework so I have to write 3 cause and effect for the story "the wounded wolf." Can someone help me please.
Why are the compensating winding used in dc motor?
compensating winding is used for equal load sharing of two generators running in parallel. while interpole winding is used to minimise the effect of armature reaction by supporting the main field.
Does the stacking effect of Winding Constrictor enhance the abilities of multiple instances of the card on the battlefield?
Yes, the stacking effect of Winding Constrictor enhances the abilities of multiple instances of the card on the battlefield by increasing the number of additional counters placed on creatures and other permanents.
Can you do without a capacitor in a ceiling fan?
No, it is the capacitors effect upon the motor's winding that starts the fan to turn.
What effect did the battle of wounded knee have on native American?
over land
What is the use of interpoles in dc machine?
Interpoles are similar to the main field poles and located on the yoke between the main field poles. They have windings in series with the armature winding. Interpoles have the function of reducing the armature reaction effect in the commutating zone. They eliminate the need to shift the brush assembly.
What are compensating winding?
compensating windings are used to overcome armature reaction
What was the effect of Johann Gutenberg's new machine what did it make possible?
What was the effect of Johann Gutenberg's new machine?The effect of Johann's new machine was because ideas spread more rapidly. Books dropped drastically in price. Also Literacy rates increased.
What is demagnetising effect of DC generator?
demagnetising effect of dc generator is to reduce main field flux there by reduction in generated voltage.
