Want to know about two point starter?
In DC series motor, field and armature are in series. so we use only two points. They are line and armature. therefore we use two point starter.
What is the difference between armature reaction and armature reactance?
armature reactant means loss in armature associated with inductive properties of the coil, while armature reaction include losses due to magnetizing component of current flowing through armature.
Is it true that large generators use armature similar to those in a motor?
yes
What are the values of armature and field rheostat to be maintained during starting of a d.c motor?
you want full field while starting 0 Ohms and maximum series on armature then bring the armature resistance to zero as it approaches running speed its a good idea to run with armature at 0 ohms armature will use the same amount of power as the resistor If you want to run at more than base speed you can now weaken the field
Difference between 12volt armature and 24 volt armature?
24 volt armature is accept balancing cut
Why dc shunt generator does not have armature resistance?
It does have armature resistance.
What is mean by armature reaction?
armature reaction means when load is added to the armature then current is passed through armature conductors then in armature creates flux. It is demagnetize and cross magnetize the main field flux. in other ward it is effect of armature field on main field.
What do you use magnetic for today?
well you use a magnet to lots of things... from handbags to compasses!!unistation 360 plz like
What is the use of magnetization curve of DC shunt generator?
The armature voltage is a critical parameter in the determination of performance characteristics for the DC machine. The armature voltage has been shown to be proportional to the magnetic flux density per pole and the armature speed. Thus, the armature voltage will also exhibit nonlinear behavior when saturation occurs. The analysis of DC machine performance typically requires that the characteristics of the armature voltage saturation be known. This information is typically provided in a plot of the armature voltage vs. field current (magnetization curve) for a given operating speed
What are the effect of armature reaction in DC machine and how the armature reaction is minimise?
Armature reaction is the interaction between the magnetic flux produced by armature current and that of the main magnetic field in an electric motor or generator.
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 the function of armature core in dc generator?
this is wer the armature conductors ar being mounted,therefor it helps the flexibility of armature conductors.
