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

Why dc shunt generator can not induce any voltage with rated speed?
Two things could have occurred. (1) wrong direction of rotation causing loss of residual magnetism or (2) loss of residual magnetism over long period of no use. can be remedied by "flashing" the shunt field winding howlumf
How do you calculate power use for a home power generator?
Click the link. There you can figure the size generator you need.
Why use maximum resistance for starting dc shunt motor?
because there is ahigh current flowing through it at the start...
Why the windings of an ammeter should be of thick wire?
because lots of current is likely to be flowing through them.however a shunt ammeter is easier to build than the direct ammeter as described above. in a shunt ammeter you use an ordinary meter wound with fine wire and put a small value shunt resistor across it to take almost all the current.
What the Generator lockout relay?
generator lockout relay is a relay that the output of other relays energize this relay and its out put use for tripping of generator. this relay must be reset manually
What would happen if a shunt-excited DC generator was operated at too low a speed?
A shunt generator is a type of DC generator that does not use a permanent magnet. Reducing the speed of the generator will reduce the output, but not the load the generator requires because the currents in the parallel branches are independent.
Can you use the separately excited shunt generator machine as self excited generator?
You have a seperately excited generator and then you have a shunt generator which has the field winding in parallel with the armature terminals. In DC machines a separately excited generator could be run as a shunt generator provided the field winding is designed to work on the generated voltage. A separately excited alternator needs a DC supply for the field winding. In car alternators that is taken from the main winding via a rectifier and a voltage regulator.
How do you use shunt in a sentence?
The word 'shunt' is both a noun (shunt, shunts) and a verb (shunt, shunts, shunting, shunted).Examples:He had to have a heart shunt put in. (noun)The engineer will shunt the train onto that track instead. (verb)

What happens if you draw to much current from a shunt generator?
You get a giant explosion. To use it's scientific name, "BOOM!". Do not stick a fork in it under any circumstances. Ze little cartveels vill explode in your face. It vill however be funny for your friends to vitness.
Can you use the ansul system contacts in a kitchen to break the cooking circuits with the shunt trip breaker?
Yes, you can. If your shunt trip is 120 volts, just get 120 volt from your panel and take it to your ansul normally open contacts than to your shunt trip braker. than when your ansul system trips it will trip your shunt braker.
Why you not usually use induction generator?
we do not use induction generator because it require an external source (synchronous generator) that provide reactive power to it.
What are fans powered by?
Most fans have an electric motor that runs off of electricity. These use magnetization to spin the fan
What type of DC motor fan use?
shunt type dc motor use in train fans
Can a missile be fired by use of generator?
yes a very big generator
Can you use molded breakers instead shunt trip breakers for an Ansul fire suppression system?
Moulded breakers or shunt trip breakers - selection is defined by the current rating requirement.
