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
