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.
Which is usually produced by a generator ac or DC?
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
Explain the construction and working of simple loop dc generator?
construction of DC generator
Why DC motors and DC generators are commonly known as DC machines?
because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.
What is a DC generator the same as?
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
What is critical resistance of the field circuit of a DC generator?
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.
How you control the speed of self excited dc generator?
Easy. By controlling the speed of the motor or whatever is turning the generator's shaft.
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.
Different types of DC generator?
There are two types me dc generator 1 separately excited dc generator 2 self excited dc generator
How is the induced voltage of separately excited dc generator affected if the speed increases?
as speed increases, induced voltage increases
Which is usually produced by a generator ac or DC?
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
What are the possible reasons for failing the voltage of a dc shunt generator to build up during starting?
Possible reasons for failure of voltage buildup... 1) No residual Magnetism, 2) Field connection may be in reverse manner, 3) Field resistance is greater than critical resistance, 4) Speed is less than Critical speed.
What was the first DC generator name and inventor why it is call generator?
first dc generator is max generator donno who invented t
How do you make DC generator?
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
Types of generators?
By the operation supply 1.AC generator 2.DC generator In DC generator we are having the following types according to the construction 1.DC Series Generator 2.DC shunt Generator 3.DC Compound Generator
Explain the necessity and principles of commutator in Dc generator?
what is necessity of commutator in DC generator
How do you convert a DC generator to ac alternator?
Turn the DC generator inside out and you have an alternator .
