A DC generator has a commutator, a rotary switching system, that connects a different winding of the rotor, for each fraction of a turn. Thus keeping the polarity one way only. The stator windings are fed a proportion of the DC generated, to make an electromagnet. The power is taken off from the rotor via the commutator switching system.
An AC generator supplies the rotor with a DC current, via slip rings on the shaft, to exite it. (Makes the rotor an electromagnet) The power is taken off from the stator windings and alternates from one polarity to the other, as the rotor turns inside, producing AC and not having to go through a switching ystem.
What else can I help you with?
Does a generator produce ac or DC voltage?
NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.
How do you convert a DC generator to ac alternator?
Turn the DC generator inside out and you have an alternator .
What determines the output frequency of an ac generator?
It's speed and the number of poles.
How is a Load applied to a ac generator?
The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.
What is difference between generator and oscillator?
A generator is used to convert mechanical energy to electrical energy. An oscillator is used to convert dc to ac
What is one invention that Thomas Edison seemed to keep working on?
ac generator
Ac generator construction?
what is the construction of ac generator
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 would happen to the output of an ac generator if one of the stator windings has open?
There would be a significant decrease in the output of the generator. Depending on the type of generator, it could stop working altogether.
What would happen to the output of an AC generator if one of the stator windings has an open?
There would be a significant decrease in the output of the generator. Depending on the type of generator, it could stop working altogether.
When do you know when a generator is working?
Depending on the type of generator, you can measure the voltage at the output. Assuming it's a regular 120 volt AC generator, the output should measure 120V AC. If it doesn't, you may have problems.
Does an alternator work similar to an ac generator?
Alternator and ac generator is equal
Does a generator produce ac or DC voltage?
NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.
Is dynamo an AC generator?
DC generator
How do you step down frequency and voltage from an AC generator?
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
What is another name for an ac generator?
an induction generator
Is ac power produced first in a dc generator?
It can be, however AC power is generally produced directly by an AC alternator/generator.
