Motors, Generators, Supply, Rings!

OK so there's 2 generators AC and DC, but 1 motor which is DC only
I want to clarify if this is right

AC generator: Slip ring+AC current (AC referring to the production of AC)
DC generator: Split ring+AC current (DC referring to the production of DC)

DC motor:Split ring+DC

Ac generator - correct.

DC generator: Split ring+AC current (DC referring to the production of DC)

a DC generator doesn't produce an AC current.

DC motor - correct , however i think you can use AC current but you need to have electromagnets (not sure about that)

I mean in DC generator you need to use AC to produce DC?
Do DC generator can use AC but need electromagnetics


Ac generator - correct.

Umm... a generator produces current...

What happens is you have a wire coil inbetween two magnets. This coil is made to rotate by an external force such as steam
This rotation produces a change in flux which then induces a current in the wire coil.
The split rings cause the current to always be in the same direction by alternatively connecting each end of the wire with each half of the split commutator and produces a DC current.

[kenhung123]

Oh so motor is the one using current!

[kenhung123]

Is it ok to think that slip ring leaves the current as it is (AC) and DC reverses the negative current

[Whatlol]

Correct, the rotor moves as a result of the magnetic force acting on the current flowing through the coil.

Whereas a generator has a current induced in it.

The slip rings dont really do much so yes you can just think they leave the current as is.
What they exactly do is allow the induced current to flow out into an external circuit, because the coil rotates in a circle, you need some kind of a ring so it has a constant conducting path. ( imagine what would happen if you just connected the coil to wires... they would just tangle up heaps). At least.. thats the way i view it.

And yea the split rings just ensure the current is always flowing in a constant direction.

Oh lol I actually did not notice that! Thanks!

Edit:just to clarify commutator=split ring ? They can be used interchangeably or?

Well a split ring refers to a split ring commutator (im fairly certain), so basically a metal cylinder which has two halves. each halve has a carbon"brush" attached which is used to conduct the electricity.

So umm if I want to talk about split ring I can say 'commutator' and they won't think its slip ring right?

Hmm.. if your talking about something requiring split rings i wouldnt just say commutator. I would be extremely specific and say a split ring commutator. or even just say split rings.

Oh because Q98 just said commutator and i said split ring i thought they were same

Yea it basically is but i always write split ring commutator basically because my teacher wants me to.
