AC generator and DC motor

[Over9000]

Are the only differences between an AC generator and a DC motor the fact that an AC generator is run using kinetic energy (or external force) rather than electrical and the fact that DC motors use split rings as apposed to slip rings used in AC generators? If so, why is it possible to have the coil in the generator spin without split rings whilst the DC motor needs split rings to reverse current otherwise it oscillates when it is vertical?

EDIT: Also, why does a DC motor generate kinetic energy while an AC generator generates electical energy when it seems they do the same function of rotating a coil in a magnetic field?

DC motors use split ring commutators.

AC generators use slip rings.

DC motors use split ring commutators.

AC generators use slip rings.

I know that but as my op said, why does this lead to different types of energy produced and why is it possible to use slip rings on an AC generator and not need split rings?

Slip rings ARE used for AC generator, not split rings.

Sigh, I know. Im asking, why they can be used if the makeup of the AC generator is the same as the DC motor (coil rotating in a magnetic field), in the case of a DC motor only split rings can be used, using slip rings results in oscialltion at its vertical. So why is it possible with a design that looks very similar (AC generator) to now use slip rings effectively?

Also, why does a DC motor generate kinetic energy while an AC generator generates electical energy when it seems they do the same function of rotating a coil in a magnetic field?

You have answered the question yourself.

split rings in generator => DC generator.

Dictionary is your best friend.

Or you can type the following into google:

Define: motor

Define: generator

All in what? 10sec. LOLworthy.

ANyway, if you havn't gained any insights since your first post (things seem to evolve pretty fast around here) then in an AC generator it still moves... well... because you want to make it move. The electricity that's being generated is a result of this movement. In a DC motor however you can't help to make it not turn around unless you put in a split ring.
Split rings and slip rings can both be used in generators, as discussed in TT's thread, you may want to check that out and then leave specific questions here later

Right, coz clearly I asked what is a motor and what is a generator?
LOL wdf happened to my quoting?

Motors:
- Split rings (DC) swap which terminals the ends of the coil touch every half-turn, so current reverses and torque is maintained in same direction.
- Slip rings (AC) can be used if the frequency of AC current is exactly right so as to switch current direction every half-turn, but pretty impractical.

Generators:
- Slip rings (AC) keep each end of the coil attached to a particular terminal in the external circuit. Every half-turn the current in the coil reverses, and by keeping the same connections using slip rings, the current in the external circuit will alternate with the same frequency as the current in the coil.
- Split rings (DC), these change connections every half-turn, but current also reverses direction every half-turn. This results in pulsating DC in the external circuit.

Motor electricity => kinetic

Generator kinetic => electricity

If you use split ring in generator

y = Q|sin(ax)| occurs.

slip rings:

y = Qsin(ax)

Okay but why does the use of split rings give you kinetic energy and the use of slip rings gives you electrical energy even tho both of theyre functions is spinning a coil in a magnetic field, shouldnt they both create an induced emf and create electrical energy? Just wondering

You have wondered correct, they do both created induced EMF.

Motor electricity => kinetic

Generator kinetic => electricity

In your jacaranda do you see a battery source on the generator? I don't think so.

You use external force to turn generator

A back emf is created from the current to oppose the torque created by the external force.
