Designing + Building A Generator. :O (1 Viewer)

[iheartzyou]

For my physics assignment, we must Plan and perform a first-hand investigation to demonstrate the motor effect and magnetic induction. \=

So basically, we need to design and build a generator.

Any ideas on how to do this and where to start Websites and other sources are also helpful. Thanks!

If you're going to answer like that... don't even post at all


that doesn't help the OP whatsoever.


and to OP, are you sure there is a dot point 'Plan and perform a first-hand investigation to demonstrate the motor effect and magnetic induction' ???


there's only 'Plan and perform a first-hand investigation to demonstrate the motor effect'

Huh? to build a generator? Thats not what this" Plan and perform a first-hand investigation to demonstrate the motor effect and magnetic induction. \=" said

Though if you do manage to build a generator, that'll be cool. It does sound like you're going to have to buy some crap though

There is, I think he meant the magnet and coil one

"perform an investigation to model the generation of an electric current by moving a magnet in a coil or a coil near a magnet" ????


Well that's not what the OP posted.

Sorry For The Late Reply.
But what i wrote as the first post is what the teacher gave to the students -.-'
Also, I think Plan and perform a first-hand investigation to demonstrate the motor effect and magnetic induction is just one dot point, but the teacher edited it.

But thats not important at the moment :\
I just need help in building a simple generator that produces voltage, thats it.
I just dont know where to start and i need a procedure to help me ):

Thanks Again.

I Think that is the dot point our teacher was referring to. .

Pretty sure the motor effect only applies to motors not generators.


But to build a generator you need:


Stator: permanent magnet or electromagnet. Electromagnet is better because you can switch it on or off.
Rotor: Armature and the coils wounded onto it.
Battery or power supply
Connecting wires

AC gen: Slip rings
DC gen: Split ring commutator



As for the design, it's same as a motor. A typical DC motor's design applies for DC generators:

As for the equipments, I presume your teacher will supply the equipments for you =)

As for the guide in how to build it... I presume your teacher will give you a manual =P

If not check this out: http://www.ehow.com/how_4843047_build-dc-generator.html


Oh and there is a simple AC generator and much more sophisticated ones like the three phase generators. Because it's a high school assessment, just focus on the simple AC generator. Sorry I can't find a guide for building an ac generator =(


Remember: Generators generate EMF by induced torque. So perhaps you'll need some sort of handle on the rotor to rotate the rotor =P

I was thinking that as well with the motor effect, but i guess our teacher may be referring to the rotation of the coil? I dont know. ={

Also, i know what equipment is needed and what a simple generator looks like and how it works (thanks for the picture by the way =]), its just how do i put all the equipment together hehe. =\

So I think this website you gave me: http://www.ehow.com/how_4843047_build-dc-generator.html should help =D

And our teacher didnt give us equipment or a manual to build the generator ):
It was simply just to design and build a generator LOL. d=

But thanks for your help jamesfirst, i couldnt have done it without you. :L
and dont be sorry about finding a guide to building an AC generator, you have helped enough ;].

 

[jamesfirst]

In our school, we only built DC motors.


And manual came with the equipment...


We didn't build a generator. lol

Well that's not what the OP posted.

Magnetic induction is vague. I thought he didn't express it correctly
