Magnetic Current Flux Switching Alternator

[Boxerlego]

I tore apart a chainsaw and found this metal guy and now I'm going to build a magnetic current flux switching alternator with it.

Be careful not to go too far back in time those flux capacitors need 1.21 jigawatts to get Back to the Future.

I think that 'metal guy' is called a sprocket :)

This machine I posted in this thread is the technology that apart of technology that will without doubt send everyone back in time. Tips for the Rocket People.

Yes your right and for this magnetic application it is know as armature. This armature here is best suited at making Alternating Currents but the DC motor armatures is timed to make Direct Current.

I stop building on the flux switching generator right now. I decided to make something else and use magnets on the armature. I've already completed it.

There should be more magnets in lego, not that there is any, they can be used for all sorts of floaty type cool stuff.

[Boxerlego]

I agree, currently the only way to build with magnets is through the DC motor. It would be amazing to see a building block magnet that is for lego. Something that is both particle and can be use in conjunction with the wide list of lego DC motors and have the feeling you can build anything with those magnets take for example this 3 cylinder solenoid engine.

Is there a video of that in action? Looks Great!

PiterX is looking for a way to drive a lego piston engine for use in a moc in exactly that kind of mechanical way, could that be smaller and is the lego power supply enough to work it, just out of curiosity?

[Boxerlego]

Thanks, Here is a video of it in action. I use two power sources in the video to power it in the video, the first power source I use is the lego 9v battery box and then the second power source I use my 19v 7000 ma laptop power supply. It could have performed better if there was not a there is a thick layer of pvc tubing between the magnets and the coils.

Thats fast and quiet considering the centrifugal force is spinning the whole assembly around on the table, the pneumatic engines require separate compressors to go at any decent speed but this is can be self contained in a moc.

that is freaking awesome! Spins so fast!

Thanks, Even though I am using this a motor one of the other ideas is to use it as a generator but because of the pvc tubing layer between the coils and the magnet the generator power is not in full force... I haft to design a set of generator coils so the magnets can be used to there maximum effect.

Thanks, I can make it spin faster if I time the other side of the magnetic swing. but doing this requires more transistors

So this could done to a standard lego engine, like a v8?

After looking at the lego parts the engine blocks have spaces near the top for a thin wire coil, and then possibly glue magnets to the lego pistions.

[Boxerlego]

Using magnets as piston has its draw backs, first major draw back is that the magnet piston will attract or repel each other so close piston spacing is a definite problem when dealing with those magnetic forces. So no this could not be use with a standard lego engine like a V8.

Oh well, I still want to try magnetic suspension with neo magnets some day, hmmm your system could be used for active suspension, hmmm I have too many daft ideas.

[Boxerlego]

Are you referring to magnetic suspension system for vehicles. That is some technical stuff. Just look at this wiki on magnetic actuators.

[JM1971]

Those actuators are really smooth and I should think have less mechanical wear than screw actuators, I think lego technic is due for more advanced stuff.
