Need Help!- Coil of Wire

[mechfries]

PROJECT TITLE- INTEGRATION OF FARADAY'S LAW INTO PISTON DESIGN

sup engineers....

My group is working on a project of internal combustion engine project. What our project basically is we added a magnet under the piston to improve efficiency because, if our plan goes right, there will be no need for an alternator nor starter moter. I ok with inventor and below is the CAD drawing I have made thus far. It rough draft drawing


So know you know what I'm trying to do, I need help in the following

• Making a coil of wire to surround it so when the piston goes down, voltage will be induced
• Animate it, one of the animation to be moving up and down I know there loads of tutorial how to do it but I want to also be able show nice graphic of current arrows being generated
• I want to perform heat and electromagntic analysis on it to see how the field is affected, softare which I have right now are ansys and COSMOL.

thanks in advance.

see attachemnt of the cad model drawing. i can't attach ips or dwg ... sucks

can someone please tell me how to make a coil of wire in inventor?

Interesting idea but have the permanent magnet and other magnetic materials got a sufficiently high curie point? The curie point can be as low as 375 degrees Celsius for some magnetic materials. Looks to be a terrific idea if it can be realized in an engineering environment.

Good luck - regards - Pat

PS to get a high magnetic conversion efficiency the gaps will have to be very small and will collect particles of a magnetic origin that happen to be in the vicinity. However I am not knocking your inventive ideas as it is out of this type of brain storming that new technologies / machines arises.

Well on wiki Neodymium magnet - Wikipedia, the free encyclopedia some of the magnets have curie temp of 800 e.g. Sm(Co, Fe, Cu, Zr)7 (sintered

Yes you can pick high curie point magnets but they have other properties that make them difficult to deploy in an engineering context. As a general observation the stronger the magnetic properties the weaker and more brittle the magnet. As this is a concept project there are also resource implications for the rare earth elements to consider.

Wish you every success with this as it is indeed innovative design idea. Regards - Pat

thanks i will keep in mind.

Don't know about the other stuff much, but you asked how to draw a coil..
Here is how:
- Create new sketch, on for example Front plane.
- Project origin (Center Point)
- Draw a circle to the right of the center point
- Constraint (Horizontal) the circle center with the center point
- Dimension the circel diameter to the wire diameter you want
- Make a dimension from center point to the circle point. (This will be the coil radius)
- Return (exit sketch)
- Click on "Coil" in the tool panel
- Click "Profile" and select the circle
- Click "Axis" and select the Y axis (in this example)
- Enter parameters (pitch etc etc) to desired values
- Ok

Hope that helps?

Thanks... I did get a coil but it wasn't the type i was looking for.

What important now is how do I simulate 3dmagnetic field with heat transfer in ansys for comsol?

[hub]

To be honest I have no idea.. I have never used ansys for comsol. I don't even know what it is.. Guessing a simulating software.
But simulating programs in general would not all require that you would have to have the coil modeled in 3D? Would it not be enough with mH etc? Number of turns, diameter, wire diameter, length?
Sorry I can't be of more help than this.

[hub]

Also, I forgot to mention. Because you said it was wrong type.
I'm guessing you want a "normal" coil with multiple layers (turns)?
- Set the parameter "Taper" to a suitable angle
- Make a new sketch and project the existing wire circle, and repeat the same steps for each turn. The result would be a 3D coil with many turns (I'm guessing the single coil, "spring", is the wrong type?)
- Repeat until done

Thanks though but I need to show are magnetic field changing due to heat transfer with crude results. I don't need accurate results but result enough to proof a point.

Any other software which can do this will help.
