Hello!,

As an engineer who graduated #2 out of 10 in my class from a top tier university, yet I am completely, 100%, stumped on this electronics project and feeling like I a complete doo doo head and I am in dire need of help from my nerd comrades.

What I am trying to do is increase the RPM’s of this fan motor. Right now it has a 4 setting selector switch (off, speed 1, speed 2, and speed 3), but I need more power or RPM’s then the highest speed setting (speed 3) will give me. A picture and all the details is attached, anyone who can solve this problem I will worship you! Just let me know the parts and wiring and I will turn your words into a finished project.

If the rpm’s can not be increased using the motor I have now – then please let me know an easy motor setup I could install to give me more RPM’s then the current setup.

Thanks a ton guys!

Was going to post this within material engineering, but since you guys are being so helpful I will post here.

Can anyone tell me a plastic or cheaper to manufacturer alternative to this design - 7'' diameter circle made out of spring steel wire that easily deforms and returns to circle shape. It needs to able to simply crumple it up in your hand and then release and it springs back to original shape.

Please see video for more information (in the video it is enclosed in fabric)- Link
 
I'm not sure that you are truly deforming the steel. Most windshield shades cannot tolerate true deformation of the steel.

There is, however, one material that can do something similar, called shape-memory alloy, one of which is known as nitinol. You can see it here But, you need to apply heat to it for it to "remember" its original shape. I had a couple of strands of it. It's pretty cool.
