STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[lumen]

Well, I just attempted to do it, but the darn tiny orbo keeps on going. I had to stop it at 5000 rpms in fear that the glued magnets will shoot off, lol. The rpm just kept going and going.

When the bcap0650 voltage gets low enough, then maybe it will reach a maximum rpm, and I'll try it then.

Thanks for trying. I was thinking that as the windings progress around the core, it makes a single loop of wire that would cause a field that could work like a standard pulse motor.
It is likely that a single wire loop would produce only a very small field and could be nearly undetectable.
Thanks again,

Wow, Jimboot, I can't thank you enough. Thank you so much! I love the graphics screen shot. That's the best way to do it. I owe you one. 

Regards,

Well I wouldn't mind a copy of your mosfet circuit (I understand if your too busy solving world energy crisis)

No problem. See attached image. It's nothing fancy what so ever, but just something I sloped together. Lots of improvements. 

I have to agree though that a relay will have less losses than mosfet, at least an IRF540. Maybe you have a mosfet with less resistance. Do you know of any efficient high-speed relays that would work well for this?

Wow thanks. You have mistaken me for someone that has a clue. I don't know even how to spell high-speed relays!

Paul, the IRF540 on-resistance is something like 0.07 ohms.
Are you sure it is switched on/off properly?
Switching off an IRF540 is not simple. It takes me a heavy driver to do that properly (I use UCC27322p )

Also, if you use a diode in parallel (flyback) with your coil it's even more effecient. By this you can switch off earlier in time.
