I don't think it's so bad.
Remove the extra motor related stuff ("Thermally Protected" and that spring do-hicky), split the wires (maybe the yellow wire goes to 2 wires), make room on the rotor for 4 magnets (or magnet poles), add magnets, and it'll work.

I do not mean to imply it is great. I mean it isn't too hard to make something that works. I am happy if it works well for the time and cost (hobby) until the next one replaces it.

Master Zubbly (RIP) would only use 3 phase motors for a serious project that did not require rewiring.

Got it? Try it.
Worst case it learn a lot for something better.
Two cents.

V-man, It seems I am the last active member for "down&dirty / add some neos / make some power".

Just so you and everyone else knows, sometimes it ain't so great.
Latest effort: New USA 20" box fans have a new motor, I tried, it's no good, 38ma at 12V and 650RPM. The new motor is a lot different, tiny, and not great.
The unmodified factory rotor, with 2 types of proposed neos, shown here...

But it works.
Still waiting to hear if the guy wants to trade me for something nicer. LOL

So yes, the one JW shows is not so bad, IMHO.

The world is still OK!

Hi Ghurd,
Down and dirty types learn alot more than people that have small fingers an can type with two hands.

It's all in fun and your a great inspiration for me.

Thanks.
Mark

Yes. The old-style box fans where pretty nice.
The new-styles are not.
"Cheap" 1150 RPM single speed vent fan motors
should still be fine, and probably better.
Looks like an old-style box fan motor, but thicker.
