Hi Dave, I'd call this a great excuse to buy a lathe...it's the one I'm using! Also; a question to the group: Is this technology patented? I had contacted a...
... Yup, but it's either a lathe or an Feda helicopter -- too many choices ... Hmmm.. Can you elaborate on that -- I had missed the thickness effecting the...
Dave, I'm a little weak on magnetic flux/eddy current theory...but did some websearches and found some university Physics department pages on the subject. The...

Hmmm.. I hadn't thought about it, but that makes sense. I had assumed that the plate method of stator construction was for manufacturing ease (much like the...
I think there is also a trade-off of metal thickness vs. the insulation thickness, as the plates need to be insulated. You still need to have enogh metal to...
Hi Dave, actually, the thickness is largely dictated by the frequencies used in the windings. Making the plates thinner than the penetration depth (can't be...
Hmmmm....more research! The learning is almost as much fun as the building! Can anyone give a nudge toward an English website? Best Regards, Scott...planning...
Hello I have a 10mm thick CDROM stator and 5x5x1.8mm magnets. Can I join the magnets end to end to give the 10mm required or would that not work? thanks...
Yes, you can. Obviously a single 5x10x1.8mm works better.. Be sure to join the magnets in the right position: the magnets tend to join itself in an opposite...

Hi all Does someone know the n100w data about APC slow flight props, expecially referred to 9x6, 10x4.7, 10x7 and 11x7 props? The n100w for 10x4.7 in the...
Those values are measured with exactly 100W of *output* i.e. shaft mechanical power. If you are getting less rpm, your output power is not 100W. If on the...
Bonjour aux membres Je suis Français et je dois avouer que je peine, à tout comprendre quant à la construction, j'ai récupéré un stator comme conseillé...
You can find some informations on some french web site (i.e on my site wapics). Questions in french are not well apreciate on this list ;o) so you can send...
I know this is not an LRK (it's a wye configuration), but since it's got LRK potential (12 arm stator), I thought I'd pass it along. If it's too far off...

Hi Dave, I'm new to this forum, and have been reading it for past couple weeks. Thanks for the insite into your project. I think I have an old drive I'd like...
Well, I am planning on putting up a web page with pictures, etc. when I get the whole thing figured out. My goal is to accomplish an LRK conversion of the zip...

I'm not sure I understand you... Are you suggesting building a motor from scratch, rather than by starting with a zip motor? Wouldn't that be harder to do? ...
Dave, All of the prop adapters, yokes, and E-props I've seen are 8 mm. If the hole in the bell is already that size, could one of the standard setscrew-type...

Hi Mike, I made my first LRK from a Caviar stator. There are pictures of it in my photo album. Magnets I were using are only 4*4*1 mm. That makes it posible to...
Hello Mike and Anders I've just finished rewinding a Caviar drive as an LRK and it works !! I rewound with 25 turns of 0.4mm and used 5x5x1mm magnets from Mr. ...
