I guess this is a little off topic... I appologize! I've been looking all over the globe for the manufacturer of Depron Foam Sheeting. I thin my biggest...
Unless you want a shipping container full, there's no reason to be buying from the manufacturer. They are in the Netherlands. http://www.depron.nl/ Rick....
... In the US, there's also Depron USA (http://www.depronusa.com/) located in the state of Washington. Tom Hoopes (oakley@...) [Non-text portions of...
Thanks Rick! If anyone is looking for me, I'll be at Babel-Fish <grin>. Mark ... From: "Rick Page" <rick-page@...> To: <lrk-torquemax@yahoogroups.com> ...
Thanks Tom.. Actually, I'm trying to find the manufacturer. This link in the Netherlands might just be it. Mark ... From: "Tom Hoopes" <oakley@...> ...
Mark, Dont go looking and asking around for "depron". Go to shops that sell wooden floors etc. They usually sell dampening material to put under floors. They...
Thanks Frank.... This is something I've not done yet. I thought the US had regulations that prohibited the use of "Depron", and used other types of foam for ...
Hi all, does anyone here know, if CD-ROM or Streamer Motors can be modified to another number of magnets in the rotor than the original 12? LRK can be 14 or 10...
Hi all, A cd-rom motor in a Piccolo helicopter: http://home.planet.nl/~verin037/modelling1.htm Met vriendelijke groet ;-) Ron van Sommeren near Nijmegen, the...
and another one just here :) http://mitglied.lycos.de/hestoeck/planes_cdrmaking.html I'm actually building one more small CD ROM motor following this website...
On Wed, 3 Dec 2003 00:18:31 +0100, Marcellus <elgringo@...> ... I've seen a picture once of a direct drive heli. It used a 5.25" floppy disc motor i...
Hi Friedhelm, A 9statorpole/12magnetpole motor has a ratio of 6:1 between the rotating magnetic field and the shaft (higher torque = Ki /lower rpm = Kv), a...
Just an update on those Ebay motors that John was selling. Man am I an idiot. I was having so many problems getting the 14 or 10 pole rotors to work I didn't...
I just took one of these drives apart, it has a 36mm x 4mm stator with 18 teeth. Should I rewind it on all teeth or just 9? What should be the magnet count? ...
Hi Pierre, if you rewind it on all teeth, using 24 magnets, it will result in a reduction ratio of magnetic field to mechanical rotor rotation of 12 to 1. Look...
Hello all, Steve Peterson here again. I had a computer crash and lost most of my threads. Can someone tell how to get back to see how a cdrom motor can be...
Hi Steve ... You can find a description in english and german how I built my motor on: http://goldeneye.ethz.ch/motoren/electric/cdrom/index_EN/ or ...
Hi Wolfgang, Thank you very much for your information. I will start work on my motor this afternoon and order the magnets tomorrow. Your help is appreciated...
Hi, For a brushless motor does the stator need to have "divisible by three" stator teeth? I have a 10 tooth stator I am wondering if it is possible to make a...
Hi Steve and all, I compiled cd-rom threads/tricks/sources in this thread: http://www.rc-unionen.dk/nytforum/topic.asp?TOPIC_ID=368 Met vriendelijke groet ;-)...
Hi Jamie and all, You're right Jamie, since e-flight ESC's are three-phase controllers, they can only work in combination with a three phase motor. Hence the ...
Hi Pierre, There has been a number of messages on this subject. Search for messages by "torquepoint" or "herbert kabi". Met vriendelijke groet ;-) Ron van...
Hi Ron! So this stator could be rewound as a "two phase" or (god forbid!) a 5 phase brushless motor (5 halfbridges for control I guess?). May I ask why most...
Hi Jamie & all, ... Correct. All you have to do is design a 5-phase controller ... ... I don't know. My guess: 3-phase does the job, more phases is too ...
