verjetno ste o tej temi že pisali, sam jst nisem najdu.

tolko se govori o teh BK pogonih iz CD-ROMA, pa me zanima, kolk močno je to, in predvsem KAKO SE NAREDI?

:oops:

hvala LP

Komur pozornost ne pade na koncu bo zasledil tudi tale zanimiv link:

Lepo prikazano in preprosto razloženo je v večih stopnjah tako, kot je gospod napredoval v pridobivanju izkušenj, začenjši z:

http://www.solcon.nl/gjkool/brushlessE1.html

Koliko moči ven dobiš pa iz glave ne znam povedati. Znano mi je to, da se da lahko dva statorja ali celo več skupaj in s tem pridobi na moči, navoru, izkoristku ... jasno tudi na masi. Taki motorji so Nemci poimenovali "Doppelwhooper". Dvojni hamburger

Veliko debat najdeš na http://www.rcgroups.com, pa tudi na yahoo groups ZELO priporočam!

Najprej se vprasaj, ce se zadeva se sploh splaca. Saj so BK motorcki ze zelo poceni, vlozeno delo, da ga bos sam naredil pa je kar veliko!

Se vseeno pa moras kupiti dragi regler...

Po tej teoriji se nobenega modela ne izplača doma delat kajti Kitajčki so fuul poceni in dostikrat je gotov model za isto ceno kot bi bil sam materijal

Se strinjam popolnoma...

Dejansko se gres "rocno" delo samo, ce te pac to veseli in imas cas. Cenovno gledano pa ni racunice...

Če se je kdo že lotil izdelave brezkrtačnika iz CDroma ali ima teoretično znanje bi ga prosil da mi odgovori na naslednje vprašanje:

Zbral sem nekaj starih CDromov in ugotovil da imajo vglavnem dve velikosti statorjev na katerem je navitje. Nekateri imajo premer 24mm drugi pa cca 20mm, debelina pa je pri obeh enaka. Zanima me torej ali lahko dosežem enako moč če dva manjša postavim enega za drugim kot da žico navijem na enega velikega.
Cilj mi je namreč da bi naredil motor enake velikosti kot je Speed 400, tako da nebi bilo treba preurejeti nosilce pri avionih.

Ron, welcome to the forum!

Robi, če bi kaj prebiral tuje forume, bi Rona dobro poznal, saj ga je "povsod ogromno"! Če ti ni očitno, je Nizozemec.

Lokacija: near Nijmegen, the Netherlands

To be more specific, Druten near Nijmegen, near the German border. See the maps to our club airfield here (and pictures of our annual int. electric fly-in too):

I did a decent introduction of myself.

Včeraj smo se na Krtinskem modelarskem letališču dobili štirje zelo zagreti in malo podebatirali o motorčkih. Upam, da bom lahko kmalu pokazal slike motorjev "Made in Mengeš"

Z zelo zanimivo predelavo so se pokazali motorji iz trdih diskov, saj imajo 12 polen stator in kroglične ležaje.

2S1P Konion
Swing 1000 LiPo
MiM motor Mk I z originalnimi magneti
Güntherca

6 A, vlek 320 g.

:wink:

9 polni motorje bom poskušal previti, da bodo uporabni tudi v čolnih - Mini in če se bo izšlo tudi v avtih - 1:24

Zna bit zanimivo

Napisal/-a **mihah** » 07.09.2004, 22:19

Tole so pa akuji, primerni za experimentiranje s temi zadevami - mala letala, čolni in avti

Na sliki:
KOKAM 350HD 2S1P, 340 mAh, max 7A, masa paketa 21 g
E-TEC 700 2S1P, 700 mAh, max 5A, masa paketa 33 g

Za primerjavo s Konion 2S1P, 1100 mAh max 20 A (overdoze za CDROM motorčke), masa paketa 87 g.
