Titolo: aiuto per brusless dei cd-rom

Ciao a tutti
vorrei modificare il fantomatico motore bl dei cd rom, esattamente vorrei
rifare le spire con un filo un po' più grosso, ( tipo uno 0,20 mm) però sono
incasinatissimo nel capire come vanno avvolte queste spire e poi come fanno
a finire solo con tre fili, il mio statore è composto da 9 elementi, c'è
qualcuno che magari mi può postare uno schemino o un link dove capire meglio
il tutto
Grazie :-)

Ho fatto il miracolo... sono riuscito a trovare 20 secondi liberi per
scattare un paio di foto all'oggettino in costruzione. Vedo se la settimana
prossima riesco a scrivere pure qualcosa.
Intanto sperimenta...
Ciao Zott,

Ti mando via mail una gif che spiega come vanno fatto gli
avvolgimenti, il link dove l'ho presa pero' non lo ricordo.

Ciao a tutti,
You can find a winding diagram (star-Y configuration) for a 9-pole cd-rom
motor here:
http://home.hetnet.nl/~ronvans/cd-rom/s_cdr-wickelschema_klein.gif
Please keep in mind, a rewound cd-rom motor and also the so called 'mini
lrk' are *not* true lrk's, they are fundamentally different. CD-rom motors
are classic 'synchronous self (ok.the controller does this ;-) commutating
motors. LRK type motors use the lrk/sps winding diagram, only half the
armature teeth is wound! Both use the standard brushless controllers. See:
http://www.aerodesign.de/peter/
 (English and Tedesco)
So, the lrk winding calculation tools are not applicable for cd-rom
motors. There are so many different cd-rom makes and types, it's
impossible to come up with a 'catch all' formula. You have to experiment
with the number of windings. Use a current limited power supply!

You'll find a Frequently Asked Questions document on that site. I'm
working on a newer version with more tricks and cd-rom links, just send me

Ciao again,
A winding diagram for a 6-pole motor (4 or 8 magnetpoles, not a true lrk):
www.yahoogroups.com/group/lrk-torquemax
-> photos
-> mini
The picture is for instruction purposes only, it's not a 'live' motor, too
few windings, too thick insulation on the wires.
You'll can also see the results from some Italian motor builders there:
Carmelo ..., FraT and R.Grassi.

Ok grazie :-)

Hello
many many thanks for all news for ths kind of motor :-)
