Kinda OT - Brushless question

[AndyCold]

This must be the best place to ask, as all the brushless experts are here...

I've got a brushless question, I'm playing with a DIY project... That would be greatly improved by brushless technology (at least I think) But my knowledge of brushless technology is limited - figure I should ask the experts. Included a picture of a "current" version (appears to be run via a dc motor and magnets much like a laboratory magnetic stirer). I'd like the exterior to be much smaller - which is where the brushless comes in)

Basically what I want to do is to build the brushless motor to operate "through" a pane of glass. Mount the stator to the outside, then run the magnets to the inside... (would be driving an off the shelf 1.25" boat prop)

Basically my question becomes, can I do this with current cdrom-esque brushless designs? Or do I need to get custom? Obviously magnets would need to be considerably stronger, but is there a way to work around the stator ends not pointing directly at the magnets?

Thanks in advance,

Andy

If you look at the drive motor for a floppy disk, thats essentially what you're trying to do.

There is a kind of brushless motor where the stator is made from conventional coils of wire mounted in a circle with their ends facing in one direction. The rotator is a flat plate with permanent magnets mounted to it's face, this system could probably be made to work through a thin sheet of glass. It would also probably be easier to make than re-winding a CDROM motor.

Figured there was probably something out there that would work - any idea what it's used in? I'm guessing it'll likely be easier to find a source that uses one, than to try to buy the individual component...

FWIW - just finished ripping apart a LG, panasonic and fujitsu floppy drives - all seemed to be 'standard' cdrom configuration (although they were close to 2" dia)
