Looking for short electric motor

How powerful does it need to be? The AXI 2212 series are about that size and they are more powerful than the average speed 400 motor.

Try looking in the model railway/railroad world. There should be plenty of motors like you describe.

will give you some idea of what is available. Click on the "Motors and Gearboxes" link.

The Mashima MH1624 looks suitable if you are prepared to remove the flywheel shaft.

The Mabuchi "mini/baby" motors have been available for years out of Japan. They start/stop with a flick of a finger so they're real handy for aircraft props. Available from hlj.com the last time I looked. hth The Keeper

Thanks, Paul, Exactly what I was looking for.

Don't you love the newsgroups?

Are not most "outrunner" motors really short, compared to "other" motor

That's what I thought - an outrunner, but then you have to go brushless controller which are more $, although they are coming down fast.

I wonder what outrunner motors were designed for in the first place? Industrial robotics? The seem to be proliferating like made in the hobby market. I wonder what the cost to manufacture comparison is?

Red S.

Some are, some aren't. I know that most I have seen have larger core winds and are fairly short. I have seen others that are fairly long.

Somewhere I got the impression they were originally designed for CD drives.

True, but the sizes we have available now belay the fact that they were just for CD drives. The hobby is not big enough to drive the development of the sizes we have available now . . . . or the AMA has greatly underestimated the electric flight opportunity. :-)

You probably want an outrunner then. They are large diameter, but short.

You can make our won from CD-ROM drives.

Contrillers are not cheap tho.

go to

and check out power systems discussion group.

Goedendag Red and all,

A list of RC outrunner manufacturers (kits too), over 65 by now:

Actually, the controllers have come down significantly in price recently. For example, the new Castle Creations Thunderbird-9 is less than $30.
