Small, Sensitive Lumia Motor

[mixedgas]

Geared down Maxon Motor
Unloaded, 1.2 volts = 1 turn in 15 seconds. .6 = volts = 1 turn in 50 seconds
Loaded with an actual wheel on, it will get slower but need quite a bit more voltage.

Easy to slow down with higher voltages, just add 470 ohm 1/2 watt metal film (or similar) resistor in series. Coil resistance is about 150 ohms.

Shaft diameter ~ .0730 inch, Overall length 1.91 inch, body diameter .66o inch. Shaft length 0.20 inch , shaft is on .135 inch mounting boss out of body. On bracket with holes on 1.125" spacing.

Three available, removed from working medical imaging machines, asking 15$ Each + reasonable shipping.

Due to recent confusion, I'll go with received PMs as the way to know who's on first. But do post here as well, and declare if you only want one, etc...

Nice price

I love the Maxon and Escap gearmotors - my preferred when they can be found.

and please let me know if you get your hands on some more

thanks!

Steve as you've sold out, I'm posting this.

If you have more, or if I'm in anyway treading on your toes, let me know and I'll remove the post.

Lanek, you could look at Maplin:

That's the large one, there are other sizes, Como appears to be the brand.

The model number vs speed is contained in the table as there are various models in each size and various speed options across the voltages.

Never used these, but happened across these today in the catalogue before seeing this post. I thus leave suitability to your judgement but thought I'd put them out there as a possible solution subject to suitability, if Steve doesn't have anymore.

thanks for the link Al.

Order Code: N01BQ seems to fit the bill rpm-wise, but the too high reduction ratio makes me sceptical about vibration and jumpiness in the movement.
Maybe someone has tried them
