12V DC Motor Turbine by mattheus Dec 30, 2012

Description

This turbine done from 3 parts: turbine itself, that was used with some changes from thing http://www.thingiverse.com/thing:13188 and case that consists from bottom part with motor holder and top part that covers turbine. Even with small 12V DC Motor it works perfect and powerfull enough.

The impeller from thingiverse.com/thing:209797 will work for this design, It allows you to use a standard hobby motor with a 2.25mm shaft.
better off using a pelton wheel design in most cases for micro-hydro.

There is one here thingiverse.com/thing:16579
I used motor from Lexmar Ink-jet printer (it is one that move printing head left-right). You can find such motors in Lexmark Z25 and similar and 510 series. I also think that in many other series of printers by this company motors are the same (many times they just change design without any changes inside and sell as new model).

Instructions

Print turbine (file "Turbine 2.STL") with high quality and cover parts (files "Turbine Cover (Top).STL" and "Turbine Cover (Bottom).STL") with wall thickness 0.8 mm and normal or high quality. In top part of cover you'll need to remove thin wall inside that needed only to form flat surface on top without using support structures (you can easy see it, as it is 0.4 mm thin). You can cut it using usual paper knife for example. Assemble cover together using M3x9 (or M3x12) bolts and nuts. Turbine designed to be connected to motor adapter with single M4x30 bolt. I used 25-32 mm tension band to handle the motor inside bottom part of cover.

I also attached adapter for motor that I have in file "Motor Gear Connector (Sliced) - 2.STL". Print two parts and connect together with two M3x16 bolts and nuts, put inside single M4 nut to be used for turbine connection.

Turbine top cover has end that fit just fine 30 mm pipe adapter designed here: http://www.thingiverse.com/thing:39745 and was done to be used together with it (take some time to see how and where it can be used together with this adapter).

Note: In some .STL files you'll need to flip Y-Z planes to place details correct on printing table.

Use free for your needs! ;)

Hi beautiful design. By any chance do you have the part number for the motor or more detail on the shaft size, length, etc. that would be required to bolt the turbine up to a motor.

I wanna see somebody try and perfect something like this for small-scale hydroelectric power. Build a small dam in a creek bed and stick one of these in it, and on one side put a valve that gets opened by a float-"swtich". Hook the turbine to a 12V battery and presto!

Exactly what I was thinking!
You might improve efficiency and reduce post-processing time if you replace that thin wall by thin stator vanes pointing into the direction of flow. It will make much more noise too, so it could double as a siren

But turning back the water meter???.
What are you using this for?
Together with thingiverse.com/thing:39745 I use it to wind off the water meter (http://i53.fastpic.ru/big/2012/1231/fb/948f519c99c7de15b650d5945f510efb.jpg), but of course you can use it in any other application, couse it quate powerful for it's size.

Go Ferris Bueller! Just don't drop the jag!
Strange place, you uploaded the pictures to.. looks more like a porn page to me.. ;)
must be because its russian domain.. lol

can you use this turbine for water? since you hang it to a water meashure device on the pic..
i think the fan is actually a compressor for air isnt it?
Yes, it was done as compressor for air initially. Generally think you can use it for water also, if motor will be isolated enough from water flow.
