Electric Supercharger Version 1 - Page 2

Back to first Page

 

This project is about using an electric motor to power a supercharger, the design I have gone with is an axial fan blade turbocharger. On the previous page I built up the supercharger and 3D printed some fan blades. The stage I'm at now is finding the right design of blade that will provide at least 8 psi of boost, ideally 10 psi. I certainly intend to finish the project or pursue it to the best of my ability, it is not a question of whether it will work because in theory it would, my issue is the 3D printed quality of my blades. As a side line project I will also be modifying an existing turbo, first just an electric one and later a hybrid.

 

29 July 2017 - I came up with another design of blade, hopefully it should work. The area ratio of this design is 3.7 : 1 , if this design does not produce pressure then I may have to resort to a complete re-design of the blade housing.

I had quite a lot of issue with the 3D printing process, I used a material called PETG which has a lower melting temperature than the ABS. I chose PETG due to it's better layer adhesion but as you can see the result is not perfect.

So did it work? Well no, it decided to shatter, the blades must have opened out and caught against the blade housing.

30 July 2017 - I started the day with printing a new bearing housing in PETG, I had to orientate the blades to point in the opposite direction and I also reduced the area.

I printed a new impeller in ABS and I also made the blades thicker.

So did it work? No. It produced plenty of airflow and a small amount of pressure but nowhere near as much as I would like. I believe it would increase the power of an engine and it would be noticeable but for the amount of money I think it would be unreasonable.

Can I succeed with this project?, unless I can increase the speed of my motor to probably around 100,000rpm I guess not. So where does this project go from now, well this one has ended but I certainly have not given up on the idea of an electric supercharger. Check out my projects for further updates on the electric supercharger idea.
