Neodymium engine

thingiverse

This is a prototype neodymium engine, it has yet to be printed. There are several obvious modifications, but I began designing it with the intention of making it fully printable from the start. However, some bearings in the main axis would be essential components. All screws used are M12, easy to find and replace with 1/2" screws if needed. I have access to a large quantity of Ø4x5 neodymium magnets through my current job, where we used them extensively. I designed this engine based on their properties, although I'm unsure if it will work as intended. It was a fun project to explore the possibilities. EDIT 10/08/2017 I replaced the rotor supports with bi-part ones to accommodate ISO 15 bearings (10x26x8) in the main axis. Additionally, I designed an axis with a DIN-5465 (D14-d11) groove for drag and a non-standard cotter pin at the output end. I also made some adjustments to the dimensions, making the stator slightly larger than before. Currently, the magnets of the rotor and stator do not touch. I believe this design is now functional. I purchased bearings in sets of ten for approximately 6€ each, while the neodymium magnets cost around 15€ per hundred units. I estimate the total material cost to be around 500 grams, which translates to a budget of approximately 40€. I replaced the original STL file that I initially uploaded with a new one based on my revised .SLDPRT design, without modifying any of the existing names when saving.
