New motor renders are up! Right now, I'm literally budgeting my food money to fund this, so as soon as I save up enough, I'll start making the main parts. The new design is way more expensive than just printing plastic motors, but it's going to be worth it. U can also see my previous post with full explanation of this design
Y³ – New Motor Renders + Design Updates (axial flux edition)
Hey everyone! Y³ here with some new renders of the motor I've been working on.
But first – here's the previous motor actually spinning if you wanna see where this all started: https://youtu.be/mrGAKGPwXec?si=jHV50e3r7TD26NU0
This update covers a bunch of changes based on your feedback plus some stuff I wanted to experiment with myself.
The big switch – axial flux
I moved to an axial flux design. No dramatic reason, just wanted to try something different and see how it compares. My previous design had basically zero torque because I skipped ferromagnetic metals entirely – bad call in hindsight. So now I'm figuring out how much steel actually satisfies me in terms of output, and as a starting point I went full send and made the rotor out of one big solid steel disc.
Cores & testing
I'll be printing cores with different amounts of steel to compare results. In picture 3 you can see the current test config – 7 thin steel sheets stacked together. Trying to find the sweet spot.
The 20° tilt experiment
Also rotated all the magnets and coils 20 degrees off the center radius. Just an experiment, curious to see if it changes anything meaningful.
Heat situation (aka my printer situation)
Only have ABS to work with right now since I can't afford a new printer or composite filaments. Hoping ABS holds up thermally well enough – fingers crossed, we'll see.
My own bldc motor fully designed by me and printed on 3d printer, no rpm test yet, but some successful launches has been done. Next steps to add back iron, VESC, more voltage and other stuff with some better design. Some extraordinary ideas about next design would be appreciated!
