The author posted up all his design files and has extensive documentation and instructions.
(Note that most of the housing is 3D printed while you still need bearings, coil and magnets etc). But still very cool what is possible and opens endless customization opportunities.
- jacquesm 8y agoVery neat. I wonder how the small magnets are retained when the rotor is stationary. The big ones slide in but the small ones are just pushed into place. Once the whole thing is moving they get pushed out but when it isn't moving the stator will suck them in.
- eschutte2 8y agoI'm assembling this right now, and the stator doesn't pull them out - it seems like the magnets on either side help keep them in place.
- ur-whale 8y agoAmazing maker build. Just watching the video is sheer pleasure.
- solarkraft 8y agoThis is cool, but I'm quite concerned about efficiency. There are much smaller motors that can release 4 times the energy of this one.
