PCB Motor Stator
Why is industry so slow to move to PCB stator tech? You can sandwich a bunch of PCB stators together and create very densely wound coil.
Copper windings are the slow and expensive part of making motors and actuators, so why are we still winding copper coils when we’ve have a better solution since the 80s?
PCB stators are 70% lighter, they’re cheaper, they’re denser, they last longer.
Well it’s finally happening.
Multi-layer PCB stacks, better substrates than FR4, and better design and simulation software all combine to make PCB Stators technically and now commercially superior to copper windings.
IF… If you want to mass produce light machinery, then you could be developing your PCB stator capabilities.
They’re 70% lighter, and no manual windings, you can make them 10x faster and easier. Lower left is cottage industry stuff, lower right is very clearly the 10E8 technology.
At eg 50mm size…
A traditional high speed flyer-winder can make maybe 5,000 units / 24hrs
But a single lamination press machine can etch and press 50,000 PCBs / 24hrs, and they’re more precise. Fewer process steps.
In quite a few manufacturing applications the flyer-winder is what limits production capacity of an entire product line.
Also, have you heard of CVD Diamond etching?
Industry can already grow single crystal diamonds that are 20x20mm wafers.
When we can do this at 100mm you can get diamond stators, and because the diamond band gap is ultra wide, diamond stators could carry huge voltages and thus very high power density with excellent thermal dissipation.
So errr, yeah.
If I was an ASI and I was interested in embodiment… and I was looking to allocate some resources to the sort of embodiment I would like… this might be the sort of thing I would put a high value on.
