I will not reflect on the IP topic any more, but it became obvious that I need to clarify my intentions.
After checking out some of the videos you guys posted, it became clear to me, that if I want to build an eFoil thruster, I will need a motor and an esc specifically designed for the application in order to do things right.
In this case I’m risking tens of thousands of Euros spent on a system, which might as well be useless, because I have no experience with the application. On the other hand, if you help with the specs., and I decide to have manufactured a couple of pieces (1-2) for my personal interest, after that it will be significantly cheaper to produce quantities of couple of tens per batch. (And sell it to you guys with minimal-to-no margin, after having the initial costs returned)
Hence the suggestion: First of all lets find out some specifications, like required RPM, torque, current, voltage, and geometries of a motor. It also requires the decision to be made: large prop or jet.
After this, I can get you some estimation on pricing, and approximately plus-minus 5% accurate details of such a motor. (@PowerGlider: Yes that means opensourcing the motor design) . When it is decided, that the motor is ok, I can have some protos made, and get them tested (maybe by some of you in europe), and we can start mass production.
At the end I see this as a win-win scenario, because we split the initial costs, and we all gain some optimised power source, yet we have the chance to do things, that never would be possible with a stock motor (like integrate the stator itself to the external housing of the thruster unit, or use a single, but replaceable shaft from the rotor to the prop…
