alien will not deliver it waterproofed, maybe they can do it.
As a first step i discussed a modificated 6384 motor, here are the specs:
6384 Motor with following changes:
Do not glue the stator iron to the aluminium hub.
Do not mount flexible cables to phase wires, just let the phase wires around 10cm long. Mount plugs there if you need it for testing. I do not need them.
Do not mount any sensor, sensor cables. Instead prolong the iron core by 4mm.
Adapt the winding: RPM/V shall be 100. 100kv.
Leave space between the windings like you use to do with the 6384 130kv. It is needed for cooling.
End of spec.
This will make it much easier to waterproof the motor and get the best performance. The motor shall be available per backorder end of this week, so typically you can receive it in 8 weeks. Lets see.
You need epoxy of two qualities, i used these: “Gießharz Wasserklar” with can-time 4-5hours for the stator using vacuum and a “normal” one with 20-60 minute can- time for the rotor, both from R&G.
To provide the vacuum i use a fridge compressor, apply vacuum for 10 minutes, than release, do it over until there are no air bubbles visible. You should have some experience with epoxy, its not a good idea to do it with such nice motor for the first time.
With the new motor you have disassembled parts, so it should be easier to handle and also the phase wire to other cables interfacing is much easier. Latter one i could not solve perfectly with normal motors.
If we figure out, how it is done with good repeatability we could try to get it done in the fabb. But it will be costly, as it is time consuming.
