We gonna get a better motor, better to build this thing, suited for our purposes. I put my requirements here to get your input.
So here is my specification:
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.
What is the sience behind?
Some space inside the motor is used for sensors we do not need. It can be used for iron core prolongation by 4mm which makes 54mm then. By this we gain some space for copper and iron and increase the powerdensity by 8% in the given volume, the weight is increased.
We want only 100kv. This means either stronger magnets and/or different winding. If it is only done by the winding, the current rating goes down. Too strong currents would overload the magnetic field and yield to higher power losses. On the other hand, with this knowledge, it is ok to make more windings with thinner diameter if they are cooled well. To ensure this, there has to be some space left between the winding packages on the full length for waterflow, which increases the resistance and powerlosses.
If you are searching for the highest possible power region with some given parameters you end up with some waterflow and some generalized averaged warming. I suggest high throughput, best possible cooling, from there you can optimize. The system is not going to crash because of overdimensioned cooling.
So if you see any improvements regarding the motor, tell it now.
