Sealing Phase Wires Exit

[hias9]

I plan to upgrade from 4mm2 to 6mm2 phase wires through the axle. Outside the motor I already use 8mm2 phase wires.
There is enough space to put three 6mm2 and six thin (maybe 0.2mm2) PTFE insulated wires through the channel in the axle.
Because I am using ferrofluid, I want to seal the wire exit.

What kind of silicone should I use? It should also flow into all the little areas between the wires.

The ferro fluid will stick the the magnets, and fill the air gap between the ststor and rotor.

You couldn't force it to go near the axle if you tried. That being said, any silicone sealant will work.

I am using more than the recommended 8ml Statorade so heat transfer is also good at high rpms. I don't care about a little increase in drag. While the motor is turning the ferrofluid gets splashed around. It also goes to the phase wire insulations and bearings outer ring.

i did a similar thing to my motor,firstly i used thin hydraulic oil,didnt seem to cause a lot of drag,tried sealing the wires with black rtv but found the oil capillaried up the wires,long story short i never did find a way to seal it 100%,then tried it with glycol antifreeze same issue tho.
