Normally the inside temperature would almost always be higher than the ambient temperature.

hias9 said:I have also sealed the phase cable ends with silicone to avoid that moisture comes inside that way.
The sidecovers are sealed with high temp silicone and also the wire channel through the axle is sealed with silicone from both sides.
I run the motor quite hot. Thermal foldback is not applied before 140 degrees celsius at the windings.
Highest I had so far was 160 degrees at the temperature sensor on the windings.
Stator has been rewinded with 200 degrees rated wire and all other components like hall sensors and insulations replaced with ones that are rated for the higher temperatures. Statorade + Cooling fins bring the temperature down quickly.
@Luke: Would you recommend adding a gore vent in this case?

Over 100C maybe, which should evaporate all water. :lol:
