Can’t judge a motor from pictures or specs on the internet really. Larger motors from a european and large manufacturer, yes - but not chinese.
What can be done to the 6384s:
-Laminations are already thin and in our rpms they won’t matter too much.
-You could get higher torque capability with high saturation steel laminations like the cobolt alloy ones.
-To match this the coils need to be able to produce those fields (=higher current) for longer time without overheating so windings need a better copper fill factor, could be achieved with hand winding or even hairpin windings, that would be novel on a motor this size😄
-switch to stronger, n52 magnets for efoil use (but not for land use as n52s are too temp sensitive, any heat rise and they are less powerful than a normal magnet.)
I bet you could get 1.5-2x the short term output of the motor. Continuous not so much since thermal properties will be limiting and this is hard to solve in a motor this small.
