ambient was ~22C.
motor got up to 100C on the way home, but cooled down to 82C before i set up the camera and timer. i've edited it here to show the temp per minute. 27 degrees over 27 minutes, cools faster at first and slower at the end.
anecdotally, the motor cools down nice and quick when it's cooler out. on hot days, it doesn't cool down as fast.
it cools down nicely when the motors spinning and drawing < 1.5kw though i'll need to demonstrate this somehow.
it heats up very quickly (up to and over 100c) when bogged down in sand or up steep hill drawing 4kw.
i'd be happy to run more tests if you want. just let me know.
my questions are:
- an oil cooled motor is not necessarily a more efficient or powerful one, is it? it's just overheats less, right?
- how would it respond if i threw say, 2x the current at it?
here's a pic of how i sealed the wire slot, btw:
and added jbweld over the hall wires before fastening them down:
