Same 190KV motors (lacroix inventory). Yeah they’re very effective space heaters. Sealed motor cans, kinda to be expected with that much copper. The 140kv version at HV is going to be interesting to test on.
They do seem to hold up okay but if you’re running fw5.1 you have to disable thermal throttling due to a median filtering bug in that version. I ran into that on my first test ride out the other day:
You can see the faults towards the end.
I feel like the physical robustness of these motors makes up for the extra heat they produce. My old ones are absolutely hammered but they still run great- just sound a bit too loud at this point from the bearings being a bit shot.
