It never died, but it has been throttling current in mildly extreme hill climbing situations. It’s actually done amazingly well, considering how often I’ve overheated it. I was running it at 120A motor during the race, and it just couldn’t handle it. I’ve been running it at 85A recently and it’s still throttling under steep hill climb situations. I estimate its continuous current output at ~60A. That just isn’t enough to give me what I’m looking for. Plus, looks like starting up manufacturing of them again isn’t going to happen, with the current state of affairs with Enertion.
I’d like to run at least 80A continuous for hill climbing, etc. I’ll also be testing out a 80100 130 kV motor in the next round of prototypes. That motor can handle 148A, so I’d love a speed controller that can push that current. That would really bring the performance to a whole different level. Torque output would be 257% higher than with the 6380 170 kV motor in the current prototype.
