Hi there,
First of all, I've been using this ESC with a stock Turnigy 80-100 130kv motor. Ran lots and lots of km's fine without any trouble. It was nice weather yesterday so I decided to make a little trip. After about 20 kilometers the ESC made some funny beeping noises and I heard a 'pfffff'. I immediately disconnected the battery from the ESC. The ESC is a little black now; the ''magic smoke'' came out.
But now the strange part! Before it blew up, I accelerated hard (like I always do
) to top speed. At that point I didn't accelerate anymore, I let the bike roll out for about 5 seconds... So the bike was still rolling like 30km/h (18mph), I turned the throttle just a little and right at that point, the motor should normally sync (which it did for about .1 second), the ESC blew. So there was NO load at all on the ESC or the motor because I was still rolling at 30km/h. Somehow the ESC didn't like the sync part???
I always pedal at the start to let the motor and ESC sync, and it never gave problems. The motor and ESC are sensorless obviously.
Could anybody explain me WHY this happened? Cause there wasn't any load on motor or ESC. I'm running this system for about a year without problems. And now suddenly this :|
I apologize for my bad English. If anything isn't clear please ask.
