Nice to finally see Novak with new technology. Now, enough with the 540A rating. You guys should be the leader and start educating people. Do this, people like datasheet spec and there's a rating there which you can follow. Lets say you have 6 FETs per phase in a H bridge configuration that means 3 FETs should be calculated to get a AMP rating. Now if the FETs you're using has a Continuous Drain Current (TA) (ST Micro don't seem to use it), but lets use the 38A rating of the stk38n3llh5, that would give you a 114A rating and we all know the ESC can't dissipate that much heat. Use that as the maximum continuous burst, meaning it'll give that AMP rating everything one slams on the throttle. If it's marketing for the uneducated cool, but I really like honest looking specs and that's why Tekin and Castle gets my money. There are worst out there so you're not alone. To be honest, I would basically like something that can do 40A+ average throughout a race than anything and incase the sensor plug comes off, I would like to keep on going in sensorless mode instead of doing nothing.
