This comment got me thinking...and I think there may be more to this than we all realise.icherouveim wrote:I have 4T motor but I think it doesn't matter. This setting corrects the wrong position of the hall sensors so -11 seems to be too way off.
I'm not professional but my experience says that correct values should be somewhere between -3 +3.
My last motors were working very well somewhere close to 0 and when I was testing for example at -7 the motor was overheating too fast.
Auto-detect has always put my halls at -5 to -8, but I've never felt like that was actually correct. If you watch the Auto-detect process closely you can see that the way it's determining halls position is through a combination of halls angle and IND timing until it finds the value with the lowest amps draw.
You can do this manually easily enough and get the same result with much reduced halls angle. I tried it yesterday and managed to reduce my values from around -7 angle corr/ ~390 IND timing down to about -2.9 angle corr / 174 IND timing. The amps draw is the same, so is the top speed and it pulls just as hard under WOT. My PWR setting is unchanged at 0.88.
Time will tell if I still have the same overheating issues, but I'm hopeful.
