Effects of Motor Can Timing, ESC and Boost settings on motor performance. Visit the RC Crew Chief Website www.wrightdesign.rccrewchief.ca for more details. @RCCrewChief
Great to see someone understand what's the problem with our hobby grade brushless tech. 10 years of brushless stuff, WHY not every brushless combo has a timing map programmed by the manufacture?
Very good Video and Info. Interesting to see that there is in fact a difference in ESCs Blinky Mode Power Outputs. I noticed this when running a knock off Chinese ESC and was struggling, then swapping to a LRP ESC and noticed that i was going quicker. Too bad that it still seems to be in the developing companys mind what "Zero Boost" really means and its not the same at all.
I can take a stab at some things that you might be seeing from one esc to the next. commutation is an output. its the relationship of when the coil is fired. the more precisely it is triggered in the real world the better it will be. there is a frequency at which it triggers. the processor has a fixed frequency and the transistor has a fixed frequency. if both are at a very high frequency there is more resolution to the physical relationship of the rotor and coil. the same concepts apply to the sensors that are being read. you have hall effect sensors and sensor less measurements based on back emf. In general, the error or accuracy of the last coil firing hinders or helps the next pulse a 5% change in output is probably common.
I know guys set their motor timing that way but I don't so can't really comment. I use the dyno so I can see the performance over the entire RPM range and not just one point.
@@RCCrewChief Was looking at file 2 and 3, where peak power seemed to be and amp draw was 4.9 and 6.1 respectively. Therefore wondered if this was the sweet spot and good to set the timing to these amp draws in blinky.
From what I know motor + boost + turbo should be no more than 60 deg. I haven't run a class with boost for a long time so could be wrong. I'll be doing more testing and will post the results.
A perfect system would have a map for, lets say, for every 1000RPM increase, throttle input and given temperature. So you will get max performance and efficiency.
