The Untold Truth About Brushless Motor Timing - Where to Start?

- Brushless motor timing for sensorless motor or sensored motors generally work the same once the motor is in sync with the ESC. The ESC typically uses a timing range to navigate the best timing for your motor under the conditions at that exact moment in time.
In this video we are going to dive in to the performance gains that we could see with a bump in timing and ultimately determine if it’s worth it.

Hi Ryan thank you for providing us with such good content for our hobby ! Could you make a video in the future about tuning motors on Motor analyzer like the Skyrc one for instance ?
Thanks for the comment. I don't really use an analyzer such as the one you suggested. I'm a believer of using the motor in the car and adjusting from there.
@RCexplained totally agreed. However I thought interesting to explain us the relation between timing and amp draw for instance.
Timing is all heat I prefer less timing on castles motor and tp to Ryan!
Right on!
I'm an rc drag enthusiast, for my 10th scale cars timing is the most important aspect of car setup besides tires. We set our own timing curves based on track conditions. On good days I used to run ungodly amounts of timing on my 2 pole motor, like 105-110° by 40,000 rpm, still some people who are braver than me go as high as 130°on 2 pole drag motors.
This year I made the switch to 4 pole and I have a bit of confusion that I hope you can clear up. From what I understand 60° of timing on a 4 Pole motor will offset you by an entire phase Which is sort of like
Firing the spark plug bottom dead center of the compression stroke in an internal combustion engine If I understand the The concept. Yet some people are running well in excess of 60° on their 4 poles without a massive drop off in performance or detrimental effects for the most part, Other than pulling 350+ Amps on a 2s system.
I'm assuming that at very high R. P. M. The slight bit of delay in dwell time between faze switching is what they're compensating for, But I could also be completely wrong on everything stated above.
I would very much appreciate any knowledge You could share on this, it's probably going to help a lot of people not blow up esc's and motors.
Drag racing is a whole different ballgame. I run more than 60 just in the esc. And 20 on the can.
Interesting….. I’ll have to check my timing on my infraction 6s and see what it’s set to
Hello love the videos very informative. I have a question I’m running a mini b with 69mm foams powered with a Hobbywing 16bl30 and Ezrun 2030 7800kv 12t 2 pole motor. 18/60 stock gearing. What should I set the timing at? The combo that the 2030 comes in has the 18a hobbywing esc were I have the 30a one. I do drag/speed runs only 2s. 16bl30 stock setting is 11.25 degrees and the 18a esc is higher at 15 degrees. Should I put it at 15 degrees like it comes with the combo esc or go higher since Im trying to get as much top end as possible. Any help would be greatly appreciated
Hello good content...i got my limitless with a 34 spur and 32 pinion what u think in speed ur smart about this
thanks for the comment. Select your gearing based on the setup. Motor, batteries, tires and gearing. I have a downloadable (description) spreadsheet on my patreon site that may help.
The manual on my RTR said low timing is low temp so that's what I did to all of them. Surprising to see how minor the difference is.
low timing is definitely the most efficient for most setups.
anecdotally TP motors, strong magnet motors, like LOW timing. If a motor is easier to turn by hand it will take better to higher timing without as much heat. Im a boat guy and I run WYE TP motors at 5 degrees, 10 degrees max. I run leopards at 10-15 degrees depending on heat and prop. Overall lower timing is the way to go except maybe for
Boats are fun and definitely the most difficult to build for speed. It sure takes a lot of power to go fast.
All my timing is done with the motor. The track i run at they use the blinky mode esc. I usually run between 5 to 5.5 amps no matter what the timing is.
Amps?
@@LyroLife yes I set the timing to draw 5 to 5.5 amps from the motor so I don't run the motor to hot
I have a question 🙋♂️, so I race a slash with a 4600kv sensorless motor. If I set the Timing to 0 will it still give me 4600kv? Because the esc stock comes set at like 30degrees.
Timing advance only increases kv.
@@RCexplained ok thanks
information because of the relatively lesser amount of inherent MA in an inrunner bldc, the use of an inrunner should be reserved for Geared applications. meaning, it is the opposite of smart to use an inrunner in a edf.
Not sure what you mean by MA
So playing around with timing isn’t worth it, yes? Ok thanks.
