Motor timing
 

This is the first time I have been adjusting the motor timing through the ESC. I am trying to understand what it does. Besides the obvious. It comes set at 18.5 degrees. Last night I ran it at 22 degrees. I did not see much of a change?

Lets say, motor can is set to 0 degrees. ESC is at 18.5 degrees. If I change it to 22 degrees, will it have more torque or more speed? I have read that it can create a lot more heat. So before I let the magic smoke out, I would like to have a little bit to go on.

In simplistic terms, in a brushless motor you have an electromagnet pulling on a permanent magnet (the rotor) to make it turn. Timing is the point at which the electromagnet is energized in relation to the rotor position.

The further away the rotor is from the electromagnet, the more energy can be applied to the rotor and make it spin faster. But the further away it is, it has less strength and it's harder it is to pull the rotor, hence less torque.

Total timing is the combination of both motor and ESC timing. In general more timing increases RPMs but reduces torque. More timing increases heat.

3.5 degrees of timing is such a small change, that unless you had the motor on a dyno, you probably wouldn't notice.

Thank you for the explanation. Now what I could see in my head makes sense. Thought it was just like setting a distributor in the old cars.

Just wanted to see if I could see a change in how the setup felt, so I did not want to make a big change and let the magic smoke out. I am gong to try a few settings and see if I can "feel" a difference in how it runs.

I think it went from 8 degrees to 35 degrees. Will have to check that one I may start at the lowest and see how it runs and then work up to the stock settings.


Thanks.
