Brushless motor timing

[Mich. Maniac]

I have seen on some esc's it is possible to change motor timing. I was just wondering before I do some testing to see if there is a preference of setting to anyone or should I not mess with that feature?

well nevermind, I was reading ready watts tips and stated to leave at factory, sorry to waste space.

What does the timing option do?

[Mich. Maniac]

not too sure. according to reddy watts it just heats up controller, on brushed motor it increases rpm but does decrease power.

I emailed Castle Creations about the Baracuda 80 and 125 timing settings last October. They recommended to leave it at the factory default. It changes the range the timing works in not the actual degree and that timing changes with rpm and is constantly adjusting. It does not work the way you would first think. They said it should have been named in the settings as - hot, hotter and burn up.

I do not know about the new hydra controllers.

Regardless of Castle's flip comment, advancing a BL motor's timing can help to optimize it for certain amperage ranges. For most sport and mild race use, a low timing value is best because with most motors moderate amp draw does not require a lot of advance.

For maximum effort though, as in serious SAW racing, advancing the timing will make the motor put out more power at high amp draws. It will not be efficient at moderate or low amp draws and should only be used for maximum effort racing for short periods of time - well under a minute. The amount of advance required depends on the motor, some designs actually need more advance than others. Some designs need only a little, the high performance Neu D wind motors for example. The timing advance requirement has a lot to do with the number of poles and the impedence of the motor windings.

Bottom line is to use the lowest timing advance you can get away with for your intended amp draw without overheating the motor.
