timing

What is motor timing for?

[microgoat]

More timing in a motor increases its power at high speed. It's really a non-issue with the motors we use, since we use high winds and low speeds anyway. So you'll want 0 degrees timing, or low timing on a brushless.

I thought it was when the spark plugs got fired???????????



I tried fooling with timing when I ran brushed motors. Couldn't tell much difference at all. Low timing on my outrunner does help the cogging. Power wise though,no mater what the timing is,it'll strip gears and bust 8mm stub axles on command.

You know Raptor, I am this close to picking up a 3025-08, but I don't have enough spare parts stocked up yet

ive wondered myself how much difference advancing or retarding the timing would make. i dont really see how it would make any at all.

It depends on whether we're talking brushed or brushless.

On a brushed motor, more timing in a crawler just kills your runtime and builds up heat. Easpecially if you run in reverse a lot.

Timing for brushless (specifically outrunners) helps with startup and eliminating cogging issues, especially with 2/3A packs. Again, timing is related to speed. The faster you run, the more timing you want. Since the Mamba speedos are calibrated for 2-pole motors, their default timing is pretty high for a 12-pole outrunner. The more poles you have, the less timing you need.

CAUTION: LARGE WORDS AHEAD!

The reason motors are timed in the first place is to let the armatures become saturated with electrons by the time it or the magnet is in place during the motor's rotation. Since saturation takes a set amount of time (electrons only move so fast, see studies by Einstein et al), altering the point at which it begins (aka timing) can change the point at which the motor produces maximum power.
