View Full Version : Electric Motor Timing 101

Advancing / Increasing the timing moves the power band up, decreasing moves the power band down. If you run excessive timing on a short track, it will be flat or bog coming out of the corner, than start to take off...almost like a delayed reaction.

If you're not running enough timing on a larger tack, the motor will feel like it needs to shift gears...it will jump off the corner, then stop pulling before it reaches the other end of the straightaway.

So pretty much low timing for small track and acceleration (touring) and higher timing for larger track (maybe more suited to oval racing)

Same sort of thing for offroad.

Of course, if you have a motor dyno you can measure your timing.

what is single, double and tripple windings all about?

ie: is a 13 single faster or slower than a 13 double or 13 triple??

I believe singles are faster than doubles and tripples. The doubles, tripples and quads have the torque higher up in the rev range and are smoother than singles.

just put my new 15 Double in, tht thing rips rubber off the tyres, on new asphalt and cement, can cut highspeed drifts on stock rubber tyres, no tape, or drift rings.
