it just uses a bunch of amps and overdrives the phases to make an extra little but of RPM.
think 20% more amps for 10% more speed. Not accelerating faster this is for sure.

Would this mean if i have yet to reach my locked speed on rpm there is still a benifit?
Any updates on this?
No, Brian scared the he heck out of all of us

I havent updated my boards in a couple years, kept using field weakening…
super anecdotal, havent had any serious issues. Then again I havent really pushed my boards much the last couple years.

Who had this working on esk8?
Just upgrade your pack to a higher voltage

Or gearing?

well you would lose acceleration, but if you’re light enough, it should be fine
If I build a battery let’s say a 14s I’d have to replace my VESC, BMS and charger.
Sounds like it’s time for an upgrade

Yeah, but if you’re coming up from 12s may as well go to 16 or 18 while you’re at it. Seems like a lot of work for an extra 7.2 volts.

Did you ride it?
Just saw that you did it to all your boards.

Ive been running field weakening for a long time now with no problems but wondering how efficient it is on a typical 12 tooth outrunner. I imagine if youre constantly accelerating from 0 as quickly as you can you’d be better off with a lower kv motor and using field weakening than a high kv motor.

been running field weakening on my ebike for a couple months at this point it brought the throttle only top speed from 33mph to 40mph which is nice, but most importantly it removed the hard wall at max speed

“duty cycle current limit start” already does this

But that just drops your top speed even more

Nope, just limits torque at high speed.
