Boost efficiency with settings?

Other than put in the bldc and foc test results and change the motor and battery amp limits I do nothing.

Re: Torque increase

On my board it has less power in foc and less speed given the same amp settings.

Re: Field Weakening

Pf26 can u give an example of how inefficient it is to run a higher kv and is it an increase of heat in the motor or just the controller? I have a 90kv motor and would like the motor to stay as cool as possible and also have the option to hit higher speed.

Re: Max motor amps

Thank you I'll get logging today!

Begs another question: how can you have 200 amps in the motor and no inductance and motion.

Re: Max motor amps

Maybe I'm not loading the motor enough to hit the 200 motor amps? Is it measuring current going to or coming from the motor?

Max motor amps

ive been riding at 200 motor amp limi and 48 battery amp limit for a while and the performance is a huge improvement with low speed power and much less cogging. Do I only have to worry about heat, just as with the battery amp limit, or are other dangers possible with the high motor amp limit? I hear...

Re: 14S VESC ?

I'll bring it down to 165 which is seemingly the limit then I guess but if it truly can't measure the current why haven't I blown up? maybe the 200 amp currrent is smoothed out to a lower current by the time it makes it to the sensors? the 200 is the best performance I've had and without getting the...

Re: 14S VESC ?

Been running at 45 battery amps and 200 motor amps happily. Is there a risk doing this? I'd heard there was some loss of over current protection or something. Running a single hub motor with 12s foc. My other confusing question before..is it less efficient to run with a high voltage battery that giv...

Re: Vesc lvc and braking downhill

How can a circuit be made so current flows in the vesc and lights come on with no battery, yet if the full current were to flow it would destroy the vesc?
The difference between what could be generated and what is...how is that happening?

Re: Vesc lvc and braking downhill

everyone so far has been saying theres no power being created?

just trying to find out how it works. it creates power but how is the amount produced limited or determined?
