Re: code to change the motor amp limit

so that's the answer. the sensor can't sense that high? that's as good an answer you can come up with. instead of trying to belittle me how bout you have a decent answer. I rode many miles at 200 motor amps and am asking why it works and works well when it's said the sensor can't do it. no i still h...

code to change the motor amp limit

Anyone have it and could give a super simple explanation for the non-knowing of how to change it?

Anyone have a simple detailed explanation of the risks?

Pwm and inductance

Since a magnetic field colapses instantly with each disconnect of a circuit it makes sense that the coils would produce an extremely powerful torque ripple at the motor's pulse train frequency. Why doesn't this happen?

Is the motor amps a peak or an average?

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...
