Thanks for the education Aaron. Now I know fella for sure.

[@ShaneBarrera]

You sound familiar, excellent lesson

Отличный видеоматериал! Спасибо. Всё рассказано доступно и понятно. Есть, конечно, ошибки на изображениях, но не критично. Только сейчас узнал о 150-градусном методе коммутации. Любопытно его "пощупать". Интересно, где бы ещё почитать или посмотреть по поводу компенсации пульсаций тока на первых двух методах?..

Audio barely audible, but thank you anyway for the interesting explanation.

sfoc is the way to go, go hard or go home

Does Tesla use FOC?

[@EhsanHabib]

Yes

Hi i have bldc motor I need to control 100 RPM with 4% accuracy. My hall feedback will get updated every 25 ms(60 degree at 100 RPM speed). I need the correction less than 10 ms once. Any possible solutions. Please suggest

Can barely hear this... is TI trying to keep this a secret? Maybe I should get an Analog Devices amplifier to increase the volume.

low audio cant hear much

☠️☠️☠️ I've been experiencing extremely dangerous episodes of the motor not stopping as soon as I turn the throttle , related to high humidity conditions ! I think it's because the humidity increases conductivity of the hall sensors in the throttle . can you recommend a good throttle ? I think the manufacturers are going to have to make them water proof. I experienced the same issue with a different throttle , battery and controller. just using the bike after a rain storm is enough to cause the issue. We must have a throttle will a switch to cut power ! ☠️ Also stop using hot glue on the Hall sensors ! It melts were I live ! And make the throttle not Fall apart so easy , and they need to be made with softer grips or made to accept normal grip's.
