It uses the 5% duty off time to determine the rotor position from the bemf so if you shorten it to 1% it may be more likely to lose track of the rotor.
Found this on youtube from Vitali.
It was for dual hub motor with enertion vescx 1.2 and he had no issues whilst riding
Min duty cycle option is only used in BLDC control, so no efect in foc as duty cycle depends on speed.
It does effect current measurement like you said, but only on low speed.
Also default min is 0.5% not 5%, but max min value is 10%, limited in fw.
Yes but default max is 95% which means default duty off is 5%, in other words 5% of the time the rotor position is being analyzed. Increasing the default max reduces the % time the controller uses to determine rotor position.
Imagine those roller coasters with accelerator pads on the track. Each accelerator thingy represents one pulse in the right direction. Now imagine one of them is spinning at full speed in the opposite way. You’d have roller coaster seat shaped ribs for a while after that.
Same with vesc because with only 3 wires and 6 pulse stages there’s like 5 wrong ones that can lock the motor up.
Just, test it on the bench, put load on, variate speed, but don’t ride it until you’re sure and don’t recommend it to others as safe. It’s only 4% more speed
someone in europe/canada should do this because they have free healthcare
Will someone please film a vesc during a battery disconnect test? Spin up a motor, switch off the battery. Will the mosfets explode from rectifying 100-120V bemf? That’s what I want to know.
you’re asking someone to intentionally break their vesc?
Give me a vesc and I’ll do it
use one of those 30$ flipsky ones
Link?
will try to find it again. they come up occaisionly for that price on aliexpress
send me one, i will do the test on bench
jk, no plz dont
Sheesh I paid full price for a fsesc4.12, would hate to buy 2 more for that price.
i aint paying
Ahh ok, mhh
That sounds like something I wanted to hear tbh even though I wouldnt try skating some fantasy changes of myself but for future bench testings I have a new approach for some playing around. Thank you.
any guinea pigs running this? about to and looking for advice.
Running it, but haven’t hit FW zone when riding yet.
