I wasted a day trying to figure this out so I figured I'd post what I learned:
In order to use a AS5047 encoder with the Flipsky Mini FSESC4.20 (or anything based on VESC 4.12), you need to remove the filters on the encoder inputs.

Hello,
When using a dual VESC setup (each VESC controlling one motor each- both motors have identical specs i.e. same model) do the VESCs talk to each other at all? What I am curious to know is whether the two identical motors will be rotating at exactly the same speed or will there be a difference?
Cheers,

I'd like to use a variable speed trigger for brushless dc motors from "omron". Its the type you see on BLDC equipped battery operated drills. https://www.components.omron.com/product-detail?partNumber=C3AW. The datasheet is not super informative. the trigger has 8 cables and a fwd and rev switch. some clues: I know at 2mm of trigger travel you have start voltage of .3v and full speed start voltage 4.8v at total travel or 8.5mm. The trigger is rated to 42vdc.
Hello o/
I got to the point of just guessing and changing values randomly (which is bad of course), so at this point it's better to share tha pain and see if someone have any new ideas.
Dear Forum members
Hi All,
Maybe this is a bit off topic,
After doing a lot of testing trying to figure out what exactly was causing roughness during transition from sensored to sensorless mode, I noticed that currents were not smooth in sensored mode and especially bad during sensorless transition.
There is a clear indication of deadtime distortion happening during transition to sensorless and, in fact, most of the time while running in sensored mode. Motor phase graph was showing bumps and troughs as well. As shown on the pictures below. Once past the transition, the currents and phase line become smooth.
Hi everyone,
This is a real newbie question but I was woundering is the VESC 6 MK/V would be appropriate for a motor such as NEU 1509/1.5y /F/fan 6.7 (https://www.espritmodel.com/neu-1509g-series-motors.aspx)
Thanks
So, to supplement my DIY Onewheel, I want to build a "siren" that increases in volume and pitch with increasing motor duty, being fairly quiet at 50% duty and absolutely banshee at 80% duty. I'd prefer to implement it outside the VESC because I don't really want to mess with the VESC software, I'd rather leave it 100% dedicated to motor control.
Two questions:
Hi all - I've spent weeks searching this topic - everyone explains what regen *is*, but nobody seems to explain or know *how it works*.
How would my VESC take the voltage from my motor, and then use this to charge up my 58.8volt pack? - especially given that when I am using my brakes, I'm going slower and slower - *way* slower than my motor KV, so my motor is never going to be making anywhere near enough voltage to charge that 58.8 pack with ?
