General discussion

Hello all, my name is Raphael from france 



i want know if its possible adapt the Vesc firmware for work on STM32F103C8T6 on Xiaomi M365 ESC, its very sheap ESC can work to more 60A without problem, and cost just 20$, this ESC have one half duplex UART and one Full Duplex UART port com available for use, have 3 chunt current one by phase motor with ADC amplifier, and have hall sensor port, and have 1 ADC for voltage input and 3 other adc connect on 3 phrase for initial start default test 

Hi Guys,

Does anyone know how the vesc calculator determines the amount of power drawn from the battery? What equations are used? P = IV, P = Tw, P = Fv? 

Any insight would help. It did not seem to be a linear relationship which was confusing me.

Thank you

Myself, @vadicus, @bgdwiepp, and @TechAUmNu have discussed some common observations on our hardware when using the VESC firmware. We observed several factors that affect the quality of motor detection and motor operation for FOC. I will do my best to summarize our findings here.

Hi Guys - Ive been reading a fair bit on this site and looking at some of the projects that are ongoing. Looks like a great open source project with a big following!

I have an interest in developing hardware predominantly and would like to get a prototyping setup in place to have a go with the software and PC based tool to see what is possible before going all out on a design.

Hi i have 4 vesc' s 4.12.  just seeing if someone in Australia hopfully in Sydney could fix them for me?  One wont connect to usb when plugged in comes up with " The last usb device you connected to this computer malfunctioned and windows does not recognize it" windows 10. One i shorted the "CAN" and the stm32 chip is toasted the other one is blown from over erpm with only the blue led on and getting hot have 2 like this.

If anyone could help me out that would be great or walk me through the usb issue one as that still works just can't change the settings 

Hi,

I have a FSESC 4.12, and a Bafang 8fun geared hub motor, and when i do the motor configuration and control it with my keyboard it oscillate at the end of the RPM, and when i change the KP of the controller it stop doing that(there is always a some vibration). But when i set the app and throttle config, the control whit the keyboard it ll make noise(ti,ta, tac) without rotating.

I have a video this may explain more.

Hi,

I bought few months ago two VESC from DIYELECTRIC SKATEBOARD, in order to configure my own electric loangboard. I accomplished almost everything regarding the assembly part and I also managed to configure it using the free version of the software.

Now I am interested to know if there is any possibility to record somehow the evolution over time?? More than that I want to know if some parameters could be exported and how can I do this??

I am now working on VESC, and I have V6.6 Flipsky,and 190kv motor. I am trying to use one motor to control the steering, so I use a AS5047p encoder to control the angle. It passed all the detection and works good(can read the position accurately when I turn the motor by HAND). But now I face a problem is that when I give the angle which in the bottom of VESC tool, the motor just slip and judder.

Hello, I am trying to build a system like on metr where I can push a motorconfig profile to the vesc so I can change things like the max speed and current settings on the fly using my remote.

I have tried to adapt a library from basti30 (who added mcconf get/set features to RollinGeckos lib) but I can't get this to work. 

I am trying to understand the max rpm limitation. I previously thought that the theoretical max speed would be calculated by Kv * battery voltage. But in any case the real max speed at no load is a half of expected.

I use a vesc Hw: 4.1, Fw 3.58 at 8,4V with a Hacker A40-12S bldc (8Pols, 1350Kv). If i understood right the theoretical max. rpm is 8,4V*1350Kv=11340 RPM. I would expect the real no load rpm with 90-95% of the theoretical max. speed but i get 50%. 50% i get also with other motors and esc's ... so I guess I didn't understand something.
