General discussion

Hi,

 I am a new guy , I just get a HW4.0 based board and try to test it .

what I found is  that speed  is different  using FOC mode and  BLDC mode .

BLDC motor :  400KV,  Power:25V.   MAX no-load speed should be 10000rpm @25V. (400 * 25 = 10000 rpm)

In BLDC mode  I got  9300rpm( it's not bad), but in FOC mode it just ony 8500 rpm,too slow ...

I think two modes(FOC,BLDC) could be different a little bit.  But  9300rpm : 8500rpm ,it's too slow to use FOC mode .

Hi guys

I'm doing some tests with the VESC 6 for rotational position and I need some help. Since most of my tests involve the motor rotating to an angle that I want through the VESC, is there a way to change the speed at which the motor travels to the angle other than changing the switching frequency?

Hi, my BLDC servo motor has both internal hall sensors and an incremental encoder (see info below)

I have Chibi studio set up on Windows. I am trying to figure out how to open the vesc project. Simply importing the entire repo folder results with a ton of template projects from the STM32 examples, but not the actual vesc.

Does anyone know how to simply load the vesc project in a new install of Chibi Studio?

Hello everyone,

I have a homemade VESC 6 (with some hardware difference) and I'm having trouble programing the MCU (STM32f405).

I would like to upload a bootloader so I can then update my VESC from VESC Tool. Can I upload the boatloader of VESC 6(from Benjamin's Github) or do I need to rebuild the bootlaoder with my hardware specs ?

Can someone also remind me how to uplaod a bootlaoder to the MCU ? I found multiple tutorials online but I don't know which to follow..

Thank you very much

Hi,

I have a vesc from the  "torque"  vesc from diyelectricskateboard dot com. I'm controlling the vesc over can and needed to add a custom packet, so I clone the vesc git repo, added my function, changed the following preprocessor define:

`#define HW_VERSION_410 // Also for 4.11 and 4.12`

And then did a `make`

Hello,

Hello,

Just getting started with the VESC. Working great!

I have configured an analog throttle on ADC1 and analog brake on ADC2.

The "issue" I'm seeing is that if the throttle is on the brake turns the throttle into a reverse variable brake. (Essentially acting like a brake button would).

I would like the brake on ADC2 to "cut" the throttle when the brake is activated and go into pure braking "mode".

Hello all! I've been building small motors for years, and I want to try my hand at a hybrid, which lead me here. I'm very mechanically-inclined, but I'm very new to circuitry and computer science. I would love to get your thoughts on any modifications I could make to the v4.12 schematic to help solve some of the potential heating issues.
