General discussion

Hello, I wanted to ask how I open the speed to a speed of 60 km/h in the software when the battery is 48 volts

Hi, I have an Arduino board displaying data over UART using VescUart. I want to show the reverse button status (is it in forward or in reverse direction). I can't find that data in the VescUart "datatypes.h" file or in the Vesc "commands.c" file but I'm not sure exactly what to look for.

Hello guys,

just bought my first ever Vesc based esc's from maker-x,

I have installed them after a whole day worth of time wasting!!!

my question is,

when I try to change the motor amp draw setting for one motor and then hit write 

the other esc automatically writes the same settings for the other motor,

the second esc is paired via can-bus,

i am accessing my both esc's via bt module.

any idea guys how to write settings on each esc individually??

thanks.

Hi!

I am unsure about the right KV value for my application (custom eBike/Pedelec) and I started to wonder, how important it really is.

My understanding is that I need to align the KV value together with the battery voltage so that I can reach my maximum desired speed. (If the motor runs to slow, it wouldn't support the cyclist anymore of course.)

For simplicity and focus, let's keep gear/pulley ratio out of the way and assume direct drive.

Let's assume these values:

Hello everyone,

I am currently facing an issue with connecting VESC Express via TCP using the iOS VESC Tool app and would appreciate any advice or insights from the community.

Background:

I am using VESC Express and have successfully established a connection via direct WiFi TCP with the macOS VESC Tool. Everything works perfectly on my Mac, and I'm able to control and monitor my setup without any issues.

Hi all

Is it possible to run HFI (sensorless) with PPM in Duty Cycle without the motor constantly screaming in the stopped position?

Hello,

I am new to the topic of electric motors and controllers. For my project, I need to synchronize two propellers mounted on a rig both in terms of RPM and position. I received a recommendation to use VESC ESCs for this purpose. However, I have been struggling to even get the motors started, and at one point, one of the motors started producing a loud screeching noise.

I am trying to get HFI running.

Hardware: Flipsky 75200 Pro V2 ESC.  Flipsky 65121 brushless motor. 

Firmware 6.05, HW 75_300_R2. Stable release

Hello,

We are trying to run a PMSM motor on STR500, which was purchased recently, and are facing issues to make it work.

On the other hand, we have 75/300 vesc on which the motor works great!

Following are the issues faced on STR500:
1. During the  'Run Detection' it takes around 40 amps whereas the 75/300 takes only about 10 amperes.

2. For the same ERPM and supply voltage the motor when run on str500 takes 40 amperes whereas the same motor when run on 75/300 takes only 12 amperes.

Hello all,
I had a Dualtron Popular that has been stolen during my holidays and now, I'm looking for a new Scooter. BUT first of it, there is no one that I would be convinced about within my budget. Therefore I would check out, how it would look if I would assemble myself one. BUT the first issue is, that actually I don't have any clue about how to configure VESC and therefore I would see first, if such a project would be hopeless due to my missing knowledge. Or if it could be done and some help could be found.
