General discussion

Hi everyone,

First of all - I want to thank asll VESC community for such great project and forums, where I can find answer for most of questions.

I have a working VESC project based on Paltatech 150 kw project (https://vesc-project.com/node/144 ) I succesfully managed to achieve max power of 14 kW, however, the motor I am using is an aviation 30(and 60) kW BLDC motor and I need to go further. I am now debugging the power stage since I have DRV FAULT after the power rises above.

Hi all, I have a v4.12 HW vesc, and used that for half a year on a 8S diy e-skate, 2-3 years ago. then it has been off till now.

So I installed the new Vesc-Tool and found out the firmware was old (2.18) so blindly updated to 5.1 (without checking the HW version..)

The motor doesn't run anymore. and I have the FAULT_CODE_DRV every time i try to move it using arrow keys or trying the BLDC detection.

I am having problems getting bluetooth to work. I would love to see my speed (somehow do not find this in the vesc tool on linux. But I know it works on the android app.

The bluetooth module gets power (measured 3.3v) And it gets seen when scanning - but when connecting: it connects but then gives me this error:

Good day ,  i started a new project based on vesc board. Now i use a langfeite t8 , that Is a e-bike with two motors with 1300w each other. I buyed a ubox from spintend site and i think that this board Is a good prduct with 75 v and two different output for the two motors . Maybe i wrong somewhere with the configuration of motors, but there Is something that doesn t turn. As i Say the motors are inrunner type without hall sensore and from datasheet thet must give 1300w with countinuosu Power and 1800w with peak Power .

Hi All, 

I have been working on an electric snowboard project...

Having issues with startup torque, seems the motor is instantly saturating on load.

I was able to get it to work with a config a month ago but have since struggled to tune it. 

Hello,

i made a custom PCB following the VESC 6.4 schematic. But when i have to setup my motor (Flipsky 6354) it makes a little sound for 1/2 of a second and after returns the error:

Hi 

Can a VESC motor controller theoretical be a amplifier for a speaker ? 

Hi I'm hoping someone can give me a little information regarding running a setup with a 12s4p 21700 molicel charge only BMS...I'm not sure exactly what the dangers of running the lion pack without discharge BMS and since i'm using a VESC esc can I protect my battery through the esc in the vesc tool settings and if so PLEASE what settings do I need to focus on!

I build material for the car training. This material is used in developing countries and should be inexpensive and mostly available in the country. I am developing a concept to build externally excited synchronous, permanently excited synchronous and asynchronous motors based on 12V car alternators. The alternator is a separately excited synchronous machine. By exchanging the rotor the other two motors can be build. Thus, the usual electric motors in electric cars can be demonstrated in a practical way. So, now my problem: I have already experimented with the VESC.

Hi,

I have a few Flipsky VESC 4.20 module with 5.1 Firmware, but the PWM input is reading about 1800uS with a 1500uS pulse applied (Checked with scope).  Has anyone else experienced this? I've used tis same hardware before and not had an issue so I'm assuming its the 5.1 firmware, but can't figure out how to downgarade the firmware to 5.0 or lower in order to confirm this.

Cheers.
