I have ordered this VESC controller https://diyelectricskateboard.com/collections/featured-items/products/to... my Velinon 3500 motor could not be controlled at lower speed. I loaded this configuration on it: https://github.com/mit-racecar/hardware/blob/master/vesc/6.141_bldc_old_...

Hi 

I have problems get the VESC motor controller to drive the TP100 inrunner motor:

Hi there,

So in my application there is a lot of frequent and sudden direction changes. I use VESC 6.

Sometimes VESC gets stuck in one direction for some period of time, before changing direction (once direction change command arrives, it takes few seconds for VESC to follow). Also, red LED flashes 3 times often times (I suppose, over current?), but VESC keeps working.

I wonder if there are any settings I can tweak to make VESC work more reliably?

Thanks!

Hello,

I am currently designing robot which uses 4 BLDC motor controllers. I am currently designing power supply board. 

Are there advantages in safety and charging when using common ground between batteries over separated ground?

I will provide details if needed about my question.

Hello

While waiting on the A200S I decided to improve the heat capability on the 4.12 esc I'm using now.

I use it on a hub motor on a 20" rim @ 10s (3kW peak), so it's not surprising that I have problems with heat  2-3 full throttle pulls and I was at the 80°C limit..

Has someone managed to connect the VESC to a Jetson Xavier?

I was following this tutorial (https://www.jetsonhacks.com/2017/06/01/get-your-motor-running-vesc-jetso...) which is actually for the TX1/TX2. NVIDIA mentioned that CDC-ACM should work on the Xavier without installing this. However, when starting the BLDC tool I am not able to connect to the VESC. It's not even listed.

I was finally able to get communication from then VESC to my RPi

Hi, 

Im testing VESC 4.12 and have some odd behavior with heating, does the battery voltage affect heating of the mosfet?
I have tried supply 20V and 40V.On 40 volts it get much hotter.
Test was done with 0% duty cycle.(FOC)

Device is working normally, just wonder why the voltage affects the temperature, especially when the duty is 0% and there is no current or is very small.

Can someone explain why is that?

Thanks
