Hello, i just switched to foc mode after riding my electric skateboard in bldc mode for some time, and my torque reduced dramatically, is it normal for foc or did configure something wrong?
Thanks
I am very new to this exciting field but am being rather frustrated by being unable to connect to the third party VESC (412 firmware according to the markings on the PCB) and my laptop which is running Windows 7.
So far I have tried 3 different USB cables but I always get the same kind of response from the VESC Tool, ie ' No ports found' or, ' Could not auto connect. make sure USB cable plugged in and that the VESC is powered.' The laptop makes an unusual audible note which I guess reinforces the fact that it can't make a connection.
Hi
I am having trouble pairing the Trampa Wand with the Trampa BLE module. I have updated the firmware on both the Wand and the BLE using SWD. This seemed to work ok. Using the pairing instructions, when I go to the pairing screen and turn on the Wand it just times out.
Hi all,
Looking through the VESC schematics and was wandering why the phase current signal has a switchable RC filter?
One being around 10kHz low pass (presumably to remove switching noise, and the other about 60kHz to (presumably to smooth the sharp edges)?
I'd have thought you'd have a single filter or none at all?
For background info, I might want to use the architecture and software for my own controller in the future.
Thanks ☺

I see the term low inductance being thrown around here and in the industry. What value of inductance is considered low?
Also I saw that the current filter being switched in and out by the VESC 6 plus is clamied to help with low inductance motor control. At what level of inductance does this current filter make a sigifiy difference?
I have a go kart that is powered by a Vesc. The only problem is that I only have forward and brake and no reverse. Is there a mode or a way to get all 3 at the same time with ppm control. I would like it to be like how brushless rc cars are. What I mean by this is that when the gas is pressed, the kart goes forward and when you press the brake, the kart brakes, but once you are stopped and you press the brake again, it acts as a reverse pedal so the kart goes backwards.
Hello,
Nice to me you all!
I have a vesc 6 but I have damaged the switch U11, could anyone provide me with a part number for it, please? Or point me to a BoM
Thank you
Hello,
I´m using a VESC 75/300 to try to control a 3kW BLDC motor from CPMotion. The issue is that I can´t pull more than 2.6kW (peak) and I don´t understand why.

Hi,
I'm new to electrical engineering and am currently in the process of modding a custom electric scooter I've built. But I need your help.
Hello Guys,
I'm new here, I am accually trying to design a custom VESC with 14V 400Amps.
I have to ask what software are you guys using for the layout and schematics design, I am quite familiar with Autodesk EAGLE,
but I am missing almost every component I need in the library and also can't find all of them for download,
has anyone any suggestions for better software for that purpose?
Thank you : )
