General discussion

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.

Motor specifications:

• 48V
• Voltage range 36V– 56V
• 62.5A
• nominal power 3kW
• Peak power 5kW
• Holding torque 6.66Nm
• Peak torque14Nm
• rated RPM 4300

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 : )

Can I use the vesc tool on my raptor 2 to update the firmware and alter the settings 

I am running 3.5 turn QS Hub motor in 16 inch moto wheel and was wondering what would go wrong if I will have ves similar to 75/300 for it? 

Anyone tried yet? 

Would it be possible to run at 100-120 battery amps constant? 

Is it possible to use the WAND remote with other non-Trampa boards too, e.g. Evolve Carbon GTR?
