Third Party Hardware

Hello Guys, 

i would like to introduce my VESC-Design, which i ve made for my bachelors thesis. Its called SpaceVESC because it is used in our lab for the control of reaction wheels on a CubeSat test bench. The main benefit of this design is, that the logic-pcb can easily detached from the power-pcb.  For our lab we want to use different power-modules in the future so we dont have to care about the logic part all the time. 

Here is the schematic, which is like the vesc6:

Hi,

Im using 3 phase IGBT module.BLDC is working fine, but foc have strange current shape.

Also motor resistance measurement is wrong.(10mOhm on vesc , 50mOhm on IGBT module)

why current looks like this ?

Hi!

I wanted to try out VESC for a sensorless application and designed this:

https://drive.google.com/drive/folders/1hw-gLj4nVc55NpdjuklHnP325pea2THB...

This uses TO220 Mosfets - 150V and 20A.

So I was trying to program my Flipsky Dual FSESC6.6, I was able to program the left side just fine but then when I tried to program the right side it first said that "too old firmware..." well ok I updated the right side firmware but during the update it disconnected from the Dual FSESC6.6 and when I tried to reconnect it (after the 10-15sec. it needs to install the update) ,it just said "invalid serial port: \\.\COM3" in the right down corner. I even tried this with two different computers and three different USB cables and still the same results..

Hey, 

We are working on a small project involving Flipsky ESC's programmed via VESC.

We just connected 2 different ESC's to the same motor and after connecting the 6 pin JST for hall-effect sensors (5v H1 H2 H3 0V) (Temperature not supported so left disconnected) we think it is bricked. We also plugged in 3 other wires (RX, ADC, -) to a stripboard with an Arduino on it. 

So ever since the last 2 versions of the vesc firmware, I've noticed that the very first fraction of braking actually accelerates the board forward. If I lift the wheels off the ground and try move my throttle just the tiniest bit backwards to brake, I can actually get my wheels to spin forwards, then of course further backwards is braking as normal. I can feel this when riding. It's a little disconcerting when your board accelerates for a brief moment before braking. Any idea whats causing this?

Hi 

I run a 4.12 ESC on a sensored 125 KV Motor (Turnigy D5035) with 10S Battery.

Whenever i go with max Speed for 50 sec. (Power usage < 1kW) it refuses service for 2  to 3 min.

After that it is again ready to run

The ESC is less than handwarm. The motor is approx 40 degree Celsius.

Payload is approx 25 kg weight on a rail-carriage.

Does anybody have a good idea how to resolve this deficiency?

Hi guys, 

I'm working on higher voltage ESC to replace my older 100V (500A) ebike controller as there is plans to change my 24s (a123 20ah Lifepo4) battery pack to 24s Li-ion battery pack. Project details so far:
