Re: building the BESC - 100V, 400A motor controller

I think if I take your question correctly UVW is tied to each hall sensor, yes.

Re: building the BESC - 100V, 400A motor controller

I just used the hall sensor that came off of the QS205 hub motor. Plugged right in, worked like a champ. I have used AS5047s for other projects and I was not aware they could be used for VESCs. That's good to know.

Re: building the BESC - 100V, 400A motor controller

Thank you, that's very helpful. And I dont have any new STM32F405RGT6s but I do have a few toasted boards. (Catastrophic shorts probably between heat sinks of FETs and ground) -- but they still seem to program and light up the LEDs. I could put the boards in toaster over and yank their CPU if you're...

Galp, have you tested 1.1? Just curious if you've built boards from those files.

Re: building the BESC - 100V, 400A motor controller

not sure that everything in place in his new gerber there are no element placements ?
that's correct. you can't be sure that the position of all components for the gerber files for 1.1 will match the positions for my files.

Re: building the BESC - 100V, 400A motor controller

So I used the 1.0 schematics for my order because Galp did not publish the kicad files for 1.1. I needed the kicad files to make the files for PCBA. I think you are asking about how to make the CPL files for jlcpcb, but I'm not sure about your exact question. If you need to make the CPL files for jl...

Re: VESC Regen Throttle Connection

One of the ebay pics shows a diagram for the connectors, and on the one labeled 3, it looks like there is an ADC2. ADC stands for "analog to digital converter", and is frequently used by the VESC community to refer to the throttle inputs. The description says something stupid about ADC but...

Re: building the BESC - 100V, 400A motor controller

yes that's interesting you mention that, when PCBway sent me the quote for parts, they increased the cost of the gate drivers by 400% -- so it's good to hear some independent validation for why.

Re: Has anyone gone faster? If yes than who and what was top speed?

I get 90 kmh on my bike. (See sig). I think it's been faster but that's about when I stop looking down at the speedometer and look straight at the road.

Re: building the BESC - 100V, 400A motor controller

The updated files that Galp supplied were very useful. One issue is, at least for now, is these are just gerbers. Users dont have his updated kicad files which are useful for making BOM and position files in the case were you interested in having your boards made by PCBA. So I'm uploading a zip file...

Re: building the BESC - 100V, 400A motor controller

Galp:
Version v1.1 is now up on my website. It has that stupid inverter removed and silkscreen fixed. Anyone ordering the PCBs should use the v1.1 gerbers.
have you tested this version? Just curious if you made this version of the board and ran them.

Re: Mongoose Blackcomb

Bottom line- oversize your vesc. By a lot.
Bingo.

My guess is you want something off the shelf -- and unfortunately I dont know much about the commercially available VESCs.

Hello people I was riding with my G2 and heard a pop, the bike stopped and I had to walk the bike home. When I opened up the controller I found some burnt parts , and burn marks .

erdogank -- did you add a nrf51822 module to the BESC G2, or are you using some other VESC that has this module?

.The tool calls out ebike throttles as ADC devices. The only reference on the specs sheet to ADC is port #1. So I'm going to connect the throttle to 5v, GND, and ADC1 and see if that works. Yah sorry this is unknown territory for me, I don't know how that specific ESC works. But connecting adc1 see...

Barncat, the following is advice from someone that has NOT used your version of the board -- so treat any advice as provisional. On the leftmost panel of VESC-tool there is a menu item for "Firmware" and it looks like that is where you can change the hardware version. But I think V6.0 is t...
