    They gave me passwords but I just get password error when I enter them.

    Ant BMS Setup Not Saving Anything

    Thanks very much for that, I am able to see all the settings but they still don't save. I saw a passwords section but don't know what the passwords are, I think I need those to save settings.

    Ant BMS Setup Not Saving Anything

    Hi everyone, I am having a lot of bother setting up my ant bms, it pairs fine and I can read the cell voltages in the app but it doesn't save any settings I put in even after I select save. They always stay at 0. How do I set the cell count and save the settings I put in? When I select read...

    My design will be similar but I am using a totally different set of components and layout. The mosfets will be heatsunk to the bottom of the aluminium box I am mounting this in so they will be bent back against the pcb. I have yet to design the board that goes on top, this is just a rough layout.

    Hi, Help with power stage layout and design would be good, if there's any flaws you might see. I am going to redesign this controller where the power stage, 12v, 5v and 3.3v power supplies are on the bottom board and the MCU will be on a separate board which plugs in on top. That way I will...

    It's just the hub motor noise. So I can diagnose the regen issue, can I use a hc05 Bluetooth module with the vesc app?

    So here is my first road test. It works perfectly apart from the regen cutting out for about a second before coming back on again. This only happens during hard regen braking. The motor sometimes doesn't start properly but I think that is because of my loose axles. https://youtu.be/EgfNWWEtfNQ

    Controller Case Manufacturer Needed

    I was wondering if there are any companies who would sell me empty controller cases like the ones found on the kt 12 fet controllers for example?

    Thanks, did that, run a test and no squealing at all. Motor runs silently and smoothly so will need to do a road test soon.

    I have built the second prototype now with the suggested inprovements. I flashed it with the bldc master branch and downloaded the vesc tool from the vesc website but I am getting an error that the vesc has newer firmware than the vesc tool and the vesc has test firmware which isn't a safe...

    How does this look? I managed to fit everything in.

    So if I don't include C1 and R3, what will stop the high side mosfets from ringing?

    If you don't have a need for the board, then I will pay your return postage to me. Is this what I should start with? Hope I understood your suggestions properly.

    Wow, never expected it to be that easy to find what the issue was. It seems to be partly a layout and mostly a component selection issue. Agreed, ringing looks horrible and must be sorted. I hope we can work out what mosfets are best for this design as well as work out a snubber. I take it the...

    Is there any way I can find the KV of the motor? I also attached a scope to all three phases and I am getting PWM across all of them. Maybe I can try openloop mode if there is any way to use it like a vfd where I can adjust voltage and frequency?

    Do I find the number of pole pairs by applying a current to two of the phases and counting how many positions the motor settles in when I turn it by hand?

    How can I find the correct value? I did a test of the voltage across the bootstrap capacitors on the gate drivers and they all measured 12v as expected.

    I used the latest vesc tool and firmware build today but still having the same squealing motor problem. https://www.youtube.com/watch?v=XFHZRZ2NVrQ It appears to measure the resistance and inductance without issue but the flux linkage measurement just gives the squealing noise. When trying to...

    I managed to get the vesc tool to run, I downloaded it from the vesc forum again just in case it had been updated. When I connected to the vesc, I did get an error saying unable to deserialise app or motor configuration, so the beta firmware I flashed must have had some updates done to it in the...

    I managed to get the firmware downloaded and compiled but my old laptop won't run the vesc tool because of something to do with opengl. Maybe the android app will work, I assume I can just use the android app with an HC05 bluetooth module connected to the serial on the vesc? A feature I would...

    this all looks very promising! I tried to download the firmware but the link just contains the three vesc tools for windows, linux and android. Can you please give the link to the 5.03 firmware?

    Is the faulty board the exact same design as the working boards? Potentially there's an issue with one of the m74vhc1gt66 analogue switch chips?

    It might be a faulty pcb trace or maybe the MCU has a fault.
