    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...

    A Small 6 fet Vesc 6 Design

    Hi everyone, I just wanted to share my progress on a new vesc based controller I am working on. It follows the vesc 6 high power design schematics almost exactly apart from it being 6 fet, using linear regulators for the 3.3 and 5v power supplies and omitting the nrf51822. The layout is nowhere...

    Flashing Firmware to New Vesc 6 and Other Issues

    Hi everyone, I am designing my own vesc based controller and have a few questions. I am designing it based on this https://vesc-project.com/sites/default/files/Benjamin%20Posts/vesc_75_300.pdf How do I I flash the firmware to the MCU using the st link? I am using the STM32F405RGT6. There will...

    Vesc Hard Limiting Top Speed

    I have been using a flipsky 4.20 esc based on vesc and it is an enormous improvement over the KT controller I was using as it has much stronger regen, ability to set throttle curves and response as well as automatic motor setup. I have it set up with ADC throttles, one for accelerating and one...

    Converting 8 hall sensor values to 6

    I have now moved on to vesc from the KT controller and wanted to give the kt controller away to a friend all set up and ready to go on a bike. I measured the hall angles in the vesc tool and was wondering how I convert them to the values needed in the osec configurator? This is what the vesc...

    Using blue osec app to set best hall angles

    Hi everyone, I was wondering how is the app used to find the best hall sensor angles? I had the app running and was turning the wheel slowly by hand but the angle pie thing doesn't look right as hall angle 2 is missing. The motor runs pretty smoothly and quietly but I would like to get the best...

    Adding hall sensors - Best positions?

    Hi everyone, today I got a BLDC motor out of a broken 36v cordless chainsaw and was wanting to add hall sensors to it so that I can test controllers properly. I was wondering what the best position for the sensors would be? I could epoxy them between the spaces between the windings (shown in...

    Regen Throttle does nothing and motor rotates slowly

    Hi everyone, I got the stancecoke firmware working on the KT controller I asked about in another thread It definitely is the SVP version and it has one phase current sensor. Before putting the new firmware on it, I tested the controller and it was able to spin the motor very fast, even faster...

    Will This KT Controller Work with the Stancecoke Firmware?

    Hi everyone, my KT controller arrived today but I am not sure if it's going to work with the open source software. It only has one phase current sensor and as far as I know, FOC needs two. I have found what could possibly be the programming port but I am not sure what the pinout is. I think it...

    Adding Hall Sensors to Induction Motor

    I have a 195v 300Hz 3 phase induction motor from a washing machine. I was surprised to find that when I connected it to the controller on my electric bike running on 48v, it would spin up very fast and then cut out. If I kept a load on the motor, it would keep spinning without stopping. I...

    Struggling with KU63 Controller

    Hello. I have an electric bike with an existing 36v 800w controller. I received a spare controller for it today. It is 36v 500w and internally it looks almost exactly like a KU63. The difference being that this one has two pink wires that can be joined. I am unsure what the pink wires do. My...
