    BESC - beefed up VESC motor controller for high power ebikes

    I would like a PCB as well if available. Really like the project and I would be happy to build one for my bike.

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    It sounds to me you are always testing with full throttle? When you say if you increase the batt current by 50 the coggng is back, are you testing with full throttle? Maybe its a good test to try a smooth slow application of the throttle so you don't actually hit the limit? Also did you lower...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    @sascha the settings are basically what the wiki says.. The max current is a bit high and goes >20A at max throttle, when the controller is rated at 17A peak.. If you experience push- pull, or other "instability" try lowering the undervoltage limit, raising the phase current limit, and...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    Ok, I read the document and although I didn't understand all of it it seems that all phases are centered around 50% duty cycle when the commanded duty is 0. Is there any good reason behind this? I actually tried changing this so that 0 duty is actually 0 duty on the phase and the controller...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    I wanted to have low current limit in the beginning so I set it to something very low then gradually increased it.. I didn't have to swap any wires, all colours match as with the original firmware. I think the app is really helpful so maybe you should try another bluetooth module or phone..

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    I have just tested the firmware yesterday and it works great! The app is also very usefull to get it up and running. I have the 18fet controller with an ebay 48v 1kw hub. I used the following settings: motor angle 215 current calibration 50 battery current 120 battery voltage cal 140 Might...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    I have tried to run my motor today - 48v 1000w DD off ebay. Used the stancecoke firmware off github and managed to compile and flash fine. Hall and phase wires confirmed to work fine with the stock firmware beforehand. Controller is 72v 3000w 18fet. The problem is it runs rough and takes a lot...

    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

    I am new to this but yesterday managed to compile the code with no issues except that I had to comment out the following lines from the makefile-windows: # @$(ENTF) *.asm # @$(ENTF) *.rel # @$(ENTF) *.lk # @$(ENTF) *.lst # @$(ENTF) *.rst # @$(ENTF) *.sym # @$(ENTF) *.cdb # @$(ENTF) *.map #...
