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

I do have Bafang motor with 6 magnets for speed reading. How to setup this properly so i can get real time speed read? Shall i select "external" speed sensor? How about defining six magnets? Appreciate any response. I think if you select 'External speed sensor' and then divide your wheel ...

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

Thank you soo much, @stancecoke!! That really helped me a lot. @geofft: Funny thing: I ended up with almost the default setting, as you recommended. :) '239' brought me down to minimum measured current (1.3A) .....thought I'd give stancecoke's wheel-in-the-air-current-measurement method a try, had ...

Re: Still some help needed -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to

Esp for the angle, I can go from 1 to 255 and I find multiple 'maxima' settings where the motor sounds smooth and fast running (all tested w/o load -> wheel in the air). However, at the fasted & smoothest setting (around a value of '15'), the current draw (as per BluOSEC App) goes unproportiona...

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

How does the torque from x4 branch work differently? I can't really find any documentation on it. I run the a torque sensor, so by the sound of things I could use it. The 'torque from x4' branch allows you to run both throttle and torque sensor together by connecting the throttle as normal and the ...

Hello guys, I'm new here. I compiled and flashed the firmware on a KT36/48SVPRD-HRD01 controller. I get no error at compiling (with proven setting: THR-PAS,KT36-48svpr,12s,26inch,Q128h + Diagnostics), Just a couple of things worth mentioning with those settings.

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

Well done! It sometimes takes a bit of patience and experiment to get it to run how you want, but it's worth the effort in the end.
Like you say the feel of a torquesensor bike is quite special, getting back on my BBS02 equipped bike just doesn't feel the same any more.... :(

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

Do you use the 6- or 9-fet controller? I'm using the 6-fet. One minor downside of the o/s firmware is that the controller runs a bit hotter than stock and doesn't like being enclosed in a saddlebag. The small size of the 6-fet means I can mount it under the rear rack, here it's hidden from sight bu...

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

I see you run the q128 as well. How much current (phase and batt) do you run in it? I'm using configurator values of 150/500 for battery and phase current max. These settings seem to draw around 800-900 watts max from the battery (measured with inline ammeter), seems about right for this motor. In ...

@stancecoke,

I've recently switched from Xnyle's 'x4throttle' branch to your 'Torque_from_X4' branch and glad to say all is now working very sweetly.

Sorry to put another request on you, but just wondered if you have any plans to add walk assist to the 'Torque_from_X4' branch? :roll:

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

Was it just a case of getting the phases correct to match the Kunteng? Yeah, it's just another motor. I'm currently using a motor angle of 246 but that may change over the coming days as I fine tune it. Hall sensors: Where the bafang controller had: Red, Black, Grey, White, Blue The s12s has: Red, ...
