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

the controller was powered off,rotating motor was easy. You are lucky that the motor stops after releasing the throttle stick :). In my case (9-fet hailong-integrated controller) when you release the throttle (without pressing the brake lever), the motor never stops completely and rotates at a spee...

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

It's a mecanical problem, you can try to increase/decrease the tension of the spokes, but that might just shift the resonance range... No, this is not a "mechanical" problem, it is absolutely exactly a software problem. Or, perhaps, hardware problems (signal filtering, interference) of the KT contr...

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

Is it worth to try OSEC with KT36-ZWSRT (KTE-6S5-A) + LCD5 + MXUS XF08 rear geared wheel? Will it work? What about frame vibrations / resonances when using a rear geared motor with an original firmware? I tried the rear engines Mxus XF15R (Gear 50, 1:5 reduction rate), XF08 (1:4.4), as well as Bafa...

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

I have an S06S flashed with this firmware, and when I turn on the kit, the motor starts going at a moderate speed and doesn't stop until it's turned off again. I finished my experiments with the firmware because of the behavior of the thumb throttle that does not suit me, as I wrote above, and retu...

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

on the road when i turn the throttle to the end,the motor may take a 3-4 seconds and increase slowly to the max speed,not a quick response.do you? No, throttle "reaction rate" of this firmware is quite acceptable, although it is worse than the stock one. I talked about the throttle control mode. IM...

Re: OpenSource firmware BMSBattery Sxxx/Kuteng controllers S

Today I added a disgusting, stupid code (my C # knowledge is close to zero) in main.c to protect against an emergency - when the gas knob is accidentally pressed when the controller is turned on, or the hall sensor in the gas knob burned (4.3-5V on the control pin in this case) main.c display_init()...

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

So it should still be speed throttle, not torque? The throttle controls the current (= torque), that's the "normal" behaviour of every throttle in any motorcycle or car. Xnyle has build in the option assist lvl affects throttle , with this you can reduce the max amps of full throttle for low speeds...

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

A question, how is the trottle response compeared to the standard fw? I think it is a bit slow on the kt fw. Almosty all “factory” firmware (including KT original fw) uses “speed (rpm) control”, and not “torque (current) control” for the throttle. That is, by shifting the knob on 2-3 mm, the motor ...

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

The question about "max current" values in the latest (C#ROME-B ) firmware versions. What method of calculation and document is true now? "new" configh.h (~sep. 2018 in Master branch) #define BATTERY_CURRENT_MAX_VALUE 150L #define PHASE_CURRENT_MAX_VALUE 300L https://opensourceebikefirmware.bitbucke...
