Re: Bafang 850C color LCD -- Flexible OpenSource firmware

Making progress, hoping to hear good news by next week. I have another route to go if I don't get permission by then, but things appear to be working out. You are currently using the 850c system for yourself, correct? Any new previews of the display screen to show off? I am trying not to crack open...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi, I cannot use the motors torque arm to hold the motor in position , so maybe I can drill holes into the gear housing and fix the motor to frames chainguide mount (ISCG-05). I've got a full suspension frame , that's my only option. Cheers ! No need to even do that. Just let the motor housing rest...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi Knutsel. Thank you for your reply. Not what I was hoping to hear, as I've eyeing this motor for a while. The only thing I can compare it to is my BBS02 750w 48v and it is very heavy duty (like a motorbike). But I actually miss the "real" bicycle experience as I mostly use the throttle (it has no...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I have to be more precise. A short circuit occurred when the speed sensor cable was broken. For a moment the engine stopped and I saw the speed of 56kmh on the speedometer, even though I was almost still. Then I unplugged the connector and it all started again. So in fact a short circuit between th...

Just unplug your speed sensor the TSDZ2 works fine without it. The high reading is usually caused by a weak signal such as a badly aligned magnet. Same with brakes it works fine if they are not plugged in.
I can't unplug because everything is hardwired and well protected against water, etc.

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

Perhaps for that high currents the implementation of casainho with a pure I-fraction control in the fast loop is better. Yes, I remember to read in a few sources that current controller is done on PWM fast loop (with PI controllers but in our case we do not have processing power for that) and speed...

Thanks for the information. I really miss Real Time Clock, I love it on 850C as during the week I always run against the clock, when I go to shop, gym, etc. The thing is that we can't make firmware for many LCDs so we should choose the ones that will stay long on the market. SW102 seems that will be...

Re: New "TSDZ2 Torque Sensor Central Motor"

Use the OpenSource firmware where you can see the amps, configure the current ramp step, configure the motor max temperature power reducing and limit, etc. This is great info and confirms my thoughts. The TSDZ2 is a nice unit but doesn't give the impression that it is heavy duty and built for long t...

Re: New "TSDZ2 Torque Sensor Central Motor"

Exactly. But I don't know any riders other than racers going full on on a breakaway that want to spin at 100 to 120 RPM. So for e-bikers needing to go that high is due to their choice of gearing (but why?) ... or the constraints of the bike... for chainring size and rear gearing cluster... and havi...

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

I've looked at the svm table and I am wondering what tool is used to generate it? Also would it be more efficient to disable pwm on the low phase? There are several approaches how to calculate the SVPWM pattern. You can't switch off any channel as we are using center aligned PWM. Zero in the lookup...
