i started my journey here: Delfast Top3.0i / QS205 V3 hub motor with ND72450 controller.

i'm experiencing no issues with QS205 V3 hub motor with ND72450 controller syukanzaki. the motor can deliver 3000W (and more) and my battery is also 72V(48Ah).

today i got a notification within fardriver app (i use 2.2.4) that i need the new app. downloaded from fardriver and it is still 2.2.4 but works now. did the self-learning procedure and for some reason i have more power in the lower regions now. did not know what happened to the App but i like...

did some tests to get a better feeling for the sensor and the motor temperature. after 20 minutes of riding constantly uphill/downhill i reach 55° on the far-driver app. flir-image shows 36° on surface of hub motor. as you mentioned, it took some time for temperature to reach surface. what i...

guys you are 100% correct on every aspect so far. today i checked temperature while regenerative-breaking and the degrees went up pretty fast. regen-breaking (in my case -470W) results in more heat, than driving constantly with 1500W of power. we have 34°C today, so maybe this has an impact on...

found out the exact motor type now. it's a QS 205 V3. temperature sensor should be KTY83/122. motor should have 16 pole pairs. found some useful information here -> http://www.siaecosys.com/upfile/202203/2022032841777345.pdf what i noticed while testing the regenerative braking is, that...

i'm still learning how to setup the parameters correctly. thank's for all the information! in the meantime i looked for a GPS app that can run on my android-device (cat S62 pro). i tried this one -> GitHub - woheller69/gpscockpit: Android GPS dashboard and head-up display i think i can reach...

i'm on this regenerative-braking-thing... i'm wondering how much breaking is possible with the QS205 bldc hub. when i drive down the hill and reach 50km/h the regerative breaking puts out -470W at the most. i've set the parameters on different rpm speeds to 100%. playing around with maximum back...

today i managed to get regenerative braking to work on my QS205 hub motor. it needs further improvements but for now i'm quite happy with the results. here are the actual parameters in farDriver App 2.2.4 for some reason 'EABS when brake release' did not work for me. i got no...

for the charger... i plan to use a zener diode in series with resistor to limit the voltage in case the charger goes crazy (this is called positive clamping circuit). this type of diode should work i think -> https://www.tme.eu/Document/1b6b0cbe4740a988d003793015c93864/nte5240a.pdf It is...

finally i bought a Fardriver NS72450 and it works :) i use v223 of FarDriverApp. got it from Alibaba where i bought the controller. https://www.alibaba.com/product-detail/Electric-Motorcycle-3000W-Programmable-Sinewave-FOC_1600171913422.html now i'm looking for information on my hub motor...

hi all! last year i got my new delfast top3.0i ebike. i use it in winter and few weeks in spring. then on a ordinary charging session the thing broke. smoke came out of motor controller and that was end of story. because i have full waranty i tried to get help from delfast support. did not work...
