Welp, My Kindernay VII is finally broken. I did 30 mph in light uphill on my Bafang m620 with 3000W Innotrace controller, everything was fine and then all of a sudden quite loud inconsistent clicking sound with resistance spots. I was thinking something happened with the Bafang m620. But after...
Here is how you can connect VESC Express to VESC for Bafang controller.
Here is the parts list:
1) Some PHB 2.0mm crimping terminals (you need just one). Can be purchased as a part of a set here...
It reduces traffic on the roads. If they will start putting more regulations on ebikes it will increase the traffic on the roads, more traffic jams. You just push people around from one place to another.
I have finished reverse engineering of the controller! The files format is KiCAD. It has complete reverse engineered schematic and PCB with all the components and complete information about circuits and sensors including the BAFANG M620 UART motor sensors and wiring harnesses.
Here are the...
Guys, the reverse engineering of the Innotrace X1 controller is almost complete and almost ready for public release so anyone can order parts on JLCPCB or PCBWay for cheap and start tinkering with it to have nice smooth controllable 3500W power, using it to repair their controllers in case of...
I emailed them and here is the automatically generated response
I emailed on [email protected], will see if they will respond. Meanwhile the trail.camp is not English speaking website.
I am afraid to destroy it doing so because if another drive-train will fail Kindernay is the only option I have (besides the oil leaks it just works). Also depending on the ratchet mechanism grease actually can make it stop working or make it works worst or can cause shearing and destroying the...
I poured full 40mL bottle before and my Kindernay VII leaked. While I am OK with oil leaks in general I am not OK when oil leaks on the brake rotor and this is what happened on my Kindernay VII. I rode it like that a year virtually without the real brake (once oil touched the brakes you have no...
Recently started digging deeper into the motor and found the rotor bearing (the one close to the gear) is completely locked and the inner race sled on the shaft. I disassembled the rotor and found the locked bearing rubbed into the shaft mating surface and damaged it. I am not sure if the...
I made a cable for VESC Express. I do not know how those connectors on the VESC Express side are called (I do not remember where I found them) but the end on the Bafang connector side can be made out of these parts...
Alright, great news, I think I fixed it. Just soldered a new AD8418WBRMZ chip, and the shortage is gone. So it looks like it is going to work. Now I need to repair the motor shaft (the current one wobbles and can hit the rotary encoder again). I am planning to use the new 15 teeth rotor with new...
Found another shortage between 3.3v rail and ground. This time in the bottom board. I was thinking the rotary encoder board is bad and detached it but it turned out the phase "U" current sense amplifier AD8418WBRMZ has internal shortage between ground pin and 3.3v Vs pin. Placed order on new...
