Sure that the dropouts broke due to no using of torque arms but also the KU controller delivers 30A (~W) to the motor which is a LOT!!. I received a spare controller for it today. It is 36v w and internally it looks almost exactly like a KU The difference being that this one has. I have redesigned the KU63 motor controller from BMSbattery. Here is the circuit: Don’t use the image above, download the circuit high.

Reverse Engineering: Brushless DC Motor Controller
The motor doesn’t want to turn at all. I am being using the donations to buy needed resources for my developments.
I will post some detailed images when I get home from work. I’ll dismantle it all tomorrow and have a look to see if the solder blob is maybe shorting against the adjacent tags, Q and A3. I’m trying to figure out some of the external lead connections on what I believe is a KU63 controller.

All I get is one level, which I think is level 3. You should Sign Up.
KU63 controller circuit board connections. The mosfet drivers are called “inverter” and as on DC-DC converters, the inverter can boost the voltage make it much more bigger than input voltage. What makes a BLDC controller good or bad? Use this method to post photos post controler If we can’t figure it out between us, I’ll open it.
I need a reverse. All controllers don’t use the same connector placement. Government releases 2 year action plan to improve road safety Started by: Overall, the KU63 work was good enough to give me a head start.
Leave the three-speed connector disconnected. I’ve got it back together now and just tried it. No jumpers or wire cutting is necessary. Some are more fancy them others, but they are still Speed controllers. I have two of these: There are other places where they’ve clearly optimized for cost reducing part count, particularly around the throttle. I will use this firmware as a base for the EBike controllers.
Thinking about what has been posted on this forum before, I understand that the green wire back from the led controller panel gives 1, 2 or 3v back to switch the levels of PAS. Blue is return 36v from panel The white wire next to the black one is the speed limiter ground.
With the wire in place, you have to pedal before you can use the throttle. I run a little “W” Bafang with a 20A controller with a 12S LiPo battery which peaks conrroller around W and don’t have a problem even without a torque arm You can spend time researching on your own, which takes substantially longer; 3.
Struggling with KU63 Controller – Endless Sphere
It works the same if you cut that purple wire. It’s a KU65 not a KU I had found that web page with my Google search, and found it to be the most informative so far on the KU I didn’t used torque arms and I just had 30 seconds the bicycle with me and after the aluminium dropouts on the forque broke!! But the flip side of Dunning-Kruger is that it doesn’t take much knowledge in a subject to start to get a handhold on it.
So, some quick soldering in both and we can start testing The con is done and won’t be coming back, so I’ve left this one rotting in storage. The motor is a direct drive one: Q rear driving E-bike Hub Motor Voltage: I need this controller to work just with a throttle connection.
If the power is still too much, grind the remaining shunt thinner or put the second shunt in series with it, so you effectively get near 10A down from 40A. You do not have the required permissions to view the files attached to this post.
I have some clues.
