KU63 CONTROLLER PDF

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. You should Sign Up. KU63 controller circuit board connections. What makes a BLDC controller good or bad? 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.

I also documented the PWM signals including the dead time, please see here: The middle wire in the connector is ground where in my setup the middle wire is signal. By reverse engineering bits of that hoverboard controller I learned enough to be able to ask some of the right questions.

The SD pad between the 5v reds and the negative blacks is seperate, with just the white stub on it, so Cobtroller take that as the throttle signal return. I have not managed to get any response from the throttle at all. Working backward from where I wound up on Dalek Bob: You must also be right with the PAS and throttle signals being white instead of green.

This controller also has a 3 wire 3 speed connector on it in addition to the standard varying voltage connection. Bummed that my con is gone, I worked on other things KU63 controller circuit board connections. Some are more fancy them others, but they are still Speed controllers. When you pull that to ground, the CPU starts driving the motors backward. FOC starts with the separation of two basics things: Unfortunately though, none of the photos showed clearly where the wires were connected on the board, and the diagrams were all circuit diagrams, with no circuit board layouts.

This feature is only available when using our OpenSource firmware. New posts New media New media comments New profile posts Latest activity. E-bike health studies show physical fitness benefits Started by: It only took about 6 hours to trace out the majority of the circuitry; when I started wondering what the mystery circuitry was for seriously, there are pins on the CPU that have capacitors directly control,er ground and naught else — why?

Try Home on site go to solar bike scroll down to electronics you will see ku 63 click on it. Just leave PAS disconnected. From memory, the throttle signal wire is on the end, not the middle. Endless Sphere — Development version Keep pulsing faster and it spins up.

I can figure out some of them without opening mine. I know I can smooth the throttle to get a ramp of throttle acceleration however I would prefer the controller did that, like in case a jump in a bump and the motor will quick accelerate and provide high power to the wheel, make it dangerous.

In theory, the teensy contrloler be able to read the pulses from the sensors and interpret them to assess speed of each motor. But for now contoller as 6 steps the same as KU63, JUxx controllersjust like the original firmware does when starts the motor and run it at very low speeds, before commutate to sinewave.

KU63 Controller Case

If you like my work, please consider making a donation. When you pulse the power in to each coil, it forces the permanent magnets to move forward one partial rotation. I cotnroller the issue is a wrong dead time between high side mosfets and low side, that short circuit the motor windings or mosfets a bit and that will boost the voltage thanks also to the capacitors on the board but also asks more current from the power supply and will make the noise on the motor. Reverse Engineering: Brushless DC Motor Controller FOC starts with the separation of two basics things: But for now just as 6 steps the same as KU63, JUxx controllersjust kk63 the original firmware does when starts the motor and run it at very low speeds, before commutate to sinewave. I have an electric bike with an existing 36v w controller. Yesterday I spent significant time drawing out the schematic of this nameless controller. This image is not mine, but in my controller, the 3 speed connection is on the TXD and RXD connections which have nothing on them in this picture.

There are a couple places in the power system where this newer controller has obviously tried to improve reliability. But I did wander across a reverse engineered ku63 controllerwhich is certainly along the same lines. Home All times are UTC. I bought two brushed DC controllers by mistake. From the last entry, it only took 6 more wires — PWM and commutator control lines — to test whether or not I could make the motor move.

Yolkree I have some clues. Halfords Group to stock Brompton Started by: For sure looks a good controller for 22 bucks. Similar projects worth following. The inductivity of the coil drives the current backwards then.
