KU63 CONTROLLER PDF

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.

A little soldering and prying later, some minor repairs and re-seating the caps I pulled out, and Deleted member Guest Dec 29, BeforeI’d not worked with brushless DC motors. Which means focusing on the electronics. Controloer first pass just turns off the motors; the base still continues to roll.

There should be three: I’m not dexterous enough to flick the magnet rapidly past the controlker and turn the twist grip at the same time! And the pulse length is the amount of time that sensor stays active, so it’s inversely proportional to the speed. As you deduced, I think the brake must have been connected to SH, and that the two microswitches were then connected to the common 5v within the loom.

Sometimes they don’t do it on these KU series controllers, so it’s advisable to do it yourself, especially on the KU with 30 amps. How many wires should be connected?

Why yes, there is. I apologize for my bad english. I’ll dismantle it all tomorrow and have a look to see if the solder blob is maybe conhroller against the adjacent tags, Q and A3. I had to open it. So we bought a hoverboard, disassembled it, reverse engineered a little, and that’s when I learned about brushless controllers.

As you don’t have any speed restriction wires, you might find a software restriction! KU63 controller circuit board connections.

Feel the bump in the motor, see the output in the terminal. 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. Why would I want to write software to work around bugs in software? I’m very much obliged with your help on this. They’re no longer adhering to the board – par for the course with me desoldering. They’re beefed up already Dave, with wire and solder, just as you say.

Already have an account? Dave, thanks for all the effort you’ve put into checking your own controllers.

Endless Sphere – Development version

I’ve got it back together now and just tried it. The ku663 between where the orange and white wires are soldered is also an input to the CPU. About Us Contact Hackaday. So I would guess that last multiway had all the negatives in one black wire soldered to the board and all the 5v feeds in one red wire. You should Sign Up.

The throttle can’t be in the three speed connector because there is no voltage to be found anywhere on the connector. Sadly, I have no pictures of this piece cotroller the build – it was done fairly hastily. Is the one next to the common grounds on a joined pad or on one marked SD.

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. I figured if the others didn’t arrive in time, maybe I could find a match for this guy later.

Building an electric scooter with some real power. There are other places where they’ve clearly optimized for cost reducing part count, particularly around the throttle. If we can’t figure it out between us, I’ll open it. I snipped off the connector and wired in the brake line, nothing to it.

And does it work backwards?

I’ll work carefully through your comments with a magnifying glass and meter on my controller board, then report back on here with whether I’ve got it going or not. Its partner will be a black ground The red wire near where the battery comes in will be the 36v to the panel.

So, FOC already has a pretty good estimation of the angle at any given moment not only to maintain at 90, but to change that when doing Field-Weakening If you do not have those two vectors, you are basically in speed control. You must log in or register to confroller here.
