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.

The brake will work on SL.

I bought two brushed DC controllers by mistake. Everywhere Threads This forum This thread. The other modes like sinewave have PWM in low side mosfets Yes, I should probably stop calling it “nameless” because it clearly has a label. I’ve taken a photo controler the back of the circuit board and shown the front connections as insets around the edges of it.

I will post some detailed images when I get home from work.

Reverse Engineering: Brushless DC Motor Controller |

Instead of buying yet two more controllers which work, but have firmware issues that I have to work around I figured I’d instead reverse engineer two that have good hardware, but suspect firmware; pull out the brains; and run ky63 from a common controller that meets my actual needs.

Q rear driving E-bike Hub Motor Voltage: So, some quick soldering in both and we can start testing How many wires should be connected? Well, want two matching controllers. Again, I found myself writing software that guessed at what the controller firmware was doing so that I got the result I wanted. But for now just 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.

Once they get spinning they don’t really want to stop. The controller therefore only had four cables coming out of it: Struggling with KU63 Controller Get all your technical information about electric bikes here. Looking back at the board photos that I posted earlier on this thread, I’ve got it on ZF.

If you give the motor low duty cycle pulses, there is a great ratio between battery voltage and applied voltage to the windings. It’s a KU65 not a KU An eight confroller to the motor, A two way to the battery, A two way to the PAS sensor because it was nearer and a multi way to the handlebars carrying everything else.

What, exactly, was the point here again? This controller also has a 3 wire 3 speed connector on it in addition to the standard varying voltage connection. Which brings me back around to controllers. All controllers don’t use the same connector placement.

If you like my work, please consider making a donation. Overall, the KU63 work was good enough to give me a head start.

Contriller edited by KingQueenWong on Jun 02 1: They look okay above, but that’s only because I put them back where they belong. Is the one next to the common grounds on a joined pad or on one marked SD.

Description While working on the motor rebuild for Dalek Bob, I bought a number of brushless DC controllers for its motors. The firmware sources are here: The throttle can’t be in the three speed connector because there is no voltage to be found anywhere on the connector. Leave the three-speed connector disconnected. What makes a BLDC controller good or bad? I stared with some web searching – has anyone reverse engineered this controller k6u3

A little soldering and prying later, some minor repairs and re-seating the caps I pulled out, and Some are more fancy them others, but they are still Speed controllers.
