AliExpress accidentally sent me a Sinewave Controller, can't return it so I need help figuring out pairing 2 motor...

[Klauts]

Hey everyone, I was accidentally sent think KT 25A Sinewave controller instead of a squarewave https://a.aliexpress.com/_mK0haAA

I have a Greenpedel G500S 750W motor... https://www.greenpedel.com/g500s-350w-500w-750w-high-torque-fat-tire-gear-hub-motor.html

I'm having a hard time finding any guidance at all on the topic... It uses waterproof connectors with a 9Pin motor wire just like my old KT squarewave but my understanding is that I'm going to need to switch the ordering of the phase wires?? Seems difficult considering it uses a 9 pin... Not very swappable.

Any help would be greatly appreciated

Sounds like their mistake was in your favor

Whether the controller is square or sine wave has no bearing on whether or not you'll need to swap phase or hall wires around. Did you try connecting it already without success?

They sell an extender cable for that plug type, you can cut it in the middle and splice it in the new order to make your own adaptor.

You can use it to test the run order first by just doing temporary twist connections, then real ones with heat shrink after it runs.

The sale page doesn't say, but does yours have a self learn function (usually a pair of wires that plug into each other)? I could not quickly find any pages that say if KT controllers do or do not have this function, but it is a common one these days, to automatically set the timing for phases/halls so you don't have to swap wires around.

If you have a KT LCD for it, you might see if you have the C2 setting listed. Some of the manuals I see online say this controls the "motor phase mode", but none are clear on exactly what the different levels in the C2 setting do, just that it starts out in (for example) a "Quantum Phase Mode" (other manuals or LCDs may have different terms).


FWIW, it shouldn't make any difference as far as hall/phase order between sine and square (trap) controllers. But any controller could easily be wired differently than another of even the very same model and brand, but different batch, for instance. (same for motors). This shouldn't happen, but it isn't uncommon...and with different brands or models of controller (or motor), it's probably 50/50 (or less) that the wiring order would be the same.

Many of the KT square wave controllers are sensorless. If he has a sensorless motor, that's a problem.

Looks like it has halls and maybe speed, at least the connector does.

My guess is, since his old controller was a KT with the same 9 pin connector, and they sell both the square and sine wave versions on the same ad/link, they likely use the same pins for their connectors, regardless of square or sine wave. Absent screw ups during manufacturing of course.
