The second picture shows three phase wires. Do you mean strange because two are orange and one black -- no correlation to the green, blue, yellow of the controller? There is no standard for wire color anyway, but the strange orange and black use may be relevant to the next point...
For the 7-wire cable, the motor is offered with 3x Halls and NTC temp sensor, which require +5VDC and a shared ground, so that's normally 6 pins. Maybe they're running the Halls and NTC on separate grounds? That would give 7 wires.
However, the cable is shielded when it certainly doesn't need to be -- in fact, there's nothing to connect the shield to. So maybe they just used whatever extra cable they had laying around, like the orange and black phase wires, and it just happened to have 7 wires?

Thanks a lot for your helpful reply atkforever,atkforever said:Kelly has auto-identification it means if you tick the option in the config program then when you will power again the controller it will find the right hall combination and save it (and I suggest you do that, even on a motor with obvious phase colors + hall colors the motor wasnt running well untill I did that auto-identification thing).
To find the right +5v and gnd you Can apply a voltage bellow 20v (5v ideally) on the supposed positive wire, same for gnd, and mesure the voltage between one Hall wire and gnd. If when you turn the motor by hand you get something around 5v, then you've found the right + and gnd. This hall testing procedure might help you :

If the motor is running separate grounds, they're going to be, well, intentionally separate -- they won't have continuity.atkforever said:So as said above there might be 2 ground wires so I'd check continuity between every wires. If you find 2 wires that have continuity, they might be GND, but this could also be 2 +5v wires...

Looks like you can trace the wires through the PCB to the Hall sensors.Sparfuchs said:I found a picture of the sensor board the motor uses. Maybe it helps to solve my problem ?hall.JPG
Split to bridged in the PCB back to split? Seems unlikely, but I guess anything is possible.. But that would mean testing continuity isn't much help.atkforever said:That's not 100% predictable, GND could have been splitted because it needs to be on two plugs.
