Color code (wire designation) of rear hub 1000w (Luna) motor

[orcasmarx@yahoo.com]

I am pretty new to the vast expanse of e bikes. I have a cheap 300w 24v Chinese Ebike assembled by a US company. When it developed problems I called them up and they sent me the wire designations (color code) of the wires coming from the motor and a short description on what I would get for example if a hall sensor was blown or the controller was bad. Fast forward (8 mo) to today where I purchased a 1000w kit from Luna). Their kits do not have PAS so I bought a 9 fet Infineon controller from em3ev (great people by the way). I call Luna and ask what color of wire goes where and they don't know. I was totally taken aback and basically told them the fact that they didn't know was unbelievable to me and a few other choice words, no name calling or anything like that. Just that I was having trouble wrapping my head around the fact that they didn't know the wire designation of their own product. Well to make this rambling short one of their tech's thought I was way out of line.

So I now ask the community. I know the motor wiring code is kinda universal but does anyone know what color wire goes to each of the phase, hall and other signal wires? Or at least point me in a direction. I have read the posts on endless sphere and they talk about how to test them out to find the right one but I am hoping that someone out there has wired a hub motor (especially Luna) to an Infineon controller. I am building everything (lacing my own wheels, building my own battery etc. Any help would be greatly appreciated. Sincerely, "OVER MY HEAD"

Just double-checking, is it this one?:

If yes, there are three fatter phase wires, and 5 small hall sensor wires. Two of the small hall wires are the red/black positive and negative (ground). Three of the small hall wires are for the 5V signal...yellow, green, and blue. You only need to swap-around those three to find the right combination.

You won't "hurt" the motor by switching the three fatter motor phase wires around for testing, but there is only one combination that works "best", meaning the lowest "no load" current draw, while spinning in the correct direction. I seem to remember there are only four possible combinations.

If you pull the motor side-plate off, you can see which color of hall signal wire is in the center hall-sensor, and that would eliminate one color-code identification. Then you'd only need to switch the front and rear hall wire to find forward or reverse.

Its been so long since I mixed-and-matched a controller to a motor, I probably said part of this wrong.

Even if you get a wiring diagram, it probably won't help. All the common hubmotors are three phase, but which phase is which? One supplier might call them A, B, and C, but...is he going clockwise or counter-clockwise? The three phases are identical, so which one do you start on? I'd like it if the top four north american hub suppliers agreed on a standard, and China would make the wire colors anything you want. But...they are competitors, so...they don't want you to use one of their products with a product from the other guy. They all stubbornly refuse to use the same connectors and wire color-code. In fact mixing and matching components from two different suppliers will likely void the warranty.

Batteries are a piece of cake. Two fat wires, red and black. If somebody sells a battery with two black wires, easy to see which is the positive with a cheap multi-meter. Since you ordered the Luna kit, maybe use the Luna controller until you get the wiring sorted out so you can go to the higher amps on the 9-FET then?

Here is the master thread from Fechter for determining the wiring on a mystery motor.
