Need help choosing controller for older hub motor


10 µW
Feb 23, 2018

I recently bought a chinese electric scooter, named as Keeway Leone Ecopower. Manufacturing year is 2011.
I am unable to find any meaningful data on this thing, other than some general photos and specs about charger.
Motor has text on it saying Evader EV1000 but searching by it gives nothing. Cannot even tell if it brushless or not :)
All I know, is that it is supposed to be a 48V 1000W scooter. It was running four small 12V agm or similar batteries which are gone and also motor controller is gone.
Motor has three rather thick phase wires and also sensor wires.
When I connected a 48V adapter to battery wires, it came alive in general - lights and everything working.

Now I am thinking about changing it to 18650 Li-ion battery which I have a lot at hand and maybe a bit stronger motor controller. Something like 1500-2000W and maybe even a bit higher voltage - 60 or so.
Can maybe anyone identify the motor and help with selecting correct controller?
So far I have found these:

As I have seen few older 12" hub motors out of which some ran with KT controllers and not Focan ones and then others that ran only with Focan and not KT controllers without making any sense to me as of why so, I'd like to plan and buy the correct one right away and not start blindly testing different ones.
So any help would be greatly appreciated...

That's a brushless motor. The big Y/G/B wires are phase power, small Y/G/B wires are Hall sensor outputs for their respective phases, red and black wires are +5V and GND.

You can use practically any brushless controller, but you'll have to reconcile the plugs one way or the other. If you want to run it at a nominal 2000W, you'll need 50-60 amps at 48V or proportionally less current at higher voltage. A controller that has a self learning mode makes it easy to set up, but it's a convenience rather than a necessity.

Whichever brushless controller you have in the right power range will work, but you have to get the wire assignments correct because there aren't industry standards for it. I would choose a controller based on what display I wanted to use (or whether I wanted a display at all).
