I have no idea :D
At some point half a year ago I picked up the motor, for future uses.
Now I have it working but I still do not know what to do with it.
I even have about 2k pcs of 18650 battery cells.
In theory a car-like-thing. Smart ForTwo is always an option but a bit boring. Or maybe a...
It supposedly allows 4 different throttle versions. 0-5kOhm, 5kOhm-0, 0-5V and a 3-wire potentiometer 1-10kOhm.
The 0-5kOhm potentiometer is the simplest.
Bought one today and I am happy to say, that with this one I got it working.
It mostly came down to that one broken mosfet, after that it...
Made some progress with controller.
Cracked it open, looked up the contactor mosfet and found it to be dead. IRF3710 - rather big thing - 200W and 100V, max drain 57A -- but still dead.
Replaced it, reassembled the thing and what do you know - now I get healthy single LED blink out of it and...
BP to B+ and BM to B- are there, I just do not keep it connected overnight.
When testing I connected the precharge between BP and B+, held until voltage is reached and then connected the BP-B+ directly.
For me this is first time to meddle with this type of controller and I cannot find much in...
Funny thing is, that in manual it does mention precharging but on schematics there is no resistor anywhere.
Manual is here: 1253 manual
The schematics in previous post is not from that manual. It is from some other Curtis DC controller, it just made more sense, so I used that.
I have not...
I recently got my hands on a forklift DC motor, papers that came with it say that it is capable of 10kW @ 75V and 165A at 2800rpm.
Weight is 44.7kg.
Tested it a bit with car battery, seems to work alright.
As it is oil pump motor, it only has 2 terminals and always rotates same way.
Now, to get...
This is very likely, yes.
I did not really have my hopes up anyway when replacing a controller on old-tech 2011 machine, made to run with four acid-batteries.
It has already gone quite well since the thing is driving fine.
And I think the phase wire coloring matches correctly this time, though...
Hi Chalo,
thanks for pointing me to right direction.
By today I have ordered a rather random 2kW 48V controller from eBay and got it all working fine just yesteday.

Only thing I do not yet have is the ammeter...
Hi
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...
As said, I don't have it connected to scooter at moment, so cannot check.
I did read a lot and went through all I could but I seem to have thrown away all the notes I had also.
Seller recommendation was this and I know I did test that among others.
P1: 88 (100 for 500W-engine)
P2: 1
P3: 1
P4: 1...
When I had KT controller connected, then the C5 setting (max current value (A)) to 03 - "Max current value /2" and C12 (minimum voltage (V)) to 0 - "Default value -2V" did have small effect.
But what most baffles me is exactly the same thing - works with 500W Focan and not working with 350W KT...
Hi
Thanks for all answers and helping hands.
Question mainly is trying to figure out the logic and reason behind this. I can run it with this big Focan controller alright but I cannot understand why others does not work. Also as Focan has no display or buttons, switching on/off both motor and...
Hi
I'm having issues with new kit. Have tried all I can think of and no idea what to do next.
Motor akm-13.0 250W and 36V in an 16" wheel.
Controller KT36ZWSRMT-XW01DL 350W 36V with LCD4
Battery is also almost new 36V 10s5p with about 12Ah. Actually have tried with 3 different batteries too...
