Hello, I got this ebike fatscooter controller super cheap but without any wiring instructions. Here is the pcb pictures, please help. Main leads to motor and battery are the copper tubes towards the top. This controller is not available on the Internet, it is not soco, not vector, not kelly... Preposebly on a electric fatscooter earlier.

What, completely and exactly, does the labelling and all markings say on the controller, everywhere on it that there is a marking, including those molded into the plastic and/or etched into the metal?

That information will probably help us help you find the manufacturer and thus probably how to set it up. Good clear pictures of the labels and markings will help, especially for anything that is not in English, as google translate may be useful in figuring out what they say.

The one picture that shows the controller indicates it's similar to a number of newer types of controllers (such as the Fardriver), but there's not enough detail to tell us which one it is.

Here is the pcb pictures, please help.
Unless it is in the link that doesnt' work, there are no pictures of any PCBs (printed circuit boards), only one of the outside "top" of the controller, with some wires attached, and one of a drawing of some connections and labels.

Note that it is not typically necessary to disassemble a controller to get pictures of it's PCB(s) in order to figure out the wiring (but sometimes it is, as a last resort when no other info is available).

Main leads to motor and battery are the copper tubes towards the top. This controller is not available on the Internet, it is not soco, not vector, not kelly...
If you know it is not vector or kelly, why does your thread title say it is a new type of vector kelly ebike controller? This is very confusing.

I don't know what you mean by this. Please clarify so we can help with it.

This link doesn't work.

To help us help you better, please link where you found the information that you have marked there; we may be able to figure out more from any other information they provide. If you determined this information on your own, it would help if you explained your testing method used to figure these specific things out, so we can help you determine other testing you can do to figure out the rest.

Here is picture of my setup testing:

What exactly is setup there? (for instance, what is wired up, and what are the wires connected to at each end? What works, and what doesn't (if anything)?) Just a picture with no explanations doesn't help us help you very well. :(


BTW, if you are testing the motor loose on the table(?) like that, it's very likely to suddenly twist and damage the wiring, or even drag your whole setup right off the table and physically damage things (possibly even shorting stuff together while yanking wires).

I highly recommend mounting the motor in the scooter(?) it is for, with the scooter(?) upside down to keep the wheel offground during testing, but securely mounted at the axle so it can't spinout and damage or destroy the wiring/etc.
 
I fixed the first link in my first post, there is when i disassembled. I looked up the meaning of the markings on the pcb. Also I have searched at all the markings otherwise and can't find manufacturing, the label reads: sjanehui vector sine wave controller

I have no clue what controller it is, batch number starts with 2020 so maybe 2 years old controller. It is new in the way that I dont now what it is, it is similar to kelly, fardrover, soco controller and some other brands like golden motors.

There is also a chance it needs to be set up to a display to work, I think connecting vcc to p+ turns the controller on (or im just shorting the 5v output or something)
But connecting the brake and setting regen on doesn't effect the motor when i try to spin it, also I can't get the throttle to make anything happen. Throttle is connected to red 4.3v, black gbd, green to SD.

All I want is for it to turn on and work, if you have any ideas. I have tried for hours to find the controller in China searching and everything I could. Thanks for any help.

This is the markings:
Sjabehui vector sine wave controller
60v
35a
(misspelled "brave level, High Level"
"voltage of handle 1. 1 4.2v
Batch no. 20200515

On the pcb:
DZ-VB2.4
PL28

S0. 30 (30 amp version I think)
685326

(random stickers on pcb: microprocessor I think 8B1055F1 (didn't find on Google)

I can't disassemble again because my connectors are soldered.
 
Update: It turns on and there is another throttle signal cable that worked. Only problem is the the motor locks itself with power when I try to use the throttle.
So if someone can help me figure out how to disable this lock thanks.

So it didn't come with the wiring harness that plugs into that big connector?

No... There might be some self study thing that I have to connect or maybe hall needs to be connected or something. Presumably it was made for fatscooter motor so maybe it is programmed for that...
I found similar controllers on alibaba but no wiring information. Search vector controller 60v... Huang is the company I think.

I am thinking there is come connector that unplugged triggers locking the motor. Or that you need to use a display and turn it on. There is a rxd and txd cable for display I think. You can see on the link...
 
Kind of looks like this controller manufacturer from an overall design philosophy perspective. And has the same 3x10 header.

There are wiring manuals on their site.

Sadly it's not the same.

Search this:
"Tk Motion controller dc motor controller for motor cycle" add 60v if it isn't found on alibaba. This controller is almost identical to mine, but no wiring information... I will try contacting seller.

Hi.
I see it's been a while but do you have any news about the controller? I have the same type only diff. model EM25-45. Trying to find as much info as I can about it but no luck so far.
Thanks.
