Connecting Ebike NEW front e-wheel with controller. HELP PLEASE!!

I urgently need you help with wiring diagram of 8Fun Bafang BFSWX02 20-1503196620-6; 48V 500W front wheel motor (XY48V500W12020104 producer brand name doesn`t writed) and Yuan Lang Intelligent Motor Controller
Model: YP-12-133 1:1. Will not bad if you sent to me all technical documents (and not only) what you have, thats will help me and my electrician partner a lot.

I need to connect a new 48V 500W front wheel motor (XY48V500W12020104 producer brand name doesn`t writed) with
Yuan Lang Intelligent Motor Controller
Model: YP-12-133 1:1
Voltage: 48V
Embede Voltage: 42V
Angel: 120
Brake Level: High
Production Date : 2014-12
Code: 1412A125529
whitch was connected early with 8Fun Bafang BFSWX02 20-1503196620-6 front wheel motor.
The problem is that my burned out 8Fun Bafang BFSWX02 20-1503196620-6 front wheel motor got 9 wires instead of a new 48V 500W front wheel motor (XY48V500W12020104 producer brand name doesn`t writed) which have 8wires (doesn`t have WHITE wire).
Please write to me if connecting is not possible or even if could appear any other reason.
All this stuff is used on Pedicab/Rickshaw/Bike taxi.

I do not have or know where to find any wiring diagrams for that motor or controller, however I do know some information which will help.


The white wire on your old 8Fun Bafang motor goes to a temperature sensor inside of the motor. Since your new controller has 8 motor wires instead of 9 it does not have an input wire for a temperature sensor. You can simply leave the controller's white temperature sensor wire disconnected and it will still power the new motor with 8 wires.


Motor temperature sensors are optional inputs on most controllers so the controller should operate the motor normally without a white wire connected to it.


Please let us know how it goes.

If someone got, knows how or where to get- Yuan Lang Intelligent Motor Controller Model: YP-12-133 1:1 connecting diagram- then please send it to me (I have send twice email to manufacture). Even connected ebike motor wheel with Controller does`nt work (we tried defferent wire connections with 8 wires). My electrician work with a Controller (he need to check that everything is right with controller itself) and he said that without Controller connecting diagram will take a lot of time and money to check where is trouble is!((
