How to connect wires with leaf 1000W hub motor electric bike conversion kit

I have wired up some items to my bike, but I am unsure how to wire certain things up. Please view the pictures to see what I mean: Attachment called - Controller Wires - Which color to which color of the hub motor do I connect to ? There are three thick wires on the BLDC Motor Controller that look like connectors to they connect to the motor. Unfortunately, I do not know what color to map them to. I did connect blue to blue and green to green, but the wheel responded briefly, then the LCD screen shut off.. I would have to switch the power off and on again for it to come back. I have not gone any further as it gave me the impression I could do some damage if I continued. Attachment called - Bike Motor - Which colors connect to the colored wires of the brushless hub motor Controller This is the connectors on the hub I need you to identify for the Controller, which wire connects to what? Connecting the green to green, black to black, there is another yellowish/greenish wire on the motor that has no equivalent colored wire on the controller. The controller has a black think wire - does this yellow/green wire connect to the black? Attachment called - Light Switch & wire I do not know what this is and what it is used for - I presume a light to work from the battery. Where do I wire this to? Does it connect to the BLDC motor controller? if so, where. I found your video's quite difficult to follow as it is difficult to work out what is connected to what and how and I do not see anyone triggering anything to start the electric bike motor wheel when it starts working. Would you be able to send me some diagrams or written instructions on setting this up from scratch? See attachment ‘BLDC Motor Controller Wires’: The green and blue wires are present on your diagram, but the thick black one isn’t – where is it supposed to go? The other attachment ‘Motor Wires’: There is a Dark green wire, Dark Blue wire and a Yellowish Wire (I say yellowish as it seems to have a hint of green in it – in other words it is not too clear).. The green and blue I can match to the green and blue on the brushless hub motor controller, but what about the Yellow/green wire? I have attached these wires in various combinations, with the power coming on and empowering everything other than the wheel. The electric bike motor wheel will ‘shudder’ when I slightly twist the throttle but the whole thing will shutdown and I will have to turn off and on again to get it back. I did this a few times with the same result. I rearranged the wires again, with all items turning on, but the bike motor wheel did not respond. I eventually realised the controller wire heating up and turned everything off. I have left it for a while, but when I tried it again the power did not come on any device.

12 inch BLDC hub motor for electric bike ?

I'm in need of a simple installation electric bike motor for a special application. The subject BLDC motor look that will perfect fit our needs. I am ready to order the first to complete the prototype, but will appreciate your advice if will work properly under the following conditions: 1. Max torque 15 Kg-m 2. Speed 0 to 10 Km/ h 3. Distance between charge batteries 5 Km Important is smooth start motion (no shaking) I understand the HBL-12" 24V 250W hub motor is good for the working conditions On your internet site for this size electric bike motor there is technical performance for the 36 V model only. I need only 5 Km range between battery charges.But very important is the star movement from stop (0 Km/h) very smooth, slowly start to move otherwise possible damage of the airplane nose wheel if start move quickly and shaking. Then the question, will 36 V brushless hub motor be better than 24 V ?Since 36 V have smaller currents I have the feeling will perhaps be better starting to move more smooth and slowly... Will be great the customized low speed. But please note that this special application, not yet a commercial product, then in the last phase of development. Will you customize low speed electric bike motor at the present stage of just one unit ? Looking all your products, the choice was your Model:HBL-12" 24V 250W hub motor because so simply installation. But also, although is not our preferred solution because much more complicated installation, could be your Stepper DLDC motor, which in this case the speed can be defined by the ratio of the gears, and the diameter of the wheel (which in our case is important to be small since the device shall be below the airplane... Max 12 inches but smaller is better...) Maybe the Stepper DLDC motor have the advantage of very smooth start motion ? It is our concern to have a very slow and smooth start motion... Actually from your specifications you give for the max torque of 16000 (the point we are most interested) 243 rpm at 18 Amps, which is for a 12 inch wheel about 14 Km/h, then is very near our 10 Km/h. We believe, if we do not read wrong your performance data for the 36 V HBL 12 inch electric bike motor as it is specified is OK... Please correct me if wrong. The fact that the motor will be capable of much high speed we believe should be not a trouble, we can easily put a limitation of the speed. Still extremely important is the smooth and slow increase speed from 0 Km/h (stop) with no shacking,but we understand this is related to the BLDC motor controller, which we will test but feel should be not a problem. We need as precise as possible to control smoothly the speed from stop 0Km/h to max 10 to 15 Km/h... with slow increasing speed and keep low speed 2 to 5 Km/h .Then NOT AT ALL "on" and "off" ! Another important issue is the torque. We need minimum 15 Kg-m torque, better if 20 Kg-m... ( 147 to 196 Newton meter)- Here is a big doubt with the numbers on your performance data since indicated mN.m 16000.0 ? if lower figures could be difficult start motion when in surfaces as grass. Then I need to order not only the hub motor but also the relevant BLDC motor controller and electric bike battery. When you say 36 Volts make no difference but preferred in Europe. I choice 36 Volts... as you say... but if 24 Volts is better, off course we change to 24 Volts... we need the better solution. Normally the device speed shall be about 5 to 8 Km/h... for safety reasons... and torque between 147 to 196 Newton meter at 0 Km/h to start motion.

How to build spokes on hub motor for electric bike ?

DIY electric bike conversion kit and convert your bike is funny. Sometimes we prefer to purchase spoke hub motor , bike rim and spokes. And build spokes on electric bike motor by ourselves.
If we want to convert 26inch front wheel, we should purchase 1 set of front spokes hub motor, 26inch rim and 36pcs of spokes. We can purchase them from leaf bike motor shop online.
Received goods and check them:
1. How many spokes you received. Generally we need 36 pcs spokes to built on hub motor and 12 gauge spokes for electric bike. 13, 14 gauge spokes are too thin, just for common bike.
2. There are 36 eyelet on bike rim and hub motor.
3. Check nipple and the dia. of eyelet on rim, make sure the nipple can put into eyelet.
Calculate the length of spoke :
If you use 205 leaf front hub motor, the eyelet to eyelet of rim is 511mm that is 26inch rim, spokes should be 155mm length.
You need below tools to install spokes on hub motor.
1.iron shelf
2.slotted screwdriver
3.nipple wrench
4.magnet
5.rubber hammer
6.tape measure
7.calipers
Done check, everything is okay. But we found the dia. of nipple is 4.5mm and the rim is also 4.5mm. These eyelets are too small. See pictures.
Get an electric drill and 4.8mm aiguille. Drill 36 pcs of eyelets on bike rim first. Adjust the iron shelf so that the dia. is 100mm. Because standard front fork is 100mm. Then put the rim inside the iron shelf, hold on the hub motor. Make the first spoke wear into hub from left side, the next from right side. One by one from left side to right side. Done install all 36 pcs of spokes, please check them whether correct. See pictures.
If no problem, we should hold spokes on rim by nipples First hold one spoke on left side, then cross to fix another spoke on left side. Next step, cross two spokes on rights side and fix them. Left side, right side, a group of four spokes. See pictures.
Fix all spokes, we should use wrench to tight spokes a little, please don’t be too tight. Use hand to turn wheel, make sure there is no noise from friction of rim and nipple. Use rubber hammer to knock rim when the wheel is running so that the rim will be not jumping up and down. Still to tight spokes a little. See pictures.
Turn wheel, you will find the rim from left side to right side. In order to make the wheel running in the middle. We use calipers to measure and get the data. Then use a magnet to hold a pin. See pictures. If rim to the left, we tight right side spokes or loose left side spokes. See pictures.
It takes about 1 hour to build an wheel.

How-to-build-a-hub-electric-bike-motor

These days hub electric bike motor wheels are used for e-bikes widely. Nearly all of hub bike motor are brushless gearless. Because of low noise, high efficiency, long life are popular with riders.
Order 1 set 12" 14" 16" 18" 20" 24" 26" 700c 28" inch hub motor kit, convert your common bike to e-bike is so easy. Directly front or rear drive your bike.
The important part is an engine -hub motor. How to build this electric bike motor?

Step 1: winding
Calculate motor power, speed RPM and confirm what type of copper wire would you use. Next is fix a rotor on the steel shelf, wind copper wires by handwork or machine. It takes about 1 hour to done it by handwork. And should use rubberized fabric to wrap your fingers. Nipping copper wires will break your fingers.
Step 2:soak paint
After winding should soak paint in order to be insulated. Use brush to put the insulated paint on the winding and make sure be soaked everywhere. It takes about 24 hours.
Step 3:press axis into rotor
Put axis into rotor winding and use a key to fix axis. Use A-B glue to paste three hall sensors on hub motor rotor, put 9-pin (three pin/each hall) into PCB and use insulated wire to fix it. Put 8-pin cable inside the axis and heavy yellow, blue, green wires to connect the three copper wires(Phase A,B,C) separately. Thin red, black wires are be weld to PCB + and - .
Step 4:paste magnet
Paste magnet inside hub, one N pole, next S pole ..one by one. More magnet, higher torque, more power. The height of our magnet is 30mm,6mm higher than other hub motor. In market,24mm high magnet only build max 500w electric bike motor. So our bike motor works at 36V can reach 750w.
Put the rotor winding inside the magnet hub, be careful hand. It has powerful magnetism.
Step 6:install two covers
Before installing both covers, we should press bearing into cover. Use hexagon wrench to tight screw nuts. When you hear "poop" from electric bike motor. That means install correctly. Done it.
Power on battery and use bldc motor controller to drive this hub motor. If no any strange noise. It's okay.
