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.

20 inch hub motor conversion kit for electric bike

Q: I have looked at your leaf motor and want to buy one bike kit includes hub motor wheel, BLDC motor controller and twist grip throttle. I am looking at a 20 inch wheel with 1000 Watt hub motor, but I think that one may not be enough to handle the load. I am looking to build a three wheeled vehicle and look at the possibility that I may need to power 2 or all 3 of the BLDC hub motor wheels to achieve my goals. I am thinking of building two or three of these three wheeled vehicles. What can you do to help? A: Thanks for you are interested in electric bike conversion kit . For my personal idea, use a 20" 1000w brushless hub motor to convert a front wheel, front drive is much better. If possible, order two sets of 20" 1000w BLDC hub motors with one high power brushless motor controller to convert two rear wheels - rear drive. It’s no problem with forward and reverse. But when you turn left or turn right, you will get a little trouble. Only under much lower speed can turn left or right. Convert two wheels that is enough. If you always ride on flat road, only convert one front wheel. Q: I was thinking the 20 inch 1000 Watt bike conversion kit as exampled. What I had vision was to use 3 BLDC motor controllers, but using one on front and one larger for the 2 rear hub motor wheels may make things easier. For turning it is easy to not worry about differential control on the rear wheels, such as turn radius larger than 5 M differential on the rear wheels is not consequential as centerline width is app 720 mm. It would be very easy to turn the inside wheel off by disconnect, or turn the rear drive off all together and let the front wheel do the deep turning. So what I need is real pricing for three sets of bike conversion kits includes three BLDC hub motors, two BLDC motor controllers. One 1000 W for front, and the other 2000 W for the two rear hub motor, or what is possible to have one 3000 watt drive to run three brushless hub motors? Please note that the vehicle will need a lot of power to traverse some of the steep ramps and terrain. It seems that the 1000 W hub motor seems to have app 17 Nm torque and that would mean that three would have just enough torque to carry the load. A: We suggest you order below bike conversion kits : 1.3 sets of 20" 48V 1000W hub motors (one for front, the other two for rear hub motor) 2.1 set of 48V 1000W LCD BLDC motor controller to drive front wheel, LCD display speed, battery gauge. 3.1 set of 48V 2000W brushless motor controller to drive two rear wheel 4.2 set of thumb throttle, one of left side to control front wheel, the other on right side to control right wheel(when turning, loose right side throttle, just twist left side thumb throttle) 5.1 set of brake lever to control three controller, when press lever, all of three controller will cut off power 6.1 set of three button switch used to control reverse, horn, lights Hub motor, BLDC motor, bike kit, bike conversion kit supplier: Leaf Motor Technology Co., Ltd Website:https://www.leafmotor.com

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.
