E-bike Not work – electric controller issue or hub motor?

Riding an electric bike is a funny thing.Sometimes,while riding happily,it stop working and can’t re-start.
If you think your lithium battery is new,can’t cause this issue.Now you should check controller or bike motor,how to check?

If you have volt meter,you could measure as below? So that you can make sure the problem comes from controller or motor
If you can get the same data as below 1, that means controller’s everything is good
If you can’t get the same data as below 2,some hall senor has problem.

1. Connect all wires,power on.Just disconnect that white big plug with five wires( yellow,blue,green,red,black)
Then measure controller’s hall sensor:
* The voltage of red and black is about 5.0V
* The voltage of yellow and black is about 5.0V
* The voltage of blue and black is about 5.0V
* The voltage of green and black is about 5.0V

—————————————————————————–
2 Connect all wires,power on.Also,connect that white big plug with five wires( yellow,blue,green,red,black)
Then measure motor’s hall sensor:
* The voltage of red and black is about 4.5V
* The voltage of yellow and black is about 4.5V or 0V (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)
* The voltage of blue and black is about 4.5V or 0v (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)
* The voltage of green and black is about 0V or 4.5V (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)

electric bike conversion kit has a very big advantage

1886, when the world’s first gasoline car invented a four-wheel, its 18 kilometers per hour to run, but also when the carriage speed, many people laughed at the “monster”, but some far-sighted people such as Karl Ritter • Buddha Li Qi • Mercedes-Benz, Ford, etc., but insight into their vision for development and actively involved in this industry, which achieved a lot of great car company. 100 years have passed, and now, another change will occur in the car – electric bike conversion kit has been coming to us, such as the face of such changes, semiconductor suppliers, how to choose?

“Infineon to enter the field of bike conversion kit has a very big advantage, electric bike conversion kit with a major difference between traditional car is built on top of a set of high-pressure system, and we have been in the field of high power devices occupy a leading position.” Recently, a press conference at Infineon, Infineon’s Automotive Electronics Division electrically driven, product line director Mark Munzer stressed, “In addition, we are the world’s largest supplier of automotive semiconductors, so that we can just combine the two expertise up and applied to the electric bike conversion kit, we can provide the best to the bike conversion kit solution. “He seems to corroborate discussion, we note that in the 25th Electric Vehicle Conference, only a Infineon exhibitors and other semiconductor suppliers leading supplier of automotive electronics were not participating.

Similar to long term loans online approval, unsecured loans consist of multiple lines of credit that have no use of proceeds requirements. Whether you need to pay for working capital, construction or pay a franchise fee, unsecured loans can help.

Now, with rising gasoline prices and gasoline vehicles environmental pollution, electric bicycle conversion kitinstead of increasing demands for high gasoline vehicles in China, and some even shouted “Stop petrol cars by 2015,” and other slogans, however, countries The Government has increased the electric car does on the support, China, for example, June 2, 2010, Chinese Ministry of Finance, Ministry of Science, Industry and Information Technology, Ministry of National Development and Reform Commission has finally issued a joint “regarding the development of the private purchase subsidies for new energy vehicles pilot notification “(hereinafter referred to as” Notice “) to determine in Shanghai, Changchun, Shenzhen, Hangzhou, Hefei and other five cities to start private purchase of new vehicles to subsidize pilot energy, electric vehicles the maximum subsidy per 60,000 Yuan, plug-in hybrid maximum subsidy per 50,000 yuan. In addition, the Chinese government and other public transport electric bus has also given large subsidies, these policies will undoubtedly greatly boosted the confidence of the global market for electric vehicles, because China has become the world’s largest car consumer, the consumer behavior on the global automotive market impact is very large.

History of torque bldc motor controller

History of torque bldc motor controller
The late 1850s, the initial low-speed torque bldc motor controller is a pump stator and rotor components evolved, this component consists of a ring gear and one with matching gear or rotor component. The fixed ring gear and the shell can be connected together, the oil from the port into a center to promote the revolution around the rotor. This slow rotation of the rotor drive shaft through the splined output as cycloid bldc motor . This after the advent of the first cycloid motor, after decades of evolution, another conception of the motor began to form. This motor is installed in a built-in ring roller. With roller motor provides high starting and running torque, roller reduces friction, thereby improving efficiency, even at very low speed output axis can produce a stable output. By changing the input and output flows in the direction of the motor to quickly change, and such values ​​in both directions of torque. The series of motors have a variety of displacement were selected to meet a variety of speed and torque requirements.

My 26 inch rear electric hub motor kit works

Q: Received my 26 inch rear electric bike kit. Finally managed to get it all working. The LCD display does not go over 20 mph ? Can you think why?

A: Do you make you hub motor “reverse”?

* If you make the three button switch to be “R”, bike motor will be reverse, the speed is slow. Make to “L”, bike motor will be forward.

Q:I have disconnected the three button switch and now seems to be working. The display when the ebike is in use does not go above 20 mph. does the display after you have set the mph/kmh mean ? It says p1, p2,p3,p4 and p5. What are the correct settings for these ?

A:Your electric bike kit can reach 40 mph without load, we test it. Even if you ride, still can reach about 35mph.
Please set the wheel size to be “26” It’s wheel size.
* Power on, turn on LCD, then press “up” and “down” button for 2 second together.
1. Then max speed will flashing. Make it to be max 72kmh.
2. Then “kmh or mph” will flashing. Press “up” or “down” to shift from “kmh” to “mph”. Then press “ON /in the middle of button” to done setting.
3. Then “wheel size,8,10,12,14,16,18,22,24,26,700 or 28” will flashing. Press “up” or “down” to shift. Make it to be “26” Then press “ON /in the middle of button” to done setting.

* After setting these 1,2,3.Then press “UP” and “Down” switches. Then start to set P1,P2,P3..

Don’t set P1,P2,P3,P4,P5
If make a mistake.

Please set it as below:

P1:46 (This hub motor has 46 pcs magnet,can’t set to other,it’s used to display correct speed)
P2:0 (That is low speed motor — without gears inside motor)
P3:1 (With pedal assist)
P4:0 (Start from 0 speed)
P5:15 (24V be 9; 36V be 12; 48V be 15)

Q: Great. After setting this P1, the hub motor works well. Correct, 40mph. Nice electric bike kit.

20 inch 1000W or 1500W front electric hub motor kit

Q: I want to purchase a 20 inch electric bike kit front wheel for my rickshaw, I only ride it with my twin boys they are 3 years old. I obviously don’t want anything with a great top speed I and simply looking for some assistance on hills.From your 1000 watt hub motor wheels listed, it looks like your older design model has a top speed of 30mph so I am thinking that probably has the best gearing not the newer version which show 45mph. The 1500 watt hub motor motor appeals but again same thing only shows with high top speed 45mph…Can you please suggest the best front wheel electric bike kit for me. It has to be 20″ and
has a standard 100mm wide fork.

A: Our new version hub motor also have low speed. Also 1500w motor has low speed.You just tell us what speed would you like, we can do it for you.Our 20 inch front hub motor is fit for 100mm wide fork. Also we have 1500w front.

Q: then I would prefer to order the 1500 watt hub motor, do you offer that in the 20 inch with cast hub or only spokes as can’t see 1500 watt with cast hub listed. I assume the cast hub would be stronger than the spoke version and therefore better for rickshaw.

A: We have 20 inch spokes 1000w & 1500w front hub motor.We have these motors in stock.But caste hub,only 1000w,don’t have 1500 casted hub.

Q: I am still keen to go with the 1500 hub motor but the spoke version is has quite a narrow rim.I don’t suppose you could fit it with a wider rim, so I can use a 2 1/4″ or 2 1/2″ tyre or bigger would be now problem if you have them.Your standard rim states 1.5 – 1.95″ tyre which is a little small I want use a moped tyre because of weight on rickshaw and they are mostly all bigger than your standard rim.
