Introduction

We are professional do e-bike kits business for many years for the customers all over the world, and have met so many troubles, with these troubles, we have much experience on e-bike kits today.

Our e-bike kits are easy to install and allow you to convert your standard bicycle into an fun and eco-friendly e-bike. Since every model is different and components will vary, it's your responsibility to determine the best way to install an electric bike kit on your bike. Although most of the steps are similar from install to install, we have instructions can help the customers to convert their bicycle.

We have build the Europe after-sale service center in Europe to repair the parts including motor, batteries, controller etc, also for the whole ebikes repairing. As one of the pioneer seller for ebikes in china, BTN aims to master clean energy technique, and develop energy-saving and environmental-friendly ebikes.

Q:Brushless motor brushless motor! Urgent. Professionals to help answer!: It can be said: the controller is the core of electric vehicles, it is the main component of driving motor, the general controller has a maximum output current of this parameter, you can see, if your controller is 48V 20A, which means that your controller can provide the maximum current of the motor is 20A, if the big words the controller will appear, to protect. So the controller chooses the ampere as much as possible so that the ability of climbing is strong.

Q:How many motors are there?: According to the general form of electric motor electric motor to points, can be divided into brushless motor and brushless motor two categories; according to the mechanical structure of the motor assembly points, generally divided into "teeth" (high speed motor, need to go through the gear) and "toothless" (without motor torque output any reduction in two categories).

Q:What's the meaning of dual mode intelligent brushless motor controller for electric vehicle?: Main functional features:There is no Holzer dual compatible mode (dual function): in the normal state, the controller can automatically identify the motor commutation angle, Holzer phase and motor output phase, as long as the power line, the controller turn line and brake line is not wrong, the automatic recognition of input and output mode of motor and motor can, in Holzer not working (bad) condition, the controller will automatically sense the abnormal situation, to abandon the Holzer startup mode, automatically switch to Holzer free state, so that the electric car will not damage normal riding for Holzer.

Q:The electric motor is broken. What's the reason?: 1.5 、 the no-load / load speed ratio of the motor is greater than twoTurn on the power, turn the handle, make the motor rotate at high speed and no load, more than 10s.When the speed of the motor is stable, the maximum speed of the motor is measured at N1 with a hand-held speed / speed meter.In the standard test conditions, traveling above 200m distance, began to measure the maximum load speed of motor N2.Load / no-load speed ratio of =N2 / N1When the motor no-load speed / load ratio is greater than 1.5, indicating the motor magnet demagnetization has been quite severe, should replace the motor set inside the magnet, in the process of practical maintenance of electric vehicles in general is the replacement of the entire motor.

Q:How to assemble and disassemble the electric motor?,: Electric vehicle battery exchange agency for your answer: first remove the motor, unscrew the screws with the flywheel side (side, popular point is that there is no motor without the other side of the line, unscrew the screw with the flywheel side) to ensure that the motor is fully unloaded, and then hold the ends of motor in symmetrical, looking for a relatively thick point (wood to ensure that the thread of central axis is not destroyed), no motor line side down knock on wood, force must be steady, accurate and relentless. Bang bang, the cover is opened. Then you can take out the rotor. When installed, in turn, you can use the screws symmetrically fastened on it. Welcome to join the battery exchange of electric vehicles. If you are satisfied with the answer, please give the group a bonus. Thank you!

Q:Electric cars are generally divided into several kinds? What is the difference between the motors?: Electric vehicle has two kinds of brushless brush, brush electric vehicles, because of the need to use carbon brush, so the motor in use after two or three years to replace the carbon brush, some not too convenient, and brush the efficiency of the electric vehicle is relatively poor, climbing ability is poor. The efficiency of Brushless high, climbing or.

Q:The electric bicycle turns and turns the motor. It doesn't move. What's the matter?: The electric bicycle turns and turns the motor. It doesn't move1, bad line contact, it is likely to turn the line of a place of high voltage caused by a string.

Q:Electric motor five fine wire what role?: The five thin line is the Holzer line. It is also the induction line of motor starting. It saves electricity and starts smoothly. It does not hurt rotor and noise. Do not use five thin lines, start unstable, and sometimes reverse

Q:Holzer principle of electric locomotive motor: Transfer Hall signal to the controller, the controller through the thick line (not hall line) to the power supply, motor coil motor rotation, magnet and coil (precisely winding on the stator coil, in fact, the hall is usually installed in the stator) to rotate, Hall position signal induces a new, thick line the controller to change the direction of the current power supply to the motor coil,

Q:The electric vehicle operation, the motor suddenly belch belch two times, then do not go, I opened the electric car controller, well, turn the fuse is good, good: Do you have a multimeter?. In addition, turn the line in order, not wrong. Only after rough red, thick black, the switch and the motor phase / Holzer. Don't pick it up
