The controller of electric motorcycle is not only the component to control the motor speed, but also the core of the electrical system of electric motorcycle. It is designed with multiple protection function control system, with undervoltage current limiting or overcurrent protection function.

We know that electric bicycle is a special bicycle with battery as auxiliary energy and two wheels,which can realize manual cycling.Electric or electric assisted function.Although it has the appearance characteristics of ordinary bicycle(even the appearance characteristics of motorcycle)But the main thing is that it is an electromechanical personal vehicle based on ordinary bicycles.It is equipped with motor,controller,battery,handle,brake handle and other operating components and display instrument system.Different types of vehicles have different battery placement positions and controller forms.

Friction wheel drive: the friction wheel on the driving machine directly acts on the rubber tire of the rear wheel and drives through friction. The utility model has the advantages of simple structure and low cost, but the rotation efficiency is low, the energy consumption is large, the friction loss of vehicle tires is large, and it is easy to slip in rainy days.

China's electric bicycles have always been in the leading position in the world in the application of torque sensor technology and integrated circuit controller technology.Powerful enterprises have applied integrated electronic and digital technology to controllers,motor valve control,charging control and other components.Intelligent electric bicycles will be the commanding heights of future development.

Electric bicycle refers to a mechatronic personal vehicle with battery as auxiliary energy and installed with motor,controller,battery,handle,brake handle and display instrument system on the basis of ordinary bicycle.Its main components include the following.

Electric motorcycle is a kind of electric vehicle, which uses battery to drive motor. The electric drive and control system is composed of drive motor, power supply and motor speed control device. Other devices of electric motorcycle are basically the same as those of internal combustion engine.
