Abstract
Motorcycle as modern transport has the virtue of convenience,fast speed.But with the increase in motorcycle ownership,urban environmental pollution and energy shortages are becoming increasingly serious,taking into account the current situation in China,the development of electric motorcycles has important environmental significance.And flexible,lightweight,"zero emission",low-cost advantages will enable electric motorcycle car quickly gained popularity.
This topic is about how electric motorcycle control system works,According to the project, PIC16F72 MCU produced by Microchip Company has been selected. The design of hardware including power circuit, hardware protection circuit, electronic commutate circuit .There are three hall sensors for the positon of the rotor,according to the position of the rotor and PWM(pulse width modulation)control signals,the electronic commutator works.The software was designed following the principle of modulation and structured programming and using PIC C language. Less voltage protection, current excessive protection are designed to reinforce the system. Micro controller-based design of this system has a good operating performance, high reliability, upgrade and updating and easy to provide a foundation for subsequent research.
