Study On Sensor-less Motor Bike

In the recent years,the motorbike has rapidly developed with the improving of living Chinese people. Because of air pollution of internal combustion engine the local governments of different cities in China come on a lot of rules of law to restrict the use of combustion engine and then to promote the environment protection. To replace the motorbike with a short green transportation has become some nations' economic and social issue.This paper deals with an electric motor driven bike (EB) and its control stratagem. Without fail,EB is very helpful to environment protection. Nevertheless EB has its disadvantages,especially the too weak continuous run distance. Except the battery problem,the efficiency of the whole system is also one of the most important problems to be solved. A permanent brush-less and sensor-less DC motor and its control set are specially designed for this developed EB. A study on control stratagem and electronic resorts are given in this paper.A microchip PIC16C74 used as CPU and corresponding software developed by author is introduced in this control system. The experiments of the prototype show that the performance,including system efficiency,noise,spark,maintenance-free and its cost are obviously improved. It may be expected,that this EB driving system has really huge market potential.
