| Abstract: | It introduces the motor- driven system of the electrical bicycle. Based on the AVR single chip, through modulating the dutyratio of PWM wave, the speed of the electrical bicycle can be well controlled. The research is focused on the phenomenon of overcurrent, overload and abnormal operation of the motor dur- ing begining. It puts forward the method of overcurrent detecting and protecting. The experimental results show that the method has good ability. |
