A New Electric Brush Cutter
Author:
Abstract: To integrate power electronic control technology into the most mechanical mechanism of conventional internal combustion engine type has made it possible to design and implement a new electric brush cutter with blade rotation speed control and circuit protection functions. The mechanical power source of tradition mechanical grass cutter is based on a two or four strokes petrol engine. To obtain some very attracting advantages such as low vibration and acoustic noise, free of air pollution and low using cost, a DC motor is used as the mechanical power source of new electric type brush cutter. In addition, a Li-ion battery and electronic control board designed for DC motor speed control and circuit protection purposes were included as well. Designing ideas and the working principle of respective circuit in electronic control board will be explained. The performances of the proposed electric brush cutter were validated through extensive experiments and a laboratory scale implementation.
