- Abstract
- This paper presents the design and implementation of a new electric brush cutter based on the conventional mechanical mechanism of two or four strokes internal combustion engine type brush cutter. The mathematical model of electric brush cutter is presented and the difference between the engine type and electric type brush cutter is made as well. The system controller of electric brush cutter is composed of a speed controller based on a buck converter and the other electronic protection circuits. Some critical drawbacks are often occurred to conventional engine type brush cutter such as high mechanical noise and vibration, unfriendly operating interface, and high using cost during working process. They are very easy to be overcome by the proposed new electric brush cutter. In addition, the designing ideas and working principle of respective circuits included in system controller will be explained gradually. The performances of the proposed electric brush cutter were also validated through extensive experiments and a laboratory scale implementation.
