ABSTRACT
This paper presents a new linear model that allows for accurate prediction of cutting forces and battery runtime for jigsaws. The electromechanical model is based on Lagrangian equations of the second kind and an energy-based approach, taking into account mechanical and electrical dynamics, as well as the oscillatory motion of the sliding mechanism. The simplified linear model with an optimized damping factor, validated with experimental data in the MATLAB Simscape environment, showed an extremely low relative error compared to real measurements, while providing excellent computational efficiency. The results highlight the industrial applicability of the model in improving energy efficiency, extending battery life, and optimizing performance. The methodology can also be applied to other systems characterized by cyclic force effects, where accurate simulation and performance estimation are critical.
