The paper deals with the analysis and optimization of spinning electrode designed for the nanofiber spinning method using an alternating electric current. The optimization was based on the simulation of distribution of electric field according to the shape of the spinning electrode by using the finite element method. The intensity of electric field has a major influence on the electrospinning and subsequently on the resulting structure. The aim of the optimization was to reach uniform distribution of electric field on the electrode surface by changing the number of design parameters. Based on these analyses, a new shape of the spinning electrode was designed, which offers uniformity of the electric field intensity around the whole operative surface of the spinning electrode and provide the same physical conditions which are important for the electrospinning. This leads to the electrospinning stabilization, which affects the quality of the resulting nanofiber structure.Keywords: Electric field, electrospinning, spinning electrode, electrostatic analysis
