Finite-element modelling of electrodynamic processes as a method of determining the optimal number of turns on a winding of a machine press electromagnetic motor

Abstract

Abstract This article presents the optimization problem solution employing the methods of finite-element modelling of electrodynamic processes for choosing the number of winding turns in an electromagnetic motor driving a machine press. The subject of the investigation is a new methodology for identifying optimization solutions to a differential equation describing the finite-element model of the electromagnetic motor and analyzing its calculated dynamic characteristics. The object of the investigation is a cylindrical construction of an electromagnetic motor with two working gaps and a combined composite armature. The basis of the finite-element model is a computational scheme and a software package created at the Department of Applied Mathematics at Novosibirsk State Technical University. It is illustrated that the applied computing apparatus and the software package allow performing an accurate search for the optimal number of turns on a winding of an electromagnetic motor at the design stage with due consideration for the required geometric parameters and the magnetic properties of the structural materials employed for obtaining the maximum final velocity of the armature in motion.
