Increasing efficiency of linear stepper electromagnetic engine

Abstract

The rise and sustainable development of mining enterprises are inseparably linked with the search for and the introduction of progressive methods of intensification of operations and processes, among which pulsed or vibrational methods that allow one to concentrate and efficiently expend energy occupy a significant place. In the development of characteristic technologies, an important role belongs to power discrete drives with linear electromagnetic engines that allow one to abandon motion transducers and especially successfully compete with traditional electric engines in machines and installations where reciprocating movements of the working element along a linear trajectory are necessary. In this paper, we propose a new functional arrangement of a linear electromagnetic engine with a through axial channel and an integrated clamping mechanism and a calculation of the clamping force of the ball clamps in a stepped linear electromagnetic engine. Taking into account the required driving force of the working element, it is possible to calculate the necessary tractive force created by the armature during its working stroke under the action of electromagnetic force, and to select the corresponding linear electromagnetic engine for this actuator drive.
