Desenvolvimento de um Atuador Eletromagnético Linear Hexagonal com Alta Densidade de Força

Abstract

This work presents the study and development of a hexagonal linear electromagnetic actuator designed for high force density with an industrial focus (ease of machining and manufacturing). The chosen topology is a synchronous permanent magnet configuration with a moving armature (stack of disks made of Somaloy Prototyping Material - SPM and Copper), where both the armature and the field (array of Neodymium-Iron-Boron Grade N42SH permanent magnets and SAE 1020 steel ferromagnetic back-iron) have six flat faces. The proposed model is discussed in terms of requirements, materials, and feasibility. The validation of the proposed model is carried out through numerical analysis, where values of magnetic induction, electric current density, induced voltages, and axial force demonstrate the effectiveness of the proposed topology.
