Optimal Design Strategy for a Novel Linear Electromechanical Actuator

概要

論文の詳細を見る
The paper presents a design procedure for a novel linear electromechanical actuator from a basic concept to a prototype with optimized characteristics. The actuator itself is a complex electromechanical system combining features of the active magnetic bearing (suspended mass in the order of 0.3kg) and the linear Lorentz actuator (long stroke range—50mm). During the design procedure the analysis and selection of the magnetic materials are carried out. A parametric search with respect to main design variables is performed. Special attention is paid to the development of the analytical model that is an essential tool for future optimization. A design procedure leads to modifications in dimensions and coils arrangement. An improved prototype is designed and manufactured. The results obtained by the finite element method (FEM) and analytical modeling are validated by measurements.
