Optimization of Force-to-Weight Ratio of Ironless Tubular Linear Motors Using an Analytical Field Calculation Approach

In this article, an optimization of an ironless permanent magnet tubular linear synchronous motor (PMTLSM) for applications in human support systems is presented. For this application, a bendable and light-weighted motor design is desired. For the computation of the motor force, an analytical method is established. The method is validated by the finite element (FE) analysis and utilized for the optimization of the motor geometry regarding the force-to-weight ratio.
