Lift Force Analysis in a Controlled — PM LMS Maglev Carrier
Conference paper
Abstract
The lift force in the controlled permanent-magnet (PM) linear synchronous motor (LSM) Maglev carrier is theoretically evaluated by using the analytical formulas previously proposed by one of the authors and numerical finite-element method (FEM). The proposed theory and the FEM analysis are verified from comparing the calculated results with measured values in the experimental carrier designed on a basis of our analytical formulas.
