This paper deals with analytical and experimental study of permanent magnet linear synchronous machines with horizontally magnetized permanent magnets. Six subdomains are defined as analysis domains considering end effects, slotting effects, and flux pass iron poles. The governing equations for each domain are derived from the Maxwell equation and the constitutive relations in electromagnetic theory, and the second-order differential equations are calculated by using the Sturm-Liouville theory. By applying the boundary conditions, analytical solutions in each area are derived, and electromagnetic performance and generating characteristics can be predicted based on the derived analytical solutions. The proposed analytical method is validated by comparison with finite element and experimental results.This paper deals with analytical and experimental study of permanent magnet linear synchronous machines with horizontally magnetized permanent magnets.
