Abstract

This paper presents the electromagnetic analysis and experimental testing of a tubular linear synchronous machine (TLSM) with a double-sided axially magnetized permanent magnet (AMPM) mover and coreless stator winding by using semianalytical techniques. Using a simple result based on the finite element method (FEM), characteristics of the TLSM with AMPM can be calculated with the semianalytical method easily. The magnetic flux density in the air gap is obtained by using a magnetic vector potential, a 2-D polar coordinate system, and the results of the magnetostatic calculation based on FEM. Based on these solutions, the electromotive force (EMF) is also determined analytically. Then, 2-D FEM is employed to validate the semianalytical method.l techniques.
