Compared with double-sided permanent magnet linear synchronous motors (DPMLSM) with long secondary, the short secondary construction also has advantages of high dynamic performance and stable thrust, and is more suitable for the aspect of long-term acceleration. In this paper, magnetic field and characteristic of two different moving-magnet-type double-sided linear synchronous motors were analyzed by using 2D finite element method (FEM). The internal and external permanent magnet motor constructions with the same NdFeB and windings were compared according to flux density and electrical force. It was inferred that internal PM motors can provide the same force with lighter secondary weight and faster response speed.
