Characteristic Analysis of Moving Magnet Type Double-Sided Linear Synchronous Motor

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.

The Analysis of Permanent Magnet Double-Sided Linear Synchronous Motor With Perpendicular Arrangement

In this paper, a new linear synchronous motor-permanent magnet double-sided linear synchronous motor with perpendicular arrangement (PMDLSM), was proposed. This motor was designed to account for the drawbacks of conventional linear motors, such as the problems with normal force and end effects. It was designed by analyzing the detent force and the thrust of different models, and optimizing the design variables of the machine. The characteristics of the perpendicular PMDLSM were analyzed by finite element method, and a comparison of the results was made in the experiments.
