Thrust Performance

The cylindrical permanent-magnet linear motor (PMLSM), as a linear driving device, produces the electromagnetic force to cause linear motion through the electricity directly and does not need additional mechanical conversion devices to transform rotation to linear motion. This paper calculates the electromagnetic distribution and force of two kinds of cylindrical PMLSM by ANSYS, and compares and analyzes their thrust performance. It is concluded that a radially magnetized cylindrical PMLSM is suitable for the applications requiring smaller speed variation while an axially magnetized one possesses a bigger thrust and thrust variation yet.

This paper concerns the analysis and optimization of a permanent magnet linear synchronous motor. The motor consists of moving ironless coils and a stator with novel double-side Halbach array. Some characteristics of the linear motor were investigated. The dimensions of the novel Halbach magnet array were optimized. The optimization was verified by finite element method.

Permanent Magnet Linear Motor

Abstract The calculation results of the static field parameters for permanent magnet linear synchronous motor have been presented in this work. The influence of the construction temperature on the parameters has been analyzed mathematically. Models for magnetic and temperature fields determination have been formulated. Two kinds of permanent magnets (NdFeB and SmCo) have been considered. The distribution of the thermal field has been obtained using the finite element method (FEM).
