Research on Characteristic of a Novel Permanent Magnet Linear Motor

Abstract

To meet the steep demand of small volume and light weight, this paper completes the research on characteristics of a novel permanent magnet linear motor, following the principle of high power density and high efficiency, and finally realizes energy conversion efficiently. The reasonable magnetic circuit structure and electromagnetic design are adopted to design and develop novel permanent magnet linear motor prototype. The contrast analysis of axial magnetic flux structure and Halbach structure is implemented, and then the best solution of design size and performance is completed. Also the prototype is developed and verified. The test results show that the prototype of the permanent magnet linear motor can meet the requirement of high power density and high efficiency. The novel permanent magnet linear motor also has a higher dynamic response and higher thrust/weight ratio.
