Design and Optimisation of a Moving-Iron Linear Permanent Magnet Motor for Reciprocating Compressors using Finite Element Analysis

The paper describes design and optimisation of a tubular moving-iron linear permanent magnet motor for reciprocating compressor using finite element. The four leading design parameters are optimised individually. To validate the process reaches an optimal design, two leading parameters are varied simultaneously. This is due to one parameter may
influence other parameters. The linear motor is aimed to
produce 88.5 W output power which is enough to operate
household refrigerator compressor system. . To reduce material and manufacture cost, Strontium Ferrite and soft magnetic composite are used in this design.
