Abstract: The linear motor is a electromagnetic machine which can directly convert the electric energy to mechanical energy. It is well popular in the industrial application. The condition of its structural crafts, controlling means and strategy direct affect the application and development. The article presented the analysis of characteristics and working principle of the permanent magnet linear synchronous motor (PMLSM) according to the characteristics of PMLSM control. It also discussed the development of new PMLSMs overview based on the relevant literature home and abroad about PMLSM. At the same time it described the advantages and disadvantages of various controlling technique according to each new controlling means.
Key words: permanent magnet; linear motor; controlling strategy
