摘　　要：介绍了用直线电机直接驱动冲压机工作的基本原理、结构、性能以及它的控制方法。和传统式机械冲压机相比，它具有结构简单、体积小、重量轻、制造周期短、成本低、控制方便、噪声低和节能等优点。目前已研究完成了５０ｋＮ以下的科研样机，通过了省级鉴定并获得了多项专利，现已投入小批量生产，效益显著。This paper deals with the new punching machine driven by a linear induction motor (LIM).The fundamental principle,construction,performance and application are described in this paper.Comparing this new model machine with its traditional form,the LIM driven punching machine has many great advantages,such as,simple construction,small size and weight,low production cost,short production time,easy to control,low noise and considerable energy saving.Now the authors have accomplished the research project and manufactured several prototype machines with rated forces less than 50kN,which have passed the provincial appraisal and have gained patents.Now we have got a number of grants from the Chinese National Foundation of Science and several companies which make us enable to design a new prototype machine with rated force more than 100kN.
