滾珠絲杠在機床行業的普遍應用，推動了加工機床行業的快速發展，但機械式傳動的局限性，已無法應對日益高速化、化切削的發展趨勢。直線電動機式就是在這種趨勢的需求下產生的一種高速傳動方式，非常是機床的高速傳動發展跨上一個新臺階。德國作為世界先進機床的先驅，20世紀80年代就開始了高速銑削和車削技術的研發。

The widespread application of ball screws in the machine tool industry has driven the rapid development of the machining machine tool industry. However, the limitations of mechanical transmission make it impossible to cope with the increasing trend of high-speed and efficient cutting. The linear motor type is a high-speed and efficient transmission method that has emerged under the demand of this trend, especially in the development of high-speed transmission of machine tools, which has reached a new level. As a pioneer of advanced machine tools in the world, Germany began the research and development of high-speed milling and turning technology in the

當進給速度為20m/min時，其輪廓精度可達0.004mm。美國的Ingersoll公司緊接著推出了HVM-800型高速加工，大進給速度達到75.20m/m i n。

When the feed speed is 20m/min, the contour accuracy can reach 0.004mm. Ingersoll Company in the United States immediately launched the HVM-800 high-speed machining center, with a large feed speed of 75.20m/min.

1996年開始，日本相繼研制成功采用直線電動機的臥式加工、高速機床、超高速小型加工、超精密鏡面加工機床、高速成形機床等。從此以后，直線電動機在高速數控機床的應用如雨后春筍般地迅速發展起來。近十年來，世界上各工業發達國家紛紛投入巨資，大力研究、開發成功不少直線電動機驅動的高速數控機床，并逐漸有搶占傳統滾珠絲杠市場的態勢。

Since 1996, Japan has successively developed horizontal machining centers using linear motors, high-speed machine tools, ultra high-speed small machining centers, ultra precision mirror machining machines, high-speed forming machines, etc. From then on, the application of linear motors in high-speed CNC machine tools has rapidly developed like mushrooms after rain. In the past decade, various industrialized countries around the world have invested heavily in researching and developing many high-speed CNC machine tools driven by linear motors, and gradually have a trend of seizing the traditional ball screw market.

直線電動機加工在國外的寶馬、通用等汽車公司已經有成熟的應用，在國內上汽通用、東風雪鐵龍、昌河鈴木、海馬汽車等也有整線的應用實例。本文從技術分析和應用實例上進行了直線電動機和滾珠絲杠驅動加工的對比。圖1為Comau Urane25直線電動機高速加工。

The linear motor machining center has mature applications in famous automobile companies such as BMW and General Motors abroad, and has also been applied in whole lines in China, such as SAIC General Motors, Dongfeng Citroen, Changhe Suzuki, and Haima Motors. This article compares the linear motor and ball screw driven machining centers through technical analysis and application examples. Figure 1 shows the Comau Urane25 linear motor high-speed machining center.
