如今，金属成形机中的金属板的循环进给是通过机械辊式或夹式进给器实现的。有限的进给力以及受限的动力学和由于机械接触而损坏片材表面的可能性通常限制整个冲压线的生产率。在IFUM，基于异步直线电机开发了一种新的非接触式进给系统，利用该系统，可以通过电磁力非接触地向导电金属板施加高进给力。在本文中，给料机的操作特性取决于板材的属性，也对他们的几何形状。根据模拟和实验，与使用辊式给料机的情况下的可达力相比，给料力可以显著增加。
Today, the cyclic feeding of sheet metals in metal forming machines is realized by means of mechanical roll or grip feeders. The limited feeding forces as well as the restricted dynamics and the potential for damaging the sheet surface as a result of mechanical contact often restricts the production rate of the entire press line. At the IFUM, a new contactless feeding system has been developed, based on the asynchronous linear motor, with which high feeding forces can be applied to the electrically conductive sheet metal contactless by means of electromagnetic forces. In this paper, the feeder’s operation characteristics depending on the sheet material properties and also on their geometry are presented. According to simulations and experiments the feeding forces could be significantly increased in comparison to reachable forces in case of using roll feeders.
