In the micro-stamping technology, roll-feeding systems are currently used to transport thin metallic foils. The rolls are pressed onto the material with so much pressure, that a force-locked, stick-slip-free connection is established. The high load can have negative influence on the quality of the material surface, or cause material deformation respectively. Lower contact force between the roll and the material on the other hand can result in stick-slip at highly dynamic movements. This can only be avoided by lowering the feed rate. In the proposed research project a new contactless feeding principle will be discovered to transport thin metallic foils to avoid the above mentioned disadvantages. The principle is based on the asynchronous linear motor. Feeding force will be achieved through contactless introduction of Lorentz-Force in the material, which eliminates the above mentioned disadvantages. The principle will be modeled in an FEA model, which will be used to perform studies on the feasibility of this principle. A demonstrator will be built to validate the results of the FEA study.

在微冲压技术中，滚送系统目前主要用于输送金属薄片。辊子以很大的压力压在材料上，从而建立了一个力锁定的无粘滑连接。高载荷分别会对材料表面质量产生负面影响，或引起材料变形。另一方面，轧辊与材料之间较低的接触力会导致高动态运动时的粘滑。这只能通过降低进给速度来避免。在本研究项目中，将发现一种新的无接触馈送原理来输送薄金属箔，以避免上述缺点。其原理是基于异步直线电机。进料力将通过在材料中非接触引入洛伦兹力来实现，从而消除了上述缺点。该原理将在FEA模型中建模，该模型将用于对该原理的可行性进行研究。将建立一个演示器来验证有限元分析的结果。
