Material handling systems in warehousing applications are used to transport units, which can differ from light bulk material to single piece goods. The drive principle of belt conveyors typically consists of a motor connected to the drive pulley. To move the conveyor belt the entire feed force has to be transmitted by frictional connection over the driven pulley. The allowed tension force of the conveyor belt is a design criterion for the belt conveyor length. To reach large conveying distances, either conveyor belts with high nominal strength or the distribution to multiple conveyors with shorter axis distances is necessary.By using a linear direct drive instead of the driven pulley, the feed force is transmitted over the motor length directly into the conveyor belt. As consequence of the larger force transmission path, this leads to a lower necessary conveyor belt preload as well as the opportunity to use belts with a lower nominal strength due to the reduced peak load compared to the conventional drive principle.During a previous research project funded by the DFG two concepts of belt conveyors driven by a linear motor have been built up as prototypes. Thus, the general suitability for such drive concepts was shown. In cooperation with partners from industry the scientific findings are to be developed further and evaluated based on scenarios with practical relevance.Goal of the research project is to develop new scientific findings for belt conveyors driven by a linear motor in combination with the design and validation of a prototype which can be compared with conventional belt conveyors. By comparison the potential of the linear direct drive principle is to be derived among the cooperation partners. From the view of the cooperation partners the development of the current scientific findings is a high risk for them, because important scientific issues such as e. g. the area of friction caused by normal forces and the guidance system are not solved yet.

仓储应用中的物料处理系统用于运输单位，可以从轻质散装物料到单件货物。带式输送机的驱动原理通常由连接到驱动皮带轮的电机组成。为了移动传送带，整个进料力必须通过从动轮上的摩擦连接来传递。输送带的允许张力是带式输送机长度的设计准则。为了达到较大的输送距离，需要采用高标称强度的传送带或分布在轴距较短的多个传送带上。通过使用线性直接驱动而不是从动皮带轮，进料力通过电机长度直接传递到传送带。由于更大的力传输路径的结果，这导致较低的必要传送带预载荷以及使用较低的标称强度的传送带的机会，由于与传统的驱动原理相比，减少了峰值负载。在之前由DFG资助的一个研究项目中，已经建立了两个由直线电机驱动的带式输送机的概念作为原型。因此，这种驱动概念的一般适用性显示。在与工业界伙伴的合作下，将进一步发展科学发现，并根据具有实际意义的情景进行评价。本研究项目的目标是结合原型机的设计和验证，为直线电机驱动的带式输送机提供新的科学发现，并与传统带式输送机进行比较。通过比较，推导出线性直接驱动原理在合作伙伴间的潜力。从合作伙伴的角度来看，当前科学发现的发展对他们来说是一个高风险，因为重要的科学问题，如法向力引起的摩擦面积和制导系统尚未解决。
