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.

仓储应用中的材料处理系统用于运输单元，这可能从灯泡材料到单件商品不同。皮带输送机的驱动原理通常由连接到驱动皮带轮的电动机组成。为了移动输送带，必须通过驱动的皮带轮上的摩擦连接来传播整个进料。传送带的允许张力力是皮带输送机长度的设计标准。为了达到较大的输送距离，必须具有高标称强度的输送带，或者必须分配到轴距离较短的多个输送机上。通过使用线性直接驱动而不是驱动的皮带轮，将进给力直接传递到电动机长度上，直接传输到输送带中。由于较大的力传输路径，这导致了较低的必要输送带预紧力，并且有机会使用与常规驱动原理相比，由于峰值负载的降低而具有较低的名义强度的皮带。在DFG的先前研究项目中，由DFG提供了两个由线性电动机驱动的皮带输送机的概念，该概念是由线性电动机构建的。因此，显示了此类驱动器概念的一般适合性。与行业的合作伙伴合作，科学发现将进一步开发，并基于具有实际相关性的方案进行评估。研究项目的目标是为线性电动机驱动的皮带输送器开发新的科学发现，并结合与常规带传送器相比的设计和验证。相比之下，线性直接驱动原理的潜力将在合作伙伴之间得出。从合作伙伴的角度来看，当前科学发现的发展是对它们的高风险，因为重要的科学问题（例如e）。 g。正常力和引导系统引起的摩擦面积尚未解决。
