关于客户
EVR Motors Ltd. 是电动汽车行业的新参与者。该公司总部位于以色列，设计和开发经济高效的径向磁通永磁 (PM) 电机，适用于可再生能源和汽车电气化等一系列电力转换应用。 EVR成立于2012年，最初开发风力发电机专利。然而，当公众口味青睐电动汽车时，他们调整了路线图，然后开发了一种名为 TS 的创新型电动机 – RFPM（梯形定子径向磁通电动机），该电动机基于新的专利技术，可提供卓越的功率和扭矩密度，并且产量较低成本。
挑战
向电动汽车的转变给汽车行业带来了巨大的压力，要求其开发更可持续、更实惠的交通解决方案。这导致人们热衷于产品电气化，并与与内燃机车型性能相匹配的电动汽车竞争。 EVR Motors Ltd. 是一家以色列公司，致力于设计和开发经济高效的径向磁通永磁 (PM) 电机，该公司面临着独特的挑战。几十年来，电动汽车电机一直使用相同的拓扑进行优化，称为径向磁通永磁电机拓扑 (RFPM)。然而，EVR 选择采取不同的方法。他们没有优化现有技术，而是决定发明一种新的拓扑结构，并为电动汽车行业开发一种全新类型的电机，称为梯形定子 RFPM 拓扑结构。由于 EVR 拓扑的基础不同于其他众所周知的电机拓扑，因此多物理场和优化工具的使用非常重要。因此，团队需要一个可靠、强大的模拟工具。
解决方案
为了寻求强大而准确的电磁和机械仿真工具，EVR Motors 选择了 Altair® FluxMotor®、Altair® Flux®、Altair® SimLab® 和 Altair® HyperMesh®。这些工具是 Altair 完整的电机设计解决方案的一部分，用于在原型设计之前对其电机进行仿真。电机开发涉及大量设计迭代，以满足所有电磁和 NVH 要求。 EVR 使用 Altair 工具，特别是高度灵活的 Flux 软件来改进模拟，使模拟变得更加准确，并提供接近他们实际构建的真实原型的结果。如今，EVR 的模拟精度已达到约 90%，但他们的目标是将其提高到 95-96% 的更高精度。尽管 Altair 的电磁设计是全新的，并且与当今存在的所有产品都有很大不同，但 Altair 的解决方案帮助 EVR 应对这一挑战，最大限度地减少原型数量，同时满足所有要求并节省时间。

Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.
