项目摘要

In conventional permanent magnet synchronous machines, the magnets (e.g. neodymium-iron-boron-(NdFeB)-magnets) are on the rotating part (rotor), where only a limited cooling of the magnets is possible. Thus, typical continuous operating temperatures in the magnets are at 150 °C - 180 °C. So high continuous temperatures are only possible with NdFeB-magnets with additives (e.g. dysprosium) or samarium-cobalt (SmCo) must be used. SmCo-magnets have a lower remanence flux density and are more expensive than NdFeB-magnets, but also the dysprosium increases the cost of NdFeB-magnets significantly. Alternatively, the magnets of the machine can be mounted in the stationary part (stator). Due to this, the magnets are close to the stator cooling circuit and the temperature in the magnets can in general be kept below 100 °C. Therefore, cheap and highly remanent magnets with less or even without dysprosium can be used. The rotor of those machines is winding- and magnet-free and robust. In the stator, inexpensive tooth coils can be used, but the constructive fixation of the magnets must be designed rationally. Three different topologies with stator mounted magnets have gained increased attention in recent years: Doubly-Salient-Permanent-Magnet-(DSPM)-Machine, Flux-Reversal-Machine (FRM) and Flux-Switching-Permanent-Magnet-(FSPM)-Machine. Existing investigations suggest that the FSPM-Machine achieves the highest torque densities at the same thermal utilization. A goal of this project is the comparison of the three machines for a given performance requirement and to document quantitatively the expected advantages of the FSPM-Machine. Another aim of the project is to develop a methodological approach for the design of Flux-Switching-Machines in the power range up to 150 kW as high-torque drives for the lower and medium speed range up to 3000 /min. The electromagnetic, thermal, mechanical and constructive design criteria should be worked out in coordinated steps and validated by measurements using a prototype machine. A prototype of the Flux-Switching-Machine should be compared with a comparable, at the Institut für Elektrische Energiewandlung available, conventional PM synchronous machine with regard to the achievable electromagnetic utilization, efficiency, converter utilization and the performance in case of a failure (such as a short circuit).From that, general applicable design rules for Flux-Switching-Machines should be derived and the advantages and disadvantages of this type of machine should be emphasized compared to conventional machines.

在常规的永久磁铁同步机中，旋转部分（转子）上只有磁铁（例如，新近铁 - 孔 - 孔（NDFEB） - magnets），只有有限的磁铁冷却。这通常在磁铁中的连续工作温度为150°C -180°C。只有使用添加剂（例如疾病）或samarium-cobalt（SMCO）的NDFEB-MAGNET才能使用高连续温度。 Smco-Magnets具有较低的Remanence通量密度，并且比NDFEB-Magnets昂贵，但疾病障碍也大大提高了NDFEB-MAGNETS的成本。或者，机器的磁铁可以安装在固定部分（定子）中。因此，磁体靠近定子冷却电路，并且磁体中的温度通常可以保持在100°C以下。因此，可以使用廉价且高度浪漫的磁铁，甚至没有降低症状。这些机器的转子是无缠绕和磁性且健壮的。在定子中，可以使用廉价的牙齿线圈，但是磁铁的建设性固定必须是理性设计的。近年来，带有定子安装的磁体的三种不同拓扑已引起了人们的注意：双重降低 - 永久性磁铁 - （DSPM） - 机器，通量 - 逆转 - 机器（FRM）和通量转换 - 磁盘 - 过时的 - 永久性 - 磁性 - 磁性 - 磁铁 - 磁铁 - （FSPM） - machine-machine。现有的研究表明，在同一热利用率下，FSPM计算机达到了最高的扭矩密度。该项目的一个目标是将三台机器以给定性能要求进行比较，并定量地记录FSPM机器的预期优势。该项目的另一个目的是开发一种方法学方法，用于在功率范围内设计通量开关机器的方法，高达150 kW，作为高速驱动器的较低速度和中速范围，高达3000 /min。电子，热，机械和建设性设计标准应以协调的步骤制定，并通过使用原型机的测量进行验证。应将通量开关机器的原型与可比的fürElektrischeEnergiewandlung Instrable的可比性进行比较与传统机器相比，应强调这种类型的机器的优势和缺点。
