Abstract
En 中文
Approximately 25% of all electricity worldwide is consumed by pumps, compressors, and blowers in industrial applications. High-speed electric machines based on magnetic suspension technology present a significant opportunity to improve the efficiency of these drivelines, thus reducing total energy consumption, costs, and pollution levels. However, a major challenge in adopting the high-speed drivelines in industrial applications lies in their implementation. The design lead time for such machines typically spans years, whereas an ideal time-frame would be mere weeks. This study presents a systematic multidisciplinary design process for thrust active magnetic bearing to accelerate design work. By structuring the design steps in a precise order, automation can be integrated to develop the design space, which can then be directly utilized in the system level design analysis. In practice, when another design area is modified, a thrust bearing design that fulfils the overall design requirements can be automatically updated from the design space. Consequently, non-viable solutions are directly excluded, reducing the iterative nature of high-speed machine system design. Part I of this paper details the methodology of the multidisciplinary design process, while Part II illustrates the application of the proposed design method using a one-megawatt high-speed electric machine for a heat pump compressor.
