This project aims to clarify the mechanism of power losses in magnetic cores used in the petrol-electric hybrid cars by investigating the relationship between the core losses and magnetic correlation lengths in iron alloys. This project expects to generate new knowledge on the effect of magneto-mechanical interaction on the anomalous core loss in iron based alloys. The intended outcomes include an experimental confirmation of the random anisotropy model, a major theoretical model in nanostructured materials and identification of ideal magnetic domain configurations for lower power losses. These intended outcomes should bring great benefits to the development of low-carbon vehicle technologies for sustainable motorisation in Australia.

本项目旨在通过研究铁合金中铁芯损耗与磁关联长度之间的关系，来阐明油电混合动力汽车用磁芯的功率损耗机理。该项目期望在磁力相互作用对铁基合金中异常铁损的影响方面产生新的知识。预期的结果包括随机各向异性模型的实验确认，纳米结构材料的主要理论模型，以及为降低功率损耗而识别理想的磁畴结构。这些预期的成果应该会给澳大利亚可持续机动化的低碳汽车技术发展带来巨大好处。
