Abstract

The segmental translator linear switched reluctance motor (STLSRM) is a special type of linear switched reluctance motor (LSRM) that has more output power than its conventional type. Therefore, it can be a good choice for certain applications. Heat is one of the factors limiting the output in machines. Therefore, predicting the thermal distribution of machine is as important as the magnetic design. A comprehensive thermal model is presented based on the lumped parameter approach for STLSRM, which predicts temperature distribution in different parts of this motor, including slot winding, end-winding, stator pole, stator yoke, and the moving part. Considering that the proposed thermal model depends on dimensions and materials used in machine, it can be used for other designs of the STLSRM. The presented thermal model is applied to a typical STLSRM and temperature is determined in its different parts. The simulation results are then compared with the results of 3-D thermal modelling based on the finite element method (FEM) for validation.

分段式开关磁阻电机的集总参数热模型

分段转换线性开关磁阻电动机是一种特殊类型的线性开关磁阻电动机，其输出功率比传统的开关磁阻电动机大。因此，对于某些应用程序，它可能是一个很好的选择。热是限制机器输出的因素之一。因此，预测机器的热分布与磁设计一样重要。基于集总参数法建立了STLSRM的综合热模型，该模型预测了该电机不同部件的温度分布，包括槽绕组、端绕组、定子极、定子yoke和运动部件。考虑到所提出的热模型取决于机器的尺寸和所用材料，可以用于STLSRM的其他设计。将所建立的热模型应用于典型的STLSRM，并确定了其不同部位的温度。然后将仿真结果与基于有限元法(FEM)的三维热模拟结果进行了比较，以验证其有效性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
