Design and Optimization of Small Induction Machines for Pump Applications

This paper delineates the process of design, modeling, and multi-objective optimization of a compact induction machine tailored for pump drive applications. The primary objective is to enhance critical performance parameters-specifically efficiency and $t$ hermal $c$ haracteristics-while a dhering $t o$ manufacturability constraints prevalent in industrial settings. A systematic methodology is proposed, encompassing both electromagnetic and thermal modeling, alongside an optimization strategy utilizing the Non-Dominated Sorting Genetic Algorithm II. Furthermore, the study encompasses the development of prototypes and their subsequent experimental validation, ensuring that the final design m eets established performance criteria and practical implementation standards. This research underscores the potential for significant energy savings through optimization, even in low-power electrical machines that are often neglected regarding efficiency enhancements.
