Projects:2019s1-188 Thermal Modelling of Electric Machines with Embedded End-Windings

Introduction

This project involves the development of a thermal model for electrical machines made from soft magnetic composites with embedded end-windings. It will involve the development and simulation of thermal models which is basically an electrical equivalent circuit. The project will include performing steady-state and dynamic thermal tests on components of the electric machine and on the entire electric machine. The outcome will be a thermal model which will allow prediction of the maximum output power of the machine without exceeding thermal limits depending on the operating speed and cooling arrangements for the machine.

Aims

This paper aims to develop a thermal model to perform steady-state and dynamic thermal tests of the electric machine. In addition, another aim of this paper is to use the thermal analysis to predict the maximum output power of the electric machine under the thermal limits.

Motivation

In order to predict the thermal performance of the electric machine accurately, thermal analysis is required to be taken to address the issue which could damage the insulation, result in demagnetized and shorten the lifetime of the machine. This project has the potential to help some electrical manufacturers to produce machines which equipped with larger output power and longer life. In addition, people who are interested in knowing how to predict the maximum output power of machines will benefit from the paper.

Previous Study

Dr. Wen L. Soong, Pro. Nesimi Ertugrul, Solmaz Kahourzade and Yik Ling Lim did a research in 2018 which compared the performance of a soft magnetic composite (SMC) surface PM machine with embedded stator end-windings with a corresponding conventional laminated stator design. They applied finite-element analysis to compare the SMC design with embedded end-windings with the corresponding laminated design.
