Abstract

This thesis focuses on design and analysis of SynRM (synchronous reluctance motors) Several different electric steels are used in the design of SynRM including ultra-thin laminations This thesis aims to develop a process for design and analysis of SynRMs with different materials in order to maximize the advantages of these materials and achieve low iron loss and high efficiency for the designed SynRM This thesis consists of two major parts First a design method for SynRM is proposed where the d-q-axis inductance analysis and design procedure of flux barriers are developed The objective is to achieve a rotor design such that the coupling between the d- and q-axis inductances can be minimized and the motor efficiency can be improved In the second part the electric steels are employed in SynRM designs and their performances are analyzed In order to take advantages of these different materials the motor designs are modified to reduce iron loss increase efficiency and achieve a cost-effective design The benefit of using specific high performance materials is then evaluated The methods developed in this thesis are verified by simulations for a 1 kW SynRM prototype The advantages of using ultra-thin electric steel for SynRM through the developed design methods are verified Experiments are also conducted for comparison
