Flux Switching 전동기의 토크 특성 해석

Abstract

Flux Switching Motor(FSM) has advantages: it consists of simple control circuits; it has simple structure; its efficiency is high; it costs less to produce due to mass production. But it also has disadvantage such as noise. With the development of power electronics technology, Flux Switching Motor draws researchers' attention. Although the Finite Element Analysis has been used for a long time in the field of motor analysis and design, it takes longer to analyze than other methods. On the other hand, Magnetic Equivalent Circuit Method, one of the other motor analysis methods, is not capable of considering a torque harmonic in the air gap. But Winding Function Theory considers a torque harmonic in the air gap and can be analyzed in a very short time. The torque characteristics of Flux Switching Motor with salient rotor by using Winding Function Theory have been recently researched. In this paper, torque characteristic analysis of Flux Switching Motor based on Winding Function Theory is described. Two method analyzing torque characteristic of Flux Switching Motor was used to compare Finite Element Analysis with Winding Function Theory. As a first method, Maxwell program was used to analyze Flux Switching Motor based on Finite Element Analysis. As a second method, Matlab program was used to analyze torque characteristic of Flux Switching Motor Flux Switching Motor based on Winding Function Theory.
