Abstract

Recently, cost of rare-earth magnets has been raised, because rare-earth magnets are monopolized and the export is also regulated in China. For this reason, the induction motor is operated without the rare-earth magnets. The efficient development of induction motor is more important for economical scheme. A torque of the induction motor is computed and the correlation between dimension and resistance of the squirrel cage rotor is investigated. Also, the correlation between leakage reactance and torque was analyzed with respect to the same dimension of rotor with different shapes. Therefore, this paper proposes the method of improvement for squirrel cage rotor.

최근 중국의 희토류 자석 생산 독점과 수출 규제로 인해 희토류 자석의 가격이 급등하였다. 이러한 경제적인 문제로 인해, 희토류 자석을 사용하지 않는 유도전동기의 연구가 활발히 이루어지고 있다. 이 논문에서는 유도전동기의 토크를 계산하고, 농형 유도전동기의 회전자 단면적과 저항에 관한 상관관계를 연구하였다. 또한, 회전자의 단면적이 같고 형상이 다를 경우, 회전자의 누설 리액턴스와 토크의 상관관계에 대해 분석하여 농형 유도전동기를 개선하고자 하였다.
