조립 후 착자 공정을 고려한 컴프레서용 자속집중형 모터 특성 비교

다국어 초록 (Multilingual Abstract)

The number of devices using motors is increasing worldwide, and interest in permanent magnets, which are essential components of permanent magnet type synchronous motors with advantages of wide operating range and high power density, is increasing. In particular, rare-earth permanent magnets with high residual induction are used in various fields such as automobile driving motors , for example, EPS motors. However, due to the limited area in which rare earth elements exist, various problems such as supply-demand imbalance and price surges may occur. In response to this, various types of motors that do not use rare earth elements have been developed. In this paper, the characteristics of various types considering the magnetization process after assembly of the concentrated flux synchronous motor are reviewed, and through this, the design direction of the motor is suggested.
