HEV용 매입형 영구자석 동기전동기의 회전자 극수에 따른 운전영역 및 특성 파라미터 분석

Study on the Operation Region and Characteristic parameters in Magnetic Pole of IPMSM for HEV

Interior Permanent Magnet Synchronous Motor(IPMSM) produces two kind of torque that Magnetic and Reluctance torque. The permanent magnet linkage flux Ψa and d-axis and q-axis inductance have an important influence on the torque characteristic of IPMSM. Thus their accurate prediction is essential for predicting performance aspect such as the torque and flux-weakening capabilities. In this paper, we compared the characteristic parameters and operation region of two type IPMSM which has different pole numbers.
