전기자 권선 방법에 따른 매입형 영구자석 동기 전동기의 특성 비교

Performance comparison of IPMSMs with distributed and concentrated winding is presented in this paper. Two IPMSMs have been designed and fabricated with identical rotor dimension, air-gap length, series tum number, stator outer radius, and axial length except winding configuration. Basic parameters and machine performance, such as resistances, back emf, output torque, and efficiency, are compared. From the comparison results, motor design considering winding configuration is discussed.
