가변 릴럭턴스 레졸버의 해석과 위치 신호의 비선형성 시뮬레이션 연구

Variable reluctance(VR) resolver is widely used as a position sensor in an application of electric vehicle. VR resolver detects absolute angle of rotor position of electric motor. In the paper, analysis method of VR resolver including resolver-to-digital converter (RDC) is proposed by using finite element method (FEM). It is possible to analyze position errors from RDC and VR resolver by proposed method.
