홈페이지논문 초록 (Abstract)
Variable reluctance (VR) resolver is widely used in traion motor as a po sition sensor such as an encoder and a magnetic hall sensor. VR resolver generates demodulated waveforms and then RDC uses the waveforms to dect ect the rotor position. The demodulated waveforms have to be sinusoidal to defect the position of rotor and each same amplitude. However, it is hard that the waveform issinusoidally generated due to uneven magnetic fields. Therefore, FEM analysis of VR resolver have to be performed to obtain minimize error ratio, varying the many parameters on the shape o f VR resolver. This paper deals that a program is automatically made to design a FEM( Finite Elemental Method) model and detect error of a rotor position on t he model of variable reluctance resolver by coupling FEM analysis progra m with Excel Visual Basic. This program can easily design a FEM model of VR resolver by inputting the parameters affecting the demodulated volta ge waveform to Excel, and analyze error ratio of the rotor position on t he model of VR resolver by using an algorithm of RDC code.
