Impedance Characteristics Analysis of Magnetic Type Angle Sensor in High Frequency Region

Abstract

The impedance characteristics of the magnetic type angle sensor are analyzed by using the finite element method. The impedance characteristics were accurately calculated by taking into account high frequency characteristics of the cores and the end coils. The magnetic permeability of cores is estimated from the calculated results of impedance in high frequency region. The validity of the magnetic permeability in the analysis is confirmed by experiments.
