“Vector (2D) Hysteresis Analyzer System”

Two-dimensional magnetism characteristic measurement is equipped measuring alternating current magnetization characteristic of magnetic material (electromagnetic steel plates, Permalloy) with vector. The vector measurement equipment can measure magnetic characteristic of magnetic material from overall into more details compared with traditional scalar magnetic measurement. We aim at providing solutions for new technique of optimum design such as transformer or electric motor with this equipment. Previously, the scalar finite-element magnetic field analysis method has been used for magnetic field analysis of materials used for transformers or electric motors. Recently, an ecological requirements of these devices being designed with the materials which shows strong magnetic anisotropy such as hi-oriented silicon steel reveals the differences between scalar analytically measured results and actually operated results. In such situation, the vector finite-element magnetic field analysis method has been paid attention. Herewith, we introduce the V-H(Vector-Hysteresis) analyzer which purposed faster and easier measurement of a grained directional steel sheet at various magnetic excitation conditions with vector magnetic characteristics. Measured data would be applied to the E&S Vector two-dimensional measuring method and modeling. This report describes the V-H analyzer and it’s measurement examples.
