PROBLEM TO BE SOLVED: To provide a method and an apparatus for well-linearly detecting a magnetic flux and a current regardless of a characteristic of a magnetic flux detection element although the detected magnetic flux is relatively large.坪井 浄...
The singularities of an irrotational magnetic field are lines of electric current. This property derives from the relationship between vector fields and the topology of the underlying three-space and allows for a definition of {cosmic field} flux tubes and flux ropes as extit{cores} (in the sen...
We study current practices and motivate the need for improvements. To facilitate the analysis, we develop an analytical model to represent the 3-dimensional magnetic flux leakage field due to a surface-breaking defect in the specimen. The model is derived from first principles using the concept ...
Magneto-optical imaging (MOI) is an excellent tool to visualize magnetic flux patterns in superconductors with high spatial as well as temporal resolution. Furthermore, full quantitative MOI allows the determination of main properties of the (metastable) critical state, such as Meissner and critical ...
These methods rely on the machine's inherent flux/current magnetic characteristics to infer rotor position from measurements of stator flux-linkage and current during normal phase excitation. Position estimation schemes are presented for SRMs in which both single and multiple simultaneous phases are ...
A system and method for current sensing includes a conductor configured to receive current flow therethrough and generate magnetic flux thereabout. The current sensor system also includes an anti-differential current sensor configured to monitor magnetic flux about the conductor. The anti-differential cur...
One single-layer and two four-layer example winding structures are used to illustrate the impact of excitation frequency on the magnetic field intensity and current density distributions in transformer windings. By plotting the distributions as phasors in three-dimensional isometric plots, greater insight...
We developed a combined technique using magnetic flux penetration and an eddy current test (ECT). The magnetic measuring system consists of a pair of magnetic probes having an induction coil and detection coil, a lock-in amplifier, a current source, and a personal computer. The magnetic flux ...
