  • Number of detecting probe and spectral components in two-dimensional magnetic field visualization based on the projection method

    The visualization of precise 2-D or 3-D magnetic flux distribution has been achieved for studying the precise design of magnetic machinery and device. Projection method is one of the useful techniques for measurement and visualization magnetic flux density. To determine the minimum number of probe, spatial frequency component has been discussed. In this probe design, it is important to choose the number of probe coil because this parameter will affect the reconstruction accuracy. In order to discuss this probe design, a magnetic flux leakage from the magnetic machinery and device is assumed, and the probe size is used in 100 mm square. Then a calculation model is employed to simulate the reconstruction process of magnetic flux distribution for the purpose of designing the optimum structure of probe.

  • Effects of a remanent magnetization on the sensing signals in magnetic flux leakage type NDT

    Sensitive detection of the defect signals in NDT system is critical. Because of a strong magnetic field in magnetic flux type NDT system, the object itself is magnetized and shows a hysteresis characteristics during the sensing, which might cause a distortion of the defect signals. In this research, the magnetization characteristics of a pipeline in the magnetic flux leakage type non-destructive testing are analyzed. Effects of a magnetic hysteresis of a pipeline are analyzed by Preisach modeling and a magnetic flux density due to a remanent magnetization of gas pipeline is computed and verified by real measurement.

  • An improvement of power indexes of the electrical machine generators based on the magnetic field analyses

    A study of the magnetic flux leakage in the stator tooth-pitch was made using the ELCUT software. This software enables one to observe the places of local saturation and correct the slot dimensions in order to reduce the slot leakage inductance, which generally is a function of the slot shape. After the pitch area optimization, the slot leakage inductance was decreased by 16.4%, thus reducing the total core weight and volume by 1.7%.

  • Justification of an alternative system for one- and two-dimensional magnetic measurements

    A novel two-dimensional measurement set-up for magnetic sheet characterization has been designed and constructed. Experimental verification shows that the inhomogeneity of the magnetic flux through the sample was smaller than the measurement error, whereas the required electric excitation decreased considerably. The aim of this paper is to prove that the new measurement system is superior to the Epstein frame and the rotational single sheet tester (RSST) and can be recommended.

  • Field leakage study and possible ways of improving compression generator parameters

    Summary form only given. This paper deals with a traditional design of a compression generator suggested by V. Kuchinsky and B. Larionov of Efremov Institute of Electrophysical Apparatus (Saint Petersburg, Russia) in the invention registered in Russia in 1980, but with some addition in design for improving of operating characteristics. The author proposes to insert additional conductors (active or passive) in the slots of windings to reduce the magnetic flux leakage in the slot area. The improvement of generator parameters may be achieved due to concentration of magnetic flux to be compressed in the more thin area of air gap between rotor and stator, with corresponding reduction of minimal inductance of generator and increase of energy amplification, which is likely to increase the flux compression stage at the linear magneto-cumulative generators. Numerical simulation of the field in the slot area has been undertaken to study the effectiveness of proposed way of parameters improvement. Two contradictory points of view may be found in this topic. According to the first one, it is effective enough to dispose the electromagnetic shields (active or passive ones) along the sides of slot to reduce the flux leakage at the slot area and to displace the resulting magnetic flux to the gap. Using passive shields appears to be a simpler resolution of the problem. According to the second point of view, it would be better to increase the quality of electric circuit of the generator due to enhancement of main winding cross-section instead of mounted shields. The numerical simulation has been performed to define which points of view are closer to the truth. The pictures of the magnetic flux distribution were obtained using the finite-elements simulating program created by Dr. Igor Petuhov at the Institute of Electrodynamics. The effectiveness of electromagnetic shielding of the flux leakage in the slot area has been proved.

  • Examination of how to detect two cracks by alternating flux leakage testing

    Summary form only given. The alternating magnetic flux leakage testing is used for the detection of cracks in steel plate. How to detect and distinguish two cracks, which are located at very short distance is one of important issues of this testing. In this paper, a technique of how to detect two cracks which are located at very short distance (for example, 0.5mm) is investigated using the perpendicular (Bz) and parallel (Bx) components of the leakage flux density calculated by 3-D edge-based hexahedral FEM.
