  • Fundamental investigation of an X-YLSM

    Summary form only given. The linear motor has attracted attention in the field of transportation, etc., because it generates linear thrust directly without contact. In general, linear motors generate only 1-dimensional thrust. The authors propose an X-Y linear motor which is composed of an iron core and two separate windings in the horizontal X and Y directions. Exciting one winding gives 1-directional thrust, and exciting another winding gives orthogonal thrust. Total thrust is obtained as a composition of the 2 thrust vectors controlled by each current. This is useful for switching actuators in transportation applications, etc. The authors proposed this application and report its characteristics.

  • 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.

  • Measurement of dynamic magnetostriction under rotating magnetic field

    Rotational dynamic magnetostriction was measured as a function of rotating magnetic flux density on nonoriented and grain-oriented silicon steel sheets under various magnetization conditions. Rotational dynamic magnetostriction was measured by using a special strain gage which provides x- and y-direction output. Rotational magnetostriction is shown to be considerably larger than conventional alternating magnetostriction along the rolling direction because rotational dynamic magnetostriction is generated by the appearance and disappearance of 90 degrees magnetic domain walls under the rotating flux density. The results obtained explain why the cores of rotating machines and three-phase transformers show larger magnetostriction than that predicted by rolling direction measurements of single-strip sheets under alternating flux.<<ETX>>

  • Modelling and design of line reactances. Application to air gap length calculation

    A new method for analysis and design of line reactances utilising two- dimensional planar models is presented in this paper. Inductance and magnetic flux density are calculated, and their results compared with those measured experimentally. The results obtained are good if compared with those measured once the machine has been built. Moreover, the method herein developed is applied to the calculation of air gap lengths in terms of the desired current and inductance. The kind of reactances studied presents air gaps at the ends of the three limbs (joint of limbs and yokes). The main contribution of this paper is the presentation of a method of industrial application, to be easily developed, with a very important reduction in the time of machine calculation (due to the decrease in the number of nodes and elements compared with the three-dimensional model) for the determination of the air gap length in line reactances.

  • Performance analysis of interior permanent magnet synchronous motor for electric vehicle considering magnetic saturation effect

    In this paper, a simulation algorithm for driving performance considering nonlinear parameters of interior permanent magnet synchronous motor (IPMSM) for electric vehicle such as d-axis, q-axis inductances, and core loss is proposed. D-axis and q-axis inductances are changed according to both current magnitude and the angle between q-axis and current axis because of nonlinearity of magnetic flux density in a rotor core. Moreover, core loss characteristic for the calculation of efficiency map is also changed according to these parameters. Therefore, we calculate d-axis and q-axis inductance 3D tables, and core loss 3D table considering nonlinearity of magnetic flux density by using FEM.

  • Visualization of magnetic flux with mixed frequency components using 3n/2 terminal type AC magnetic flux CT probe

    A visualization method of magnetic flux density distribution using CT (computed tomography) technique is presented. In this method, the sensor (CT probe) is composed of only the coil pattern plane, and can visualize two- dimensional distribution of magnetic flux density of vertical component in the plane. If the sensor is composed as a multilayered CT probe, it is also possible to image the magnetic flux density distribution without physical scanning motion. To perform high sensitivity measurement, we propose a new shape of coil pattern with switch mechanism. We perform visualization of one frequency component of magnetic flux density distribution from a mixed frequency magnetic field.

  • Focusing of brillouin electron beams by use of long-period magnetic fields

    This paper presents theoretical and experimental results on the focusing of Brillouin electron beams by use of long-period magnetic fields. This type of focusing was evolved to overcome limitations on continuous and average powers, efficiency, and operating frequency in state-of-the-art microwave tubes employing short-period sinusoidal focusing fields. The theoretical analysis presents the derivation of the optimum field shape for focusing through a single field reversal, and shows that optimum focusing is achieved when the magnetic flux density is peaked immediately before and after the change of polarity. New theoretical results are presented on the use of long-period focusing fields consisting of optimally peaked reversals separated by constant-field regions. The most important of these results is the high degree of stability possessed by such fields and virtual elimination of stop-bands usually produced by periodic systems. The theory presented is in good agreement with numerical solutions obtained by use of a digital computer. Experimental results obtained on long-period magnet assemblies employing three and seven reversals show beam-transmission efficiencies of 98 percent at perveances comparable to those focused by the optimum state-of-the-art short- period magnets.

  • Design of the Rotary Magnetic Position Sensor with the Sinusoidally Magnetized Permanent Magnet

    This paper proposes the rotary magnetic position sensor (RMPS) which has the sinusoidally magnetized permanent magnet (PM) with a small number of poles. To make the sinusoidal magnetic flux density distribution from the PM, the magnetizing fixture is designed. And the magnetization process is analyzed using Preisach model coupled with 2D finite element method (FEM). Also the simulation result of the magnetization is compared with the experiment result
