Nonoriented Magnetic Steel with improved texture and permeability
Journal of Materials Engineering and Performance, 1993Co-Authors: H. Huneus, T. Kochmann, K. Günther, V. Plutniok, A. SchoppaAbstract:In nonoriented silicon Steel, high-field permeability usually decreases with decreasing core loss. Recently developed Steel grades offer higher Magnetic polarization and medium-to-low total loss due to improved crystallographic texture.

Medium alloyed Magnetic Steel with low core loss and high permeability
Journal of Magnetism and Magnetic Materials, 1992Co-Authors: H. Huneus, T. Kochmann, A. Schoppa, H. WichAbstract:In non-oriented silicon-Steel the high-field permeability usually decreases with decreasing core loss. A new Magnetic Steel grade Staboperm T 1 is presented which combines the low core loss of high silicon Steel grades with the high Magnetic polarization of non-alloyed grades.

Iron losses in salient-pole synchronous machines considering unidirectional and elliptic magnetization
2009 8th International Symposium on Advanced Electromechanical Motion Systems & Electric Drives Joint Symposium, 2009Co-Authors: G. Traxler-samek, G. ArdleyAbstract:When designing salient-pole synchronous machine, attention must be given to power losses in stator core laminations. In order to reduce these losses to a possible minimum, Magnetic Steel sheets are used.

Lightning Current Observation on UHVAC Transmission Lines by Improved Magnetic Steel Rod Method
2020Co-Authors: Anfeng Jiang, Zhengcai Fu, Zhen XuAbstract:Lightning stroke is the main threaten to the safe operation of UHVAC transmission lines. The Magnetic Steel rod method had been widely used as a traditional method for lightning accident and lightning current investigation in high voltage transmission lines. For the application of the Magnetic Steel rod method on UHVAC transmission lines, this paper proposed a practical and easy improved method of installing the Magnetic Steel rods directly on the transmission towers. The residual magnetism curve and accuracy verification of the proposed method was obtained through complex Steel structure impulse current experiments. The Magnetic Steel rod location on UHVAC transmission tower was analyzed by the numerical analysis software MagNet. The application results of the proposed method on the first demonstration and test UHVAC transmission line is presented. The obtained datasets after one storm season was analyzed through ElectroMagnetic Transients Program. It is shown that the proposed method is feasible. Copyright © 2014 IFSA Publishing, S. L.

Investigation of lightning strokes to UHV transmission lines by improved Magnetic Steel rod method
2012 International Conference on High Voltage Engineering and Application, 2012Co-Authors: Anfeng Jiang, Zhengcai Fu, Junfeng LiAbstract:Lightning strike is still an important threaten to the safety operation of UHV transmission lines. As a traditional method for lightning accident and lightning current investigation, the Magnetic Steel rod method had been widely used in high voltage transmission lines. Lightning rods were often raised up on transmission line towers and then the Magnetic Steel rods were installed around it for the purpose to get an idea environment for the installation of Magnetic Steel rod and relatively accurate measurement of the lightning current. For the application of the Magnetic Steel rod method on UHV transmission lines, this paper proposed a practical and easy method of installing the Magnetic Steel rods directly on the transmission towers' angle Steel structures and fittings, which do not need to install lightning rods on the towers. Preliminary application results of the proposed method on the demonstrating and testing UHV transmission line is presented. The obtained datasets after one storm season was analyzed. It is shown that the proposed method is feasible.

A study of the loss characteristics of the amorphous Magnetic material under nonsinusoidal wave Magnetic flux
Electrical Engineering in Japan, 2020Co-Authors: Shinichiro Hori, Kazurou Harada, Yoshiyuki Ishihara, Toshiyuki TodakaAbstract:This paper presents a study on iron loss characteristics of an amorphous Magnetic material under nonsinusoidal wave Magnetic flux. The iron loss characteristics of the amorphous Magnetic material have been compared to those of grain-oriented Magnetic Steel sheets. Measurements of the iron loss have been carried out by means of an SST. It was found that the ratio of the iron loss increase of the amorphous Magnetic material under the excitation by distorted waveforms and symmetric PWM waveforms is lower than that of grain-oriented Magnetic Steel sheets. On the other hand, the ratio of the iron loss increase of the amorphous Magnetic material under the excitation by asymmetric PWM waveforms is higher than that of grain-oriented Magnetic Steel sheets. © 2004 Wiley Periodicals, Inc.

Structure deformation analysis caused by magnetostriction of Magnetic Steel sheet using combination of ElectroMagnetic and Structure analysis
The XIX International Conference on Electrical Machines - ICEM 2010, 2010Co-Authors: Wataru Kitagawa, Koji Fujiwara, Yoshiyuki IshiharaAbstract:In this paper, combined analysis method of ElectroMagnetic and Structure analysis which describes how the Magnetic Steel sheet deformed by specifying the direction of nodal force against the element, in case the Magnetic flux was distributed on it, was proposed. Deformation by magnetostriction of the Magnetic Steel sheet using structure and electroMagnetic numerical analysis, and analysis of natural frequency and the result of measurement confirmed that the resonance occurred when magnetostriction frequency and natural frequency of the Magnetic Steel sheet were getting close. Also, larger resonance was confirmed when the shape of Magnetic core deformed by magnetostriction and the eigen mode were close.

A Study of the Loss Characteristics of the Amorphous Magnetic Material under the Non-sinusoidal Wave Magnetic Flux
Ieej Transactions on Fundamentals and Materials, 2003Co-Authors: Shinichiro Hori, Kazurou Harada, Yoshiyuki Ishihara, Toshiyuki TodakaAbstract:This paper has investigated iron loss characteristics of amorphous Magnetic materials under the non-sinusoidal wave Magnetic flux. The iron loss characteristics of amorphous Magnetic materials have been compared with grain-oriented Magnetic Steel sheet. The measurement of the iron loss has been carried out with SST. As a result, it is found that the increase ratio of the iron loss of the amorphous Magnetic material under the excitation of distorted waveforms and symmetric PWM-waveforms is less than that of the grain-oriented Magnetic Steel sheet. On the other hand, it is found that the increase ratio of the iron loss of the amorphous Magnetic material under the excitation of asymmetric PWM-waveforms is larger than that of the grain-oriented Magnetic Steel sheet.
