Magnetomechanical Damping and Domain Structures in Grain Oriented Silicon Steel Sheets

Residual Stress Distribution in Grain-oriented Silicon Steel

We investigated the residual stress distribution in a grain of laser-irradiated and gearrolled grain-oriented Fe-3%Si silicon steels by X-ray stress measurement method in order to clarify the effect of residual stresses on magnetic domain refining. Dotted cavity lines were formed by Nd:YAG laser with a power density of 3.3 mJ/pulse for the laserirradiated sample. By using a newly developed X-ra...

Comparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester

 Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...

Temperature Effects on the Magnetic Properties of Silicon-Steel Sheets Using Standardized Toroidal Frame

This study designed a detachable and standardized toroidal test frame to measure the electromagnetic characteristic of toroidal laminated silicon steel specimens. The purpose of the design was to provide the measurements with standardized and controlled environment. The device also can withstand high temperatures (25-300°C) for short time period to allow high temperature tests. The accompanying...

Kinetics of Secondary Recrystallization in Grain-oriented Silicon Steel Studied by High-temperature Background

Secondary recrystallization id grain-oriented silicon steel is studied by the high-temperature background damping. Abnormal grain growth involves an abrupt drop of the background. The temperatures of initiation and completion of the secondary recrystallization are, thus, determined for the sane sample from the definite change in background with increasing temperature. The background measured on...
