  • study of a new split type magnetizing coil and pulsed field magnetization of gd ba cu o high temperature superconducting bulk for rotating machinery application
    Superconductor Science and Technology, 2006
    Co-Authors: E Morita, H Matsuzaki, Y Kimura, H Ogata, Mitsuru Izumi, Masato Murakami, H Sugimoto, M Miki
    Abstract:

    A new type of magnetization coil was designed to increase the Maximum trapped magnetic Flux Density and the total Flux associated with an appropriate trapped magnetic Flux Density distribution in a high-temperature superconducting bulk magnet. The coil is composed of an inner vortex-type coil wound with an outer solenoid coil. A pulsed current is applied to the inner or the outer coils. Successive applications of pulsed current from both the inner and the outer coils to only the inner coil provide a distribution of trapped magnetic Flux Density closer to being conical in addition to an increase of the Maximum Flux Density and total integrated Flux. The present magnetization technique, the controlled magnetic Flux Density distribution coil method, is useful for magnetized high-temperature superconducting bulk applications such as in rotating machines, generators and magnetic separation.

  • Local Vector Magnetic Characteristic Analysis of a Three-Phase Three-Leg Transformer Model Core
    Materials Science Forum, 2014
    Co-Authors: Kyohei Miyamoto, Takashi Todaka, Masato Enokizono
    Abstract:

    This paper presents results of magnetic characteristic analysis of a three-phase three-leg transformer model core. In the analysis, the finite element method considering vector magnetic properties expressed by the integration-type E&S modelling is used. In this research, in order to reduce total iron loss, local vector magnetic properties for some different T-jointed models are compared in detail. Distributions of Maximum Flux Density, Maximum field strength, axis ratio and iron loss depending on the T-jointed position are clarified.

  • Measurement of vector magnetic properties of Fe-Si-B amorphous material
    IEEE Transactions on Magnetics, 2011
    Co-Authors: Shohei Ueno, Takashi Todaka, Masato Enokizono
    Abstract:

    This paper presents measured 2-D vector magnetic properties of a Fe–Si–B amorphous sheet. The relationship between the magnetic Flux Density and field strength vector under alternating and rotating Flux conditions is clarified by using the 2-D vector magnetic property measurement system. The magnetic anisotropy in plane was observed and it was changed depending on the Flux Density level. Moreover the iron loss depending on the Maximum Flux Density is shown.

  • Flux distributions in three-phase induction motor with disconnection problem
    IEEE Transactions on Magnetics, 1993
    Co-Authors: Masato Enokizono, Takashi Todaka, I. Serikawa
    Abstract:

    The characteristics of a three-phase induction motor with a disconnection problem are measured by using a practical 0.5-kW three-phase, four-pole model in which the stator connection can be selected arbitrarily. The change of the load characteristics and of the Flux distribution for differences in the stator connection is clarified quantitatively to obtain the necessary information in the diagnosis of the disconnection problem. Under the normal condition of three kinds of star connection, the distortion factors of the Flux waveforms are under 2.5%. In the case of disconnection, these values are increased in almost all search coils. When the connection is series-circuit construction, the malfunctioning point can be related to the change of the Maximum Flux Density of the distortion factor.
