  • microstructure and Magnetic properties of soft Magnetic Powder cores of amorphous and nanocrystalline alloys
    Journal of Magnetism and Magnetic Materials, 2013
    Co-Authors: Yide Yi, Wei Shao, Yanfang Shao
    Abstract:

    Abstract With the development of modern ferroMagnetic technology, soft Magnetic Powder cores (MPCs) of amorphous and nanocrystalline alloys have been intensively studied for their excellent soft Magnetic properties such as high flux density, low coercivity and reduced core loss due to amorphous state and nanocrystalline grains of 10–20 nm dispersed in a residual amorphous matrix. In this paper, the microstructures and soft Magnetic properties, i.e., maximum Magnetic induction B m , effective permeability μ e , DC-bias properties and volume power losses P CV of MPCs made from amorphous Powder of gas atomization and nanocrystalline Powder of pulverized melt-spun ribbon were investigated and also compared on the basis of the same level of μ e . It is found that μ e of both kinds of MPC keeps unchanged up to 1 MHz. The amorphous MPC has lower P CV at lower frequency range, while the nanocrystalline MPC has lower P CV at high frequency range instead. Also, the nanocrystalline MPC has better DC-bias property. Moreover, the DC Magnetic properties and the changes of P CV of both MPCs with frequency and flux density are also studied. Furthermore, the electroMagnetic characteristics, the microstructures and the mechanisms accounting for these phenomena of both MPCs are also discussed.

  • Effect of Process Parameters on the Properties of FeSiAl Magnetic Powder Core
    Journal of Magnetic Materials and Devices, 2008
    Co-Authors: Sun Ke-wei
    Abstract:

    FeSiAl Magnetic Powder core was prepared from ball milling podwer followed by molding. The effect of process parameters on the quality factor and effective permeability of FeSiAl Magnetic Powder core has been studied in terms of Powder sizes, mount of insulation binder, cooling conditions and temperatures of heat treatment. It was found that, with decreasing the size of FeSiAl Magnetic Powder, the effective permeability of the sample decreases but the quality factor increases. The more insulation binder results in a higher Q value and a lower μe. The heat treatment could improve the effective permeability as a result of reduction of internal stress. Low cooling rate is more helpful than high cooling rate for improving effective permeability.

  • Magnetic Powder forming simulation subjected to pressing in Magnetic field
    Journal of Materials Processing Technology, 1994
    Co-Authors: Shigeyuki Tamura, Tatsuhiko Aizawa, Junji Kihara
    Abstract:

    Abstract Magnetic field forming is a promising method to produce high quality ferroMagnetic materials. In this process, Magnetic Powder is formed in the high Magnetic flux by the metal injection molding process. However the parameter of this process is very complicated and it is still difficult to obtain the optimum forming conditions. The analytical method is very effective tool to make such optimum forming design and to investigate the mechanism of the Magnetic Powder flow under applied Magnetic field and pressing. We developed the coupling method of pressing load with Magnetic field to simulate the Magnetic field forming. In this method, granular modeling is utilized to simulate the mechanical behavior of the Powder particles and the Magnetic field is considered as a body force. In the numerical example, we analyzed the difference of the Magnetic Powder flow for pressing schedule and the preferred orientation of magnetizing of the Magnetic Powder is taken into account in the particle modeling.

  • Magnetic-Powder Clutch Current Control based on Neuron PID
    IEEE Transactions on Power Electronics, 2008
    Co-Authors: Zhang Xun
    Abstract:

    The Magnetic-Powder clutch is widely used in mini-buses,because its transferred torque is linear to its field current and the electronic control strategy is easily implemented.According to AMT with Magnetic-Powder clutch,the drive and control circuits are designed.Because there are some non-linearity in the drive part,and some interference caused by the environment while vehicle running,it's difficult for traditional PID control to work best,then neuron which has ability of self-study and self-adaptation is applied to construct a self-adaptation controller.And then some experiments are carried out to test the control strategy.The results shows that,the controller has nice dynamic performance,and the system has nice self-adaptation.
