Hard and soft magnetic composites with modified magnetic properties
World Journal of Engineering, 2011The paper deals with methods of tailoring magnetic properties of soft and hard magnetic composites. Comparison of magnetic properties of injection moulding and compression moulding Nd-Fe-B magnets are presented. Magnetic properties of Nd-Fe-B bonded magnets were tailored by different ways such as: amount of resin, addition of barium ferrite, Al or Fe ...

Magnetization behavior of hard/soft-magnetic composite pillar
Journal of Magnetism and Magnetic Materials, 2008Abstract Hard/soft-magnetic composite pillar array medium is proposed for ultra-high-density recording media. Magnetization reversal process for a single hard/soft-magnetic composite pillar in the medium is calculated using the Landau–Lifshitz–Gilbert equation.

Application of soft magnetic composites in active magnetic bearings
IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011One of the main application areas of active magnetic bearings is turbo machinery. Such machines run at high speeds and through application of magnetic bearing bearings mechanical contact and friction between rotor and stator can be avoided. Nevertheless magnetic bearings still cause rotor losses through eddy currents and magnetic hysteresis effects ...

3D Magnetic Reluctivity Tensor of Soft Magnetic Composite Material
2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006Soft magnetic composite (SMC) materials are particularly suitable for construction of electrical machines with complex structure and 3D magnetic flux. For design and analysis of such 3D flux machines, 3D magnetic properties of the magnetic materials should be properly determined, modeled and applied for calculating the magnetic field distribution ...

The Influence of the Kind of Soft Magnetic Powder on Power Losses in Soft Magnetic Composites
2010Soft magnetic composites called dielectromagnetics find more and more applications in electric transducers. Power losses are among the main parameters of soft magnetic materials, decisive for their application. The kind of magnetic powder and technology of production of magnetic elements influences the level of power losses.

Influence of cryogenic temperature on magnetic properties of soft magnetic composites
Powder Metallurgy, 2014Magnetic properties of Fe based composite materials with different particle sizes under a cryogenic condition have been investigated. Realisation of this venture has been carried out at the liquid nitrogen temperature. Results of energy loss density were obtained from measurements of the static (dc) hysteresis cycles ranging from 0·1 to 1·0 T. In turn,

Three-dimensional magnetic properties of soft magnetic composite materials
Journal of Magnetism and Magnetic Materials, 2007A three-dimensional (3-D) magnetic property measurement system, which can control the three components of the magnetic flux density B vector and measure the magnetic field strength H vector in a cubic sample of soft magnetic material, has been developed and calibrated.
