With the accelerating electricity consumption and increasing threat from the green-house effect and consequential environmental degradation, all the industries are stepping forward into the reduction of consumption and loss of energy. Though increasing the energy production will meet the demand but it will lead to increased strain on natural resources and hence the environment. The better way to tackle the problem lies in the reduction of core losses that is related to the generation and transformation of electricity.
All transformation from generator to electric socket and finally computer screen or hair dryer is achieved by a simple device consisting of copper winding around a core of a soft-magnetic material, usually iron or an electric steel, and losses comes from the resistance in the copper and from the magnetization of the core material. Iron based soft magnetic composites are often termed ferromagnetic composite iron (abbreviated as FCI) or soft magnetic composites (abbreviated as SMC), increasingly used for soft magnetic applications. Efforts to improve the performance of electrical devices and to create the new high quality applications lead to the optimization of their design and application of existing magnetic materials such as soft magnetic composites (SMC). These materials are manufactured from iron and iron-based powder particles pressed together with a dielectric binder using the powder metallurgy compaction process. In low frequency applications (up to 50 kHz), high purity coarse iron powder is used with a thermoset resin powder to compete with low carbon steel laminate constructions. These applications will include small motors, reluctance motors and brushless dc motors; which also requires hard magnetic components for an efficient design.
Advancements in materials research has put the imagination into reality to produce high quality material with soft magnetic properties. SMC compete with steel laminations at a similar production cost or even cheaper. The benefits of replacing the conventional laminated core in an electric machine with the SMC are considerable, and include reduced high frequency tooth ripple losses since the SMC has essentially no eddy current losses, modular construction allows the possibility of easy removal of an individual modular unit for quick repair or replacement, stator is easily recyclable, reduced bearing currents. Soft ferrite has the dominant share amongst the soft magnetic composites. Use of SMC in automotive application will also expand, for instance in electro-mechanical valve opening and closing, direct fuel injection, noise suppression etc. Iron based soft magnetic composites are considered to have major potential in electric motors. Due to the significant economic and environmental benefits, SMC materials possess great potential for application in electrical machines, particularly those with complex structures. However, because of the outstanding drawbacks of the SMC, as lower magnetic permeability and lower saturation flux density compared with laminated steels, particular efforts to overcome them should be done.
