Introduction and Application
The eddy current loss of SMC iron core is smaller than stacked silicon steel core under high frequency alternating magnetic field. SMC iron core is a new material with 3D magnetic conductivity with high magnetic properties. With powder metallurgy (PM) process, the product has high dimensional accuracy, good temperature stability and low electromagnetic noise which is cause by the low hysteresis expansion coefficient. At present, it has been widely used by parts manufacturers. Its shape-changable design is used to meet the requirements of motor miniaturization. Its compact, portable and low-cost solutions will become the future development trend.
