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