Soft magnetic composite (SMC) material is a new soft magnetic material, now it is popular in the designing of permanent magnet machine where high operation frequency and 3-D flux path required, due to its advantages of low eddy current loss and magnetic isotropy.
The switched reluctance motor (SRM) has recently received much attention because of its preferred features in simple and rugged configuration and elimination of permanent magnet (PM).
Silicon steels are widely applied in the magnetic cores design, such as power transformer, electrical machine, and magnet. Magnetic properties of the silicon steel are key factors in design and performance optimization of the electrical apparatus. In the past several decades, one and two dimensional (2-D) magnetic properties testing methods have been developed for single sheet silicon steel specimen...
Embedded Mask Patterning (EMP) method uses a plasma etching process to form ultra-small but thermally stable isolated L10-FePt magnetic grains with embedded Ru hardmask1,2. It has been demonstrated as a promising and highly cost effective solution to fabricate the ultra-high density magnetic media for the next generation hard-disk drive technology, such as heat-assisted magnetic recording (HAMR)....
By using the powder metallurgy technology and magnetic isotropy characteristic of the soft magnetic composite (SMC) material, various kinds of the complex structure permanent magnet synchronous machines (PMSMs) can be designed and fabricated easily e.g., axial-flux machine, claw pole machine (CPM) and transverse-flux machine (TFM) [1]-[4]. With the global coil applied in the CPM and TFM, the CPM and...
