Motor, transformer and actuator core usually by groups of magnetic slice of implementation.
Nowadays, due to the development of powder metallurgy, have introduced the possibility of using magnetic powder instead of lamination.
In general, the material called soft magnetic composite material or SMC.
Soft magnetic alloy is made of cover is predestined friends the layer of iron-based powder;
Giving up the fold type magnetic circuit and adopt magnetic powder can acquire the basic advantage is can change the design method of magnetic flux from 2 d to 3 d design figure 6: material is isotropic, and can load flux on the direction in the same nature.
In many cases, using by molding pieces could be an interesting solution, is if you are using a magnetic board achieve the desired geometry complexity, it is the same.
These elements can greatly simplify the production process.
In this article, using a novel SMC materials instead of I.
我。
P。
C。
Proposed to ordinary iron powder mixed with organic resin is used, to provide available in the market, it is important to note that in order to I.
我:P。
C for reference is actually used in the application materials;
This proved that will be described in this article the SMC compared with an alternative choice.
In previous activities, the author has experienced the experience of resin is used to realize the bonded magnet, is proposed to use the same resin SMC.
