High Flux Core for EV

High Flux Core for EV

Ferrite a series if iron oxide and other oxide compound (or called ceramic materials), characteristic is low saturation induction (below 0.5T), high permeability, high electrical resistivity, and used in high frequency application. Typical there are Mn-Zn cores, Ni-Zn cores and Mg-Zn cores.

Classification of soft ferromagnetic materials

1. Ferrite a series if iron oxide and other oxide compound (or called ceramic materials), characteristic is low saturation induction (below 0.5T), high permeability, high electrical resistivity, and used in high frequency application. Typical there are Mn-Zn cores, Ni-Zn cores and Mg-Zn cores.

2. Metallic soft ferromagnetic materials – it has higher saturation induction and lower Hc when compared with ferrite material. Mainly has iron series like industrial pure iron, iron powder cores; ironnickel series like MPP cores and High Flux cores, Iron silicon series like sendust core, Fe-SiTM and silicon steel sheet.

3. Amorphous and Nano crystal materials – A newly developed material in late 20th century
