Motor segment magnet

Specifications

Motor segment magnet

There are mainly two types of ferrite magnets, Barium ferrite (BaO.6Fe2O3) and Strontium ferrite (SrO.6Fe2O3). Compared with other permanent magnets, sintered ferrite magnet is cheap. It is most suitable for most sensitive, but need not very high performance applicaitons. As this is a non-metal magnets, it is the ideal magnets for applications that require non-rusty magnets in humit envirument. Sintered ferrite magnets are widely used in many different applications, such as motors, cars, magnetic selection loudspeakers, and many special applications.  Ferrite magnet block 

Isotropic ferrite magnet

Properties:

Sintered ferrite (ceramic) magnets are also available in forms of isotropic and an-isotropic. The magnetic properties of isotropic ferrite are the same in all directions, therefore they can be magnetized in any pole arrangements. An-isotropic ferrite magnets, on the other hand, can only be magnetized in the direction they are oriented during production, but they have much higher magnetic strength than isptropic ones.  Ferrite magnet block

Characteristics

Sintered ferrite magnets can be used in between -40 °C and +200 °C
Being hard and brittle, they can be cut by using diamond tools.
The raw material of sintered ferrite magnets is oxide, thus they would not be rusted under severe environment nor affected by many chemicals (except some strong acids).
