Ferrite (ceramic) magnets are essentially composed of oxide materials with barium carbonate or strontium carbonate, manufactured under a powder metallurgical process
High saturation induction of 1.56 Tesla—Reducing component volume
Low coercivity—Increasing component efficiency
Low core loss—Reducing temperature rise in devices
Variable permeability by different heat treatments—Satisfying various application requirements
Excellent thermal stability—Having a highest service temperature of 130oC
The feature of low recoil permeability, along with the high coercive force, makes them highly resistant to demagnetizing fields. In addition, their relatively low specific density and economical cost are also very attractive to the magnet designers. When designing the ferrite magnets for a particular application, primary consideration should be given to its shape limitation due to the powder metallurgical manufacturing process and the temperature dependence of ferrite materials
Ferrite magnets have good anti-corrosion performance, no surface treatment needed. There are two manufacturing process for ferrite magnets: dry process and wet process. By dry process, can produce isotropic & anisotropic magnets; by wet process, only anisotropic magnets can be produced. Isotropic ferrite magnets are not oriented and can be magnetized in any direction; anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation. For dry process, the tool can be changed and developed easily, while for wet process, it is complicated to change the tool and the tooling charge is much higher. At present, we have put our emphasis on arc segment magnets for electric motors, disc magnets and block magnets for special applications
We specialize in ODM and OEM various magnet rotors for motors. Magnetic rotors which are made by plastic injection outside NdFeB magnets or ferrite's in can, high in efficiency and working with low noise. They are widely applied in cars, water pumps, disk drivers, starting motors of motor bikes and stepping motors.
