Hard Ferrite Ceramic Arc Magnets

Ferrite(Ceramic) Magnet is manufactured from oxide materials using powder metallurgical process. Ceramic magnet is most widely used because of its low cost, high-energy, good electric insulation and excellent resistance to demagnetization. The most common type of ceramic magnets are anisotropic strontium, anisotropic barium and isotropic barium magnet.

Hard Ferrite Ceramic Arc Magnets

Ferrite arc magnets or Ceramic arc magnets are made by mould pressing and grinding. They do not need coating for using. Because the cheap raw material cost, This Ceramic magnets are widely used in DC motor or start motor of Auto, Motorcycle, Electric tools, Gym equipment, Home electrical appliance, etc.

Y30BH Segment Ferrite Magnet

The influence of magnetic segments performnance on motor

A.High residual magnetic induction intensity Br. Due to under the same magnetic pole surface area and air gap,

high Br can produce large output torque and large power.

B.Hi Hcb. Due to high Hcb to ensure the required EMF of motor output

C.Hi Hcj. High Hcj can ensure that the motor has strong anti-overload demagnetization, anti-aging and anti-low temperature ability.

D.Hi (BH)max. The higher (BH) max, the better actual operation coefficient of the permanent magnet ferrite in the motor.

E. The bigger flux the better,which will greatly improve the working efficiency of the motor.

F.The better rectangle degree of demagnetization curve, the smaller the dynamic loss of the motor.

G.The higher resistivity of the ferrite, the smaller the eddy current loss.

H.T he temperature coefficient of permanent ferrite is small so can got a good temperature stability at high temperature

I.The starting current is small and the time constant is small. The impact on the power supply is small.

Ferrite magnets features

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 Arc Magnets has good anti-corrosion performance, no surface treatment needed. At present, we have put our emphasis on the application for electric motors, magnetic separators, magnetic resonance imaging and automotive sensors.

Main products includes: hard ferrite arc or segment, ring magnets, rectangular magnets etc. 

Ferrite magnets have the following advatages: high coercive force, high electric resistance, long-time stability, and economical price. Meanwhile, we can manufacture new tools according to customers`demand.
