Arc Segment Ferrite Magnets For Motors
Ceramic magnet material (Ferrite) is one of the most cost effective magnetic materials. It has a fair to good resistance toward corrosion and it can operate in moderate heat. Ceramic (Ferrite) magnets have low energy product and they are usually used in assemblies containing mild steel.
Ceramic magnets are manufactured using powder technology techniques. The primary raw material – ferrite – is made by using iron oxide and strontium carbonate. Ferrite represents more than 75 percent of world magnet consumption (by weight). It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.

Attributes of ferrite Magnets:
• Least expensive material compared to alnico and rare earth magnets
• High intrinsic coercive force
• Available in simple shapes only due to manufacturing process
• Lower service temperature than alnico, greater than rare earth
• Lower energy product than alnico and rare earth magnets
Features
Ferrite magnets, have strong demagnetization resistance. Because it is hard and brittle, they need special mechanical process. Due to low cost, ferrite magnets have broad application fields, ranging from motors, speakers to toys and crafts. It is the most widely used permanent magnet material.
Ferrite magnets are manufactured through powder metallurgy; therefore, the residual magnetism and recoil permeability are low. But because of strong coercive for and demagnetization resistance, ferrite arc magnets are suitable to work in magnetic circuits under dynamic working condition. The main material is oxide, so they are not easy to corrode.
Applications
Ferrite ceramic arc magnets can be used as rotor or stator in different permanent magnet motors such as electric motors, PM motors, AC motors, DC motors, Linear motors, Stepping motors, Brushless motors etc.
