Arc Ferrite Magnet
Description
Ferrite Arc Magnet
Ferrite magnets are fabricated by calcining the mixture of Barium carbonate (BaCO3) or Strontium carbonate (SrCO3) and iron oxide (Fe2O3) to form a metallic oxide. Almost all of ferrite arc magnet is used in motor applications. As the core component of the permanent magnet direct current (DC) motor, ferrite arc magnet is commonly used in the motors of household electrical appliance, automotive, and power tools. Ferrite magnets have excellent temperature stability which can be utilized up to 250 degrees Celsius besides superior corrosion resistance.
