PRODUCT QUESTIONS
Before You Send a Drawing.
Why is ferrite often larger than NdFeB?
Ferrite has a lower maximum energy product, so the magnetic circuit may need more volume to reach the same air-gap performance. The final trade-off depends on geometry and system design.
Does ferrite need a coating?
Ferrite is a ceramic material and is generally corrosion resistant without a metallic coating. The housing, adhesive and exposed surface still need to be reviewed for the actual environment.
Is ferrite suitable for motor arcs?
Yes. Ferrite arcs are widely used in cost-sensitive motor designs when the available volume and required torque or speed are compatible with the material's magnetic performance.
