FAQ

 

Do you offer custom magnet designs for specific motor models?
Yes. We can customize arc, ring, or block shapes, magnetization direction, and magnetic grade according to your motor design or technical drawings.

 

How do ferrite magnets compare to NdFeB magnets?
Ferrite magnets are more economical and corrosion-resistant, making them ideal for general-purpose DC motors, while NdFeB magnets provide higher magnetic strength for compact or high-performance designs.

 

Can the magnets operate in high-temperature environments?
Yes. Ferrite magnets have a high Curie temperature (around 450°C) and maintain stable magnetic properties up to about 250°C, depending on the grade.
