Ferrite Arc Magnet

Ferrite magnets encounter difficulties in attaining precise shapes and dimensions during the pressing process under an external magnetic field, hindering direct production to meet application needs. Consequently, additional machining of sintered blanks is essential to ensure ferrite arc magnets align with required specifications for practical use.

Due to their hard, brittle, and electrically insulating properties, ferrite magnets can only be machined via grinding and slicing to achieve dimensional accuracy, geometric tolerance, and surface smoothness. Thus, machining a ferrite arc magnet primarily involves profile (contour) grinding, as a ferrite arc magnet cannot be processed using wire-cutting methods.

In contrast to Neodymium arc magnets used in both radial and axial flux systems, ferrite arc magnets are mainly utilized in radial flux motors. These magnets typically have a uniform arc shape or specialized profiles crafted to enhance magnetic performance.

Ferrite arc magnets feature diametrical magnetization, perpendicular to the rotation axis, and are often magnetized this way, used in pairs to create the desired magnetic flux distribution. Unlike Neodymium arc magnets, pure radially magnetized ferrite arc magnets are available for specific applications.
