Injection Molded Bonded Ferrite Magnet Rotor Assembly
Injection molded bonded ferrite magnets have gained popularity thanks to its lower cost, flexibility in magnetization and easy assembly process.
Injection molded ferrite magnet rotor assembly
Conventional magnetic rotors are composed of a shaft and individual magnets arranged in N-S-N-S configuration. The magnets come in either arc segment or rectangular shapes. The magnets are mostly surface-mounted using adhesive. An injection molded bonded ferrite magnet, which often come in ring shape, are directly overmolded on the shaft. The ring magnet is multipole-magneitized in the mold. This process greatly increased the assembly efficiency.
