All kinds of miniature motors adopt bonded magnets, which have simpler production process, higher reliability, lower cost and higher efficiency, and have partially replaced sintered magnets and ferrite magnets.
Hard disk motor (including drive and fan), due to its high dimensional accuracy, strict dynamic balance requirements for high-speed rotation of components, high cleanliness environment, low cost and miniaturization requirements, is now completely produced with bonded magnets.
Bonded magnets have the advantages of small size, light weight and stable magnetic properties. They have been widely used in motor actuators for moving, opening, lifting and other automotive components, automotive pumps and various sensor motors.
