Bonded NdFeB magnets are used in a wide range of micro motors and sensor systems due to their ease of manufacture of multi-pole ring magnets, their excellent consistency and uniformity of performance, their ease of integration into other metal or plastic components and their much higher magnetic properties than bonded ferrite magnet.
4-pole neodymium magnetic ring 12x10x1.7mm physical sample;
Specific applications for bonded neodymium magnet can be classified as:
Digital products: hard disk drive magnets (HDD) - the largest application area for bonded Neodymium today
Office OA products: drive motors for printers, motors for scanners, synchronous feed motors (STP) for copiers, magnetic rollers for laser printers, etc.
Automotive motors and magnetic sensors: EPS power steering sensor magnets, wiper motors, window crank motors, seat adjuster motors, etc.
Other industrial and household motors: mainly servo motors, motors for power tools, air conditioning and refrigeration motors, etc.
Guess you are curious;
