Bonded NdFeB magnets are made of permanent magnet powder mixed with adhesive materials such as rubber or hard and light plastic, and are directly formed into permanent magnet parts of various shapes according to user requirements, mainly ring-shaped.
The magnetic properties of bonded NdFeB magnets are not as good as those of sintered NdFeB magnets, but they are easy to manufacture multi-stage magnetized ring magnets, have excellent performance consistency and uniformity, and are easy to form integrally with other metal or plastic parts. , which is much higher than the magnetic properties of bonded ferrite, and is widely used in various micro-motor and sensor systems. The specific uses of bonded NdFeB can be divided into:
Digital Products: Hard Disk Drive Magnets (HDD) - This is currently the largest application area for bonded NdFeB.
Office OA products: drive motors for printers, motors for scanners, synchronous feed motors (STP) for copiers, magnetic rollers for laser printers, etc.
Automotive motor and magnetic sensor products: including EPS power steering sensor magnets, wiper motors, window motors, seat adjuster motors, etc.
Other types of industrial and household motors: mainly include various types of servo motors, motors for power tools, air-conditioning refrigeration motors, etc.
