Product Feature
Bonded NdFeB magnet features:
1. Magnetic property between sintered NdFeB magnet and ferrite magnet, it is a high performance isotropic permanent magnet with good consistency and stability.
2. Can be made into permanent magnets of small sizes, complex shapes and high geometric accuracy with press moulding and injection moulding. Easy to achieve large-scale automated production.
3. Can be magnetized via any direction. Multi poles or even countless poles can be realized in bonded NdFeB.
4. Bonded NdFeB magnets are widely used in all kinds of micro motors, such as spindle motor, synchronous motor, stepper motor, DC motor, brushless motor, etc.
