Radial multi-poles bonded ring magnets for motors
In terms of magnetic property, Bonded NdFeB magnet is much better than the dry-pressed anisotropic ceramic magnet and injection ferrite magnets. While desgining the motors, it need to be in line with the motor performance requirements: high and low speed torque size, low price, small size to choose.
Different types of magnetic materials for magnetic values are as bellows:
