Product Description:

NdFeB Halbach magnet is a special magnetic component consisting of NdFeB permanent magnets that can provide controlled high magnetic field strength without the use of magnetically permeable materials. Halbach magnets,  with the smallest magnet through a certain direction of magnetization to produce the strongest magnetic field to reduce the cost of materials.

The most obvious benefit of a Halbach Array is that the field produced is very strong when compared to other arrays having the same amount of the magnet alloy. The arrangement essentially increases the efficiency of the magnetic circuit. A Halbach array is an arrangement of permanent magnets that causes an one-sided flux, i.e. the magnetic field is maximized on one side, while minimized on the other.

Application:

Halbach Magnet's main function is holding, fixturing, linear coupling application, so it is mainly used for motor, generator, magnetic resonance, magnetic levitation high-speed rail,pre-polarization, chemical single crystal growth. For example, the traditional permanent magnet motor often use distributed winding to weaken the influence of harmonic magneto motive force. In the Halbach motor because of its high magnetic field sine distribution, harmonic magnetic field less affected, it can be used centralized winding. With Halbach motor magnet arrangement, can reduce the torque ripple of the motor, so the bearing requirements for the motor greatly reduced.

In addition, the magnetic levitation super high-speed rail is the principle of passive rejection, its periphery is surrounded by a series of magnets. These magnets are arranged in the Halbach array so that the train has an outward magnetic force, not to the passenger's end. Each cabin is suspended in the air, not contact with the ground, that makes running up without friction. It is because there is no friction and close to the vacuum, it makes the train can achieve very fast speed.
