Neodymium Tile Magnet

Neodymium tile magnet, also known as curved magnet, Segment shape, tile or arc shaped Neodymium magnet.is a unique shape of sintered Neodymium magnet, then almost all of Neodymium tile magnet is used for both rotor and stator in permanent magnet (PM) motors, generators, or magnetic coupling devices.

Machining Process

Due to technical limitations in the magnetic field orientation molding process, Neodymium tile magnet is always machined from blank. Machining process of curved magnet is normally selected from wire-cutting or copy grinding. Wire-cutting is well adapted to the machining of special shaped magnet, but it also accused of low production efficiency and high processing cost. On the contrary, copy grinding has the competitive advantage in efficiency and cost but short in dimensional applicability. Magnet manufacturers should utilize appropriate machining technology in accordance to the shape, dimension, material utilization ratio, production efficiency, and processing cost.

Magnetization Direction

Neodymium tile magnet&arc magnet for frequently-used radial flux motor is magnetized through diametrical direction and definitely used in pairs. It should be noted that pure radially magnetized Neodymium tile magnets&arc magnets are extremely difficult to manufacture. Fan-shaped tile magnet is commonly served as axial flux motor magnet. For some axial flux motor, a certain quantity of chord magnetized magnet should be placed between regular axially magnetized magnet to form a Halbach array, then obtain more ideal magnetic field strength and distribution.

Application

NdFeB (neodymium-iron-boron) magnetic tiles have a wide range of applications due to their excellent magnetic properties, which include high coercivity, high remanence, and high energy product. Here are some common applications of NdFeB magnetic tiles:

lElectric motors: Electric motors to generate the magnetic fields that drive the rotor. These motors are used in a variety of applications, including automotive, aerospace, and industrial machinery.

 lMagnetic separators: Magnetic separators to separate ferrous metals from non-ferrous materials. They are used in recycling plants to separate metal from waste streams and in mineral processing to separate valuable minerals from gangue.

 lMagnetic resonance imaging (MRI): The construction of MRI machines. The magnetic fields generated by the tiles help to produce high-resolution images of the human body.

 lLoudspeakers: Loudspeakers to produce a magnetic field that interacts with the voice coil to create sound.

 lWind turbines: The construction of wind turbines to generate electricity from wind energy. The tiles are used to create the magnetic fields that drive the turbines.

 lHard disk drives: Hard disk drives to create the magnetic fields that store data on the disk.

 lMagnetic couplings: Magnetic couplings to transfer torque between two shafts without any physical contact. This is useful in applications where there is a risk of contamination or leakage.

Overall, NdFeB magnetic tiles have a diverse range of applications due to their excellent magnetic properties.
