Block magnet is generally specified according to the Length x Width x Thickness. The first two dimensions specify the pole face`s size of each magnet, then the last dimension detail the magnetization direction, or distance between the N pole and S pole. Block magnet can be further classified to rectangular magnet, slab magnet, cube magnet, and square magnet in accordance with the relationships of above three dimensions.

SmCo disc magnets are typically sized by diameter (D) and thickness (T). Samarium-cobalt disc magnets generally have a metallic appearance and do not require protective surface treatments due to their excellent corrosion resistance. In addition, SmCo disc magnets are also very resistant to demagnetization and therefore perform well at high or very low temperatures. The 5G circulator magnet is a representative application of samarium cobalt disc magnets in recent years.

Sm2Co17-based magnets are still playing an irreplaceable role in the permanent magnet industry due to its unique high temperature magnetic properties and superior magnetic stability, then it always serving to the high-speed motors, electronic communication, and aerospace. High energy product magnets are the important basis to accelerate miniaturization and high efficiency of the device. Thus, obtain high performance SmCo magnet has always been a goal since the advent of Sm2Co17.

Permanent magnet coupling is a non-contact type coupling, consisting of two magnets inside and outside, separated by an isolation cover in the middle. The inner magnet is connected to the driven part, and the outer magnet is connected to the power part. Using the attraction between the relative magnetic poles, the transmission of force and torque between the driving shaft and the driven shaft can be achieved without direct contact.

The magnetic rotor assembly is one of the representative magnetic assemblies, and the rotor assembly is composed of metal parts and permanent magnets. In fact, depending on the application, motor type and assembly process, sintered neodymium magnets, sintered samarium cobalt magnets, bonded magnets and sintered ferrite magnets can all be used in the rotor assembly. It should be noted that laminated magnets made with magnet segmentation technology can also be used in assemblies to reduce eddy current losses.

Magnetic stator assemblies is also a representatives magnetic assembly,consisting of housing and permanent magnet which similar like magnetic rotor assembly. Permanent magnets are mounted on the housing, then housing working as the magnetic yoke to a form a magnetic circuit.

As the third generation of rare earth permanent magnets, neodymium magnets are the most powerful magnets produced commercially. NdFeB arc magnets, also known as NdFeB arc magnets, are sintered neodymium magnets with unique shapes. Almost all NdFeB arc magnets are used in permanent magnet (PM) motors, generators or magnetic couplings Rotor and stator in the device.

NdFeB block magnet is available in a wide range of dimension, grade, and coatings. It is generally specified according to the Length x Width xThickness. The first two dimensions specify the pole face’s size of each magnet, then the last dimension detail the distance between the N pole and S pole, or magnetization direction. Block magnet can be further classified to rectangular magnet, slab magnet, cube magnet, and square magnet in accordance with above three dimensions. Operating temperatures of Neodymium block magnet vary among material’s grades and can be used for a huge variety of applications.

Neodymium disc magnets have become a preferred solution for a wide variety of industrial and civil applications. Neodymium disc magnet is typically measured by the diameter and thickness, then its thickness is always smaller than the diameter. The great majority of Neodymium disc magnet are axially magnetized and widely served various types of application, such as holding purpose and speaker magnet. Diametrically magnetized pattern is also available for circular magnet and most of diametrically magnetized Neodymium disc magnet are used as the sensor magnet. Production efficiency of Neodymium disc magnet has gained a remarkable development with the widely application of multi-wire sawing.
