Magnetic assemblies are equipped with permanent magnets like NdFeB magnets and other material parts like metal, stainless steel, plastic, rubber, adhesive tape, wood, hardboard and etc. Magnet assemblies can be much more powerful than magnet itself, and achieve some certain functional effect which magnet cannot meet.

A Halbach Array is a special arrangement of permanent magnets that makes the magnetic field on one side of the array stronger, while canceling the field to near zero on the other side. Halbach array magnets for sale are very different from the magnetic field around a single magnet. With a single magnet, you have an equal strength magnetic field on either side of the magnet.

Applications of Halbach Arrays

• Halbach Array is most commonly used to produce a magnetic field utilizing permanent magnets arranged in a 90° orientation change between magnetic elements, which amplifies the magnetic force.
•  Planer Halbach Arrays are typically used for holdings, fixturing, linear coupling applications, etc.
• Circular Halbach Arrays (OD iteration) can be used in rotors for brushless DC motors, magnetic couples, power generations, etc.
• Circular Halbach Arrays (ID iteration) are used to constrain plasma, steer, sort and accelerate moving charged particles, and impart oscillations.

Where are Halbach Arrays actually Used?

Halbach Array is most commonly used to produce a magnetic field utilizing permanent magnets arranged in a 90° orientation change between magnetic elements, which amplifies the magnetic force.

Halbach Arrays can also be configured in other shapes. A halbach array ring magnet with multi-pole magnetization or a ring made up of smaller arc segments can be used in this way.

NBAEM automates rotor and stator production. A permanent magnet motor consists of two basic parts: a stator coil and a rotor. A stator coil which is powered by an alternating current, creates an electric filed. A rotor made of permanent magnets rotates within that field. An AC motor that uses magnets is imbedded into or attached to the surface of the motor’s rotor.

Magnetic rotor or permanent magnet rotor is the non-stationary part of a motor. As one of the most representative magnetic assemblies, rotor assemblies are consisting of iron part and permanent magnet. Sintered Neodymium magnet, sintered Samarium Cobalt magnet, bonded magnet and ferrite magnet are all can be utilized to rotor assemblies according to different application, motor type and assembly process. It should be pointed out that laminated magnets made by magnet segmentation technology are also served to assemblies to decrease the eddy current loss.

The rotor is the moving part in an electric motor, generator and more. Magnetic rotors are designed with multiple poles. Each pole alternates in polarity (north & south). Opposite poles rotate about a central point or axis (basically, a shaft is located in the middle). This is the principal design for rotors. It is used in the In-wheel motor of electric sport car. NBAEM offers high performance permanent magnet motor components and sub-assemblies for aerospace and defense, industrial, automotive, and motorsport applications.

Magnetic stator assemblies are consisting of housing and permanent magnet which similar like magnetic rotor assemblies. Permanent magnets are mounted on the housing, then housing working as the magnetic yoke to a form a magnetic circuit. Besides conventional magnetic stator assemblies which used sintered Neodymium magnet, bonded magnet, and the ferrite magnet, NBAEM is also able to provide linear motor stator assemblies and latest axial flux motor assemblies to our valued customers

Precast Concrete is considered as the latest generation of commercial building material which gradually replacing traditional site-cast concrete in recent years. Precast concrete has been widely by the construction industry owing to its flexibility, durability, and economic efficiency. As an indispensable accessory of precast concrete system, precast concrete magnets are utilized to fix different embedded parts during pouring process of concrete. Precast concrete magnet can be further classified into shuttering magnet, insert magnet and magnetic chamfer according to their specific usage scenario.

Advantages of Precast Concrete Magnets

• Labor and material cost will substantially reduce, and installation efficiency will be also enhanced in the meanwhile.
• Very easy and precise positioning.
• The positioning stage is free of screw, bolt, and welding, then stainless-steel plate can avoid damage.
• Reuse can be achieved. Thus keep long service time and shorter payback.
• Environment of the construction site will be strongly enhanced and simultaneously ensure safety of construction personnel.

Shuttering Magnet for Precast Formwork Introduction.
Precast concrete magnets are very popular in modern civil engineering. In the past 5 years, some conventional magnets were used to position and fasten the formwork, but considerable
mechanical loads with a hammer were required, which destroy the surface of the expensive formwork tables and fragile neodymium magnet as well.

In order to facilitate the precast concrete formwork industry, NBAEM is developing and manufacturing our own shuttering magnet to solve this problem successfully.
Our shuttering magnet also is known as button magnets and magnetic boxes. It is consists of a metal casing, a magnetic system, and an effective on/off button, which provides quick operation leading to improved efficiency when setting out and remove the formwork. And with customized adaptors, shuttering magnet provides an ideal solution for almost all kinds of precast concrete formwork structures and construction for wood, aluminum, and steel shutters.
The NBAEM shuttering magnet have an automatic system to activate and deactivate the magnetic field. By application of this precast magnet box, the working time and cost will be reduced and the same workers could produce more concrete walls in a shorter time. Under the same artificial conditions, the use of the shutter magnet system can increase the production capacity by 7 times
