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
