Neodymium Magnet Arc

Neodymium Magnet Arc

There are a few standard segment rotor magnets on the market for different motors and generators. Each motor manufacturer designs different products, so segment magnets for motor rotors need to be customized. Huajin Magnets Source Material Limited provides curved magnet segments in different sizes and orientations.

 Product Details 

What grades & shapes are available for neodymium magnets?

Grades N35, N38, N40, N42, N48, N50, and N52 ( M, H, SH, UH, EH, AH series ) are available for all shapes & sizes of NdFeB magnets.

  Magnetization Direction 

Common direction of magnetization showed in picture bellow: 

• Disc, cylinder and Ring shape magnet can be magnetized Axially or Diametricall.
• Rectangle magnets can be magnetized through Thickness, Length or Width.
• Arc shape magnets can be magnetized Diametrically, through Width or Thickness.     

  Thickness Magnetized                  Circumference Magnetized             SN Diametrically Magnetized           NS Diametrically Magnetized

 Grade & Coating 

Support all magnet plating , like Ni-Cu-Ni, Zn, Epoxy , Gold,  Silver etc.

• Neodymium magnets are made of Neodymium, Iron and Boron.  If left to the elements, the iron in magnet will rust.

To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated.

• There are a variety of options for coatings, but nickel is the most common and usually preferred. 

Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes  magnets much more durable than the more common single nickel plated magnets.

• Other options of coating are zinc, tin, copper, epoxy,silver and gold.

 Application 

Neodymium magnet arcs are primarily utilized in permanent magnet motors. They have an arc shape and can be magnetized spontaneously, which makes them an important component in the manufacturing of motors. Neodymium magnet arcs have a wide range of applications, including electric vehicle motors, industrial electrical equipment, automotive electrical systems, and more.

In electric vehicle motors, neodymium magnet arcs are typically utilized in the form of permanent magnet DC motors, which are highly efficient and lightweight, making them ideal for various electrical equipment. 

Additionally, neodymium magnet arcs are employed in the production of DC motors, which are essential in industrial and automotive electrical systems, including reduction motors, servo DC motors, and starter motors for automobiles and motorcycles.
