Features of Arc NdFeB Magnet

Neodymium arc magnets, or neodymium segment magnets, can be seen as a part of neodymium ring magnets or neodymium disc magnets.They are made of high-quality neodymium magnets containing the elements neodymium, iron, and boron. Neodymium arc magnets aremostly used in voice coil motor, permanent magnet motors, generators, wind turbines, torque couplings, and other applications.

Magnetization Orientation

Neodymium curved 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 arc magnet is extremely difficult to manufacture. Fan-shaped arc 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.

Typical Coatings

Plating neodymium magnets is an important process to protect the magnet against corrosion. The typical coating for a neodymium magnet is Ni-Cu-Ni coating.Some other options for coating are zinc, tin, copper, epoxy, silver, gold and more.

Q1. Why neodymium magnets are used for motors?

A1. The latter is one of the most commonly used in motors for hybrid vehicles and electric vehicles. Neodymium magnets have higher remanence, along with much higher coercivity and energy production, but often a lower Curie temperature than the alternatives.

Q2. What is arc magnet?
A2. Arc magnets are a unique shape which are designed especially for motors, generators and alternators and are commonly used for both rotors and stators. They are also used in magnetic flywheel assemblies.

Q3. What is arc or crescent magnets?

A3. Crescent magnet is a special shape of rare earth magnet with difficult and complex manufacture craft, and crescent magnets are also called neodymium arc magnet, it is made by wire cutting of the block magnets.

Q4. What are arc magnets used in?

A4. Top Quality Rare Earth Neodymium Arc Magnets are typically used in permanent magnet motors, generators and torque couplings. However, these may be found with sensors and holding applications.

Q5. Why are curved magnets used in DC motors?

A5. It conducts the current which interacts with the magnetic field to provide torque. The magnets form the stator as either permanent magnets or electromagnets. They are on opposing sides of the rotor and are usually curved (radial) to provide a uniform magnetic field to the coil.
