Arc Shape Neodymium Magnets for Motor

Custom Arc segment neodymium crescent/arc/tile magnet for motor wind generators

Neodymium arc magnets are some of the most powerful permanent magnets available today. Made from a combination of neodymium, iron, and boron, these magnets are highly resistant to demagnetization and provide a lot of magnetic strength in a small size. Due to their unique arc shape, these magnets are often used in motor and generator assemblies, as well as in speakers, sensors, and a variety of other high-tech applications. They can be used to produce very strong magnetic fields, making them ideal for applications where high power and accuracy are required.

At BEARHEART, we specialize in manufacturing high-quality neodymium arc magnets that are designed to meet the specific needs of our customers. Our magnets are made using advanced manufacturing techniques and materials, which ensures that they are both reliable and long-lasting. Contact us today to learn more about our products and how we can help you meet your unique magnet needs.

Product details

Features of Arc NdFeB Magnet As the third generation of rare earth permanent magnet, Neodymium magnets are the most powerful commercially produced magnets. Neodymium arc magnet, also known as Neodymium curved magnet, is a unique shape of Neodymium magnet, then almost all of Neodymium arc magnet is used for both rotor and stator in permanent magnet (PM) motors, generators, or magnetic couplings.
	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.

FAQ: 

Q1. What magnets are used in motor?

A1. Most electric motors are made from ceramic, alnico, neodymium (NdFeB) or samarium cobalt (SmCo) magnets.

Q2. How does a magnet work in a motor?

A2. Magnets are a primary component in electric motors. In order to work they need to be made of a coil of wire that can spin and is encircled by strong magnets. When an electric current is induced in the coil, it emits a magnetic field, opposing the magnetic field emitted by the strong magnets.

Q3. What is the best magnet for a motor?

A3. Samarium Cobalt (SmCo) magnets are optimal for high temperature motor applications due to their high magnetic strength, exceptional temperature resistance, and reliable performance without oxidation protection. Corrosion Resistance: SmCo magnets offer outstanding corrosion resistance (neodymium magnets do not).

Q4. Are permanent magnet motors AC or DC?

A4. A permanent magnet (PM) motor is an ac motor that uses magnets imbedded into or attached to the surface of the motor's rotor.

Q5. What is motor magnetic?

A5. A magnet motor or magnetic motor is a type of perpetual motion machine, which is intended to generate a rotation by means of permanent magnets in stator and rotor without external energy supply. Such a motor is theoretically as well as practically not realizable.
