Neodymium arc magnets are also called Arc segment magnets, which are made by wire cutting of the block magnets. This type of segment magnets are commonly used in DC motors, both for rotors and stators.and other motors. The magnets arc length is 45 degrees.
These Magnets are plated with 3 layers of protective coatings – Nickel + Copper + Nickel (Ni-Cu-Ni). The highest grade of these products are N52, N48M, N44H, N42SH, N38UH and N35EH etc.
Applications of Neodymium Magnets
Magnetic separators
Linear actuators
Microphone assemblies
Servo motors
DC motors (automotive starters)
Computer rigid disc drives, printers and speakers
Neodymium Arc Magnet is a common type of neodymium magnet. These magnetic arc segments can be assembled together in iron housing to provide magnetic field for electromagnetic motors. Neodymium arc magnets are widely used in high performance motors and various other electronics. Please just feel free to send us an enquiry if you are looking for neodymium arc magnets, curved magnets, segment magnets, motor magnets or related magnets.
Tolerances
For as-pressed material, tolerance on the thickness (direction of magnetization) is +/– .005”. Other dimensions are +/– 2.5% or +/– .005”, whichever is greater. High-performance Sintered Neodymium Arc Segment Magnets N38SH
According to International Magnetics Association/Magnet Materials Producers Association (IMA/MMPA) standards, visual imperfections such as hairline cracks, porosity and minor chips are commonly found in sintered magnets. A chipped edge is considered acceptable if no more than 10% of the surface is missing. Cracks are acceptable as long as they do not extend across more than 50% of the pole’s surface.
Attributes of Neodymium Material
Very high resistance to demagnetization
High energy for size
Good in ambient temperature
Moderately priced
Material is corrosive and should be coated for long term maximum energy output
Low working temperature for heat applications, but higher levels of heat resistance materials are being introduced periodically.
Magnetizing and Handling
Neodymium magnets are very brittle and very strong magnetically. Therefore, it is crucial to handle these magnets with extreme care to avoid personal injury and damage to the magnets. Fingers can be severely pinched between attracting magnets. Magnets can chip if allowed to “jump at” an attracting object. It is highly recommended that when constructing rare earth magnetic assemblies, they be magnetized after assembly.
