Product Descrption:
NdFeB Neodymium Magnets 22.5 degree 14" OD x 8" ID x 0.5" thick Wedge Segment
These rare earth ndfeb neodymium magnets are used for building efficient and powerful wind generators.
Wind generators built with these wedge magnets have better performance than the wind generators built with block magnets
Huge wind generator magnets !
2.64" at the wide end, 1.57" at the narrow end, 3" long, 0.5" thick
16 pieces of these wedge magnets can form a ring of 14" OD x 8" ID x 1/2" thick
Grade N42 super strong ndfeb neodymium magnets
Magnetized through the thickness, poles are on the flat surfaces
NdFeB Neodymium magnets are the world's strongest magnets. All magnets are not created equal! Applied Magnets offers the highest quality NdFeB neodymium magnets with consistent performance at lowest price. Our strong NdFeB neodymium magnets are designed & manufactured to meet stringent quality standards using the latest technology.
Neodymium magnets (also known as Neo, NdFeB, NIB or super magnets) , a type of rare earth magnets, are the permanent magnets made from neodymium, iron, boron and other minor elements.

Product Name: Motor Magnet, Segment, Arc ndfeb magnet, Arc Magnets.Tile NdFeB Magnet
It is one special shape of Rare earth magnets and permanent magnets. It is always manufactured via Wire Cutting and grinding etc. Regular Arc magnets or Segment magnets have the following important factors such as, Outer Diameter or Outer Radius, Inner Diameter or Inner Radius, Degree of Angle, Thickness, Length, Round Edge etc.
Applications:
Motors, eg. voice coil motor (VCM),step motor, geared down motor, etc.
Features:
Generally speaking, Arc Magnets are all made as Customer Design and as Special requirement. Our factory production and manufacture magnets according to customer's design on shape, dimension, grades, coatings etc.
Magnets grade: From N35 to N50, from N Series to UH Series.
Magnets drawing with size and shape and different side view
Magnetism direction: Mostly magnetized via diameter, if special magnetism direction, please show on the drawing in advance.
Magnets coating: Nickel, Zn, Black Epoxy, Black Nickel ,Nickel -Cu-Nickel,Ag, Au etc.
Quantities: More mass order quantities. More lower the prices. Original manufacture.
