These high-performance Neodymium (N42) arc magnets are commonly used in motors for both rotors and stators. They feature an anisotropic alignment and a maximum operating temperature of 80C. The dimensions are 25mm high x 4mm thick, with an outside radius of 37.5mm and an inner radius of 33.5mm. The magnet's south pole is on the inside radius and the north pole is on the outside radius. Four of these south arc magnets with four of the north version are required to create a 360o 8-pole ring. The magnets are coated with three layers of nickel, copper, and nickel to reduce corrosion and provide a smooth and clean finish.
