Arc magnets can be seen as a part of ring magnets or disc magnets. Sometimes arc magnets are called as segments magnets. Neodymium arc magnets are mostly used in electronic machines, equipments, permanent magnet motors, generators, rotors, stators, couplings, wind turbine and other applications. These products will generate a lot of heat and energy in high speed running. So the built-in arc magnets have to withstand high temperature in operating.
