Bonded Neodymium Magnets, also known as Bonded Neo-Magnet, are made from Neodymium Iron Boron (NdFeB) powder and a polymer bonding agent. They come in a variety of shapes, including discs, blocks, cylinders, rings, etc. and can be customized to fit specific applications. The minimum order quantity (MOQ) is 100 pieces and the maximum operating temperature is 120°C-150°C. These magnets are used in a variety of motors, such as spindle motors, stepping motors, synchronous motors, DC motors and brushless motors. Bonded Neodymium Magnets provide strong magnetic force, excellent corrosion resistance, and are a great cost-effective solution for many motor applications.
