Neodymium Motor Magnet is available, it is mainly used in automatic control system and long range linear motion device, we are offering the length 100 – 700mm.
Neodymium magnet is widely used in magnetic motor and vehicle magnet applications, it is typically two to three times stronger than ferrite magnet, which results in greater performance from smaller, lighter motors.
Neodymium magnet is also used in electric car motor applications. From the motor that spins a DVD disc to the wheels of a hybrid car, neodymium magnet is used throughout the vehicle. Anyway, please the below points into consideration when Neodymium is used as a vehicle magnet:
Neodymium Motor Magnet Operating temperature: A low coercivity grade Neodymium magnet may begin to lose strength if heated above 176°F (80°C). High coercivity grade Neodymium Magnet (EH or AH) have been developed to function at temperatures up to 428°F (220°C) with little irreversible loss. The need for low temperature coefficient in neodymium magnet application has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade.
Corrosion: Neodymium magnet is vulnerable to corrosion, especially along grain boundaries of a sintered magnet. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles. This vulnerability is addressed by adding a protective coating to prevent exposure to the atmosphere. Nickel plating or three-layered nickel-copper-nickel plating are the standard methods, although plating with other metals or polymer and lacquer protective coatings are also available.
