Neodymium Motor Magnets

Name: Neodymium Motor Magnets
Brand: Ningbo Beilun Meank Magnetics Co.,Ltd.

The permanent magnets used for motor are give the name of motor magnets.For shape,most of motor magnets are in arc shape;for material,all ferrite motor magnets, SmCo motor magnets and neodymium motor magnets are available.Beilun Meank is excellent on neodymium motor magnets processing.

Surface Treatment is Required on Neodymium(NdFeB) Motor Magnets

Neodymium(NdFeB) magnet material is not rust-resistant and easy to corrode, so protection coating needed for the surface of neodymium(NdFeB) motor magnets, Zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel,epoxy coating are usually adopted on neodymium motor magnets.

Magnetization Direction of Neodymium (NdFeB) Motor Magnets

According to the application,the magnetized direction of neodymium(NdFeB) motor magnets is divided into radially magnetized and diametrically magnetization.Please let us know the magnetization direction when you send us inquiry for rare earth neodymium motor magnets

Custom Rare Earth Neodymium(NdFeB) Motor Magnets

Motor magnets are custom industry magnets, Nd-Fe-B material has good machinability and can be customized into different types of motor magnets, while mould is not necessary.You can get all neodymium arc type motor magnets for all industry .The drawings are needed when you inquiry and order rare earth neodymium motor magnets.
