The position of magnetic pole is multiple and there are four common situations,such as:the outer ring(one or multiple),the inner ring(one or multiple),the two ends of ring above and below(一N一S), the one end of ring above or below(one or multiple).

Ring Magnet


1.Dimension:the max of outer diameter is 150mm(≤150mm);

                      the max of inner diameter is 100mm(≤100mm);

                      the max of height is 65mm(≤65mm) ;

The specific size is according the customers’ requirement.


2.Materials: Sintered Neodymium-Iron-Boron


3.Grade:N35 and N40 are the normal grades,can satisfy the normal applications.The grade of N48 ,N50 and N52 can meet the demand of strong power.


4.Coating:Nickel, Zinc, Gold, Silver, Epoxy, etc.(according to the usage)


5.Characteristics:Ring magnet is made of hard magnetic materials.Ring magnet is magnetic until they are magnetized.The position of magnetic pole and the number of magnetic poles depend on magnetization. The specific usage and the number of poles are based on the customer.


6.Applications:Wind generators or turbine,motors,sensors, etc.
