Abstract
The utility model relates to a magnetic body, in particular to an NdFeB (neodymium iron boron) magnetic body used for motors, sensors or wind turbine generators. The magnetic body comprises a copper layer, wherein nickelous layers are plated outside the copper layer and fixedly connected with the copper layer in a matched manner. The magnetic body has the advantages of simple structure, stable magnetic property and high assembly accuracy.
Description
Technical field
The utility model is a kind of magnet, particularly a kind of neodymium iron boron magnetic body that is used on motor, transducer or the wind-driven generator.
Background technology
The magnetic instability of magnet of the prior art, and magnet damages easily, causes and can't use, and influences operating efficiency, and the magnet assembling is poor simultaneously, can not join with used product essence.
Summary of the invention
Utility model mainly is to solve the deficiencies in the prior art, and a kind of neodymium iron boron magnetic body that is used on motor, transducer or the wind-driven generator is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of neodymium iron boron magnetic body, magnet comprise the copper layer, and the copper layer is coated with nickel dam outward respectively, and described nickel dam is complementary with the copper layer and fixedlys connected.Guarantee the magnetic stability of magnet, improve assembly rate, the class and the useful life of improving institute's assembled product simultaneously.
As preferably, described nickel dam coats the copper layer.Behind nickel coating, magnet is magnetized the magnet after feasible the substituting the bad for the good, stable performance.
As preferably, the thickness of described copper layer is 5～8um, and the thickness of described nickel dam is 5～8um, and the gross thickness of described magnet is 15～25um.
As preferably, described magnet is a cuboid.
Therefore, a kind of neodymium iron boron magnetic body that the utility model provides, simple in structure, magnetic stability, assembly precision height.
