Abstract
The utility model provides a magnet, in particular to a neodymium-iron-boron magnet with an epoxy layer used for a motor. The neodymium-iron-boron magnet comprises a magnet that comprises an intermediate layer and an epoxy layer, wherein the outside of the intermediate layer is wrapped by the epoxy layer. The neodymium-iron-boron magnet has simple structure, suspends oxidation and prolongs the service life.
Description
Technical field
The utility model is a kind of magnet, particularly a kind of neodymium iron boron magnetic that has epoxy layer that is used in motor-driven electricity.
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, can't adapt to multiple demand.
Summary of the invention
Utility model mainly is to solve the deficiencies in the prior art, and a kind of neodymium iron boron magnetic that has epoxy layer 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 that has epoxy layer comprises magnet, and magnet comprises intermediate layer and epoxy layer, and described intermediate layer is coated with epoxy layer.Epoxy layer can keep magnet not oxidized, delays oxidization time, guarantees useful life.
As preferably, described epoxy layer is a black powder.
As preferably, described magnet is a neodymium iron boron.
As preferably, the thickness of described epoxy layer is 0.3～0.5mm.
Therefore, the neodymium iron boron magnetic that has epoxy layer that the utility model provides, simple in structure, delay oxidation, increase the service life.
Description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model.
