Description

High coereive force magnet charger for permanent magnetic cup radial magnetization
The utility model belongs to electrician's magnet charger class.
In recent years, because permanent magnet uses in industrial or agricultural, large-scale popularization aspect scientific and technological, more and more to the requirement of the permanent magnet of high-coercive force.The permanent magnetic material of high-coercive force such as samarium cobalt permanent magnet (S mC 0) or neodymium iron boron (N dF eB) permanent magnetism etc. will make it have good permanent magnetism performance, promptly enough big residual magnetic flux density (B), and coercive force (H), the magnet charger that can produce high-intensity magnetic field is exactly a key equipment.At present to solid permanent magnetism (as cube, cylinder or the like) in one direction magnetize and annular permanent magnet in axial magnetizing, the general hollow toroidal winding of pulse power supply that uses magnetizes, be energy-conservation purpose, the permanent magnetism of the above-mentioned shape of high-coercive force had also to adopt the outer magnetic field of executing be that 2.0TeSla or higher C type electromagnet are as magnet charger.But to radially magnetize to permanent-magnetic clamp, general at present employing is magnetized with two opposite hollow toroidal windings of energising direction of pulse power supply, because hollow coil warming-up effect, when producing in batches, executing magnetic field outward has any problem greater than 1Tesla, to obtain the permanent-magnetic clamp of the radial magnetizing of high performance high-coercive force in batches, just become a more scabrous problem.
The purpose of this utility model will provide a kind of exactly and outer execute magnetic field energy and reach the permanent-magnetic clamp diametrical magnetization magnet charger that 2Tesla can manufacture high-coercive force.
