Abstract
The utility model discloses a kind of radial 12 pole magnet ring magnetizing clamps of permanent-magnet ferrite, including magnetizing clamp body, it is through-hole among the magnetizing clamp body, inside is equipped with 12 evenly arranged rectangular through-holes, bonds 12 pieces of neodymium iron boron kicker magnets in the rectangular through-hole.It is uniformly distributed one complete ten Dipole magnet field of composition by 12 pieces strong magnetic to compare with coil windings, low energy consumption and overcomes the defect of coil easy burn-out.
Description
Technical field
The utility model relates generally to a kind of mold more particularly to the radial 12 pole magnet ring magnetizing clamps of permanent-magnet ferrite.
Background technique
Permanent-magnet ferrite radial multi-pole magnetic ring is widely used in motor, this kind of magnet ring generally uses dry pressing to manufacture, by
Its magnetic orientation is disorderly and unsystematic after molding, it is therefore desirable to magnet ring is placed in high-intensity magnetic field and be orientated, the magnetic of all magnetic powders is made
Sexual orientation is consistent.In the prior art, mold cavity usually is added in permanent magnetic ferrite powder, while molding, existed to setting
The coil windings of die cavity periphery lead to high-frequency current, so that coil windings generate high frequency magnetic field and are orientated to the slurry in die cavity,
And suppressed, the intracavitary slurry of type be easy to cause Density inhomogeneity, the shortcomings that deforming after product sintering.Due to coil around
The electric current of group is larger, and coil windings are easy to be burned, and influence the service life of mold.
Utility model content
The purpose of the utility model is to provide a kind of radial 12 pole magnet ring magnetizing clamps of permanent-magnet ferrite, by being built-in with
12 pieces of neodymium iron boron kicker magnets replace coil windings to generate stable, complete ten Dipole magnet field, overcome coil windings energy consumption
It is high and be easy the defect burnt out.
In order to solve the above technical problems, the technical solution adopted by the utility model is:
The radial 12 pole magnet ring magnetizing clamps of permanent-magnet ferrite, including magnetizing clamp body, the magnetizing clamp body centre are
Through-hole, inside are equipped with 12 evenly arranged rectangular through-holes, bond 12 pieces of neodymium iron boron kicker magnets in the rectangular through-hole.
Preferably, the magnetizing clamp body material is pure iron.
The utility model has the beneficial effects that:
The utility model structure is simple, is uniformly distributed by 12 blocks of strong magnetic of neodymium iron boron and constitutes a complete 12 pole magnetic
Field is compared with coil windings, is not needed energy consumption and is overcome the defect of coil easy burn-out.
Detailed description of the invention
Fig. 1 is the main view of the radial 12 pole magnet ring magnetizing clamps of permanent-magnet ferrite.
Fig. 2 is the top view of the radial 12 pole magnet ring magnetizing clamps of permanent-magnet ferrite.
In figure: 1 magnetizing clamp body, 2 neodymium iron boron magnetic bodies, 3 through-holes.
Specific embodiment
As shown, the radial 12 pole magnet ring magnetizing clamps of permanent-magnet ferrite, including magnetizing clamp body 1, the folder that magnetizes
It is through-hole 3 among specific 1, inside is equipped with 12 evenly arranged rectangular through-holes, bonds 12 pieces of neodymiums in the rectangular through-hole
Iron boron kicker magnet 2.
Preferably, the magnetizing clamp body material is pure iron.
This magnetizing clamp needs and permanent-magnet ferrite multi-pole magnet-ring molding die matches, in use, by magnetizing clamp
It covers on molding die, then molding die is placed in by the uniform magnetic field generated in the case where 12 pieces of neodymium iron boron kicker magnets act on again
It is suppressed on press machine, after compacting, takes out finished product.
It is uniformly distributed one complete ten Dipole magnet field of composition by 12 pieces strong magnetic to compare with coil windings, low energy consumption
And overcome the defect of coil easy burn-out.
Disclosed above is only specific implementation of the patent example, but this patent is not limited to this, for the general of this field
For logical technical staff, without departing from the principle of this utility model, the deformation made should be regarded as belonging to the utility model
Protection scope.
