Magnetic base manufacturing equipment according to embodiments of the present invention further comprises：One press unit, is configured to the receiving
The magnetic accommodated in unit is suppressed, wherein, the orientation unit is suppressed the magnetic in the press unit
While, the magnetic is orientated.
So, due to compacting be used for manufacture magnetic base magnetic while, the magnetic in the magnetic field produced by orientation unit
The line of force can directly pass completely through downtrodden magnetic, and the magnetic that suppressed sufficiently can be orientated,
So as to lift the performance of the magnetic base produced.
Below, magnetic base manufacturing equipment according to embodiments of the present invention will be more particularly described with reference to Fig. 2.
Fig. 2 is the schematic diagram of the example for the manufacturing equipment for showing ring-type magnetic base according to embodiments of the present invention.
As shown in Fig. 2 in the magnetic base manufacturing equipment for manufacturing ring-type magnetic base, the housing unit 110 is specific
For annular die, to accommodate the magnetic to be suppressed.Also, the orientation unit 120 is specially to be installed to ring-type
The periphery of mould is with the coil 3 of the circular annular die.As shown in Fig. 2 the coil 3 is arranged in annular die
Around the outer perimeter of tool, and there is common central shaft 1 with the annular die.The annular die can be wrapped specifically
An inner-diameter portion 2 is included, the inwall for limiting the magnetic chamber 5 for accommodating the magnetic to be suppressed.Also, the ring-type
Mould can comprise additionally in outer radius portion 4, the outer wall for limiting the magnetic chamber 5 for accommodating the magnetic to be suppressed.
Certainly, although it will be understood by those skilled in the art that not shown in fig. 2, the annular die should be wrapped
Base section is included, so as to limit the bottom wall for the magnetic chamber 5 for accommodating the magnetic to be suppressed.Here, this area skill
Art personnel are appreciated that orientation unit is installed to housing unit and can directly connect with housing unit including orientation unit
Touch, for example, coil 3 directly contacts the outer radius portion 4 of the ring mould, can also be separated by a distance therebetween,
Will as long as the distance magnetic line of force to ensure the magnetic field produced by orientation unit short enough can be passed completely through directly
The magnetic of compacting.It is noted that the size by adjusting the inner-diameter portion, the ring-type magnetic base it is interior
Footpath is also adjusted.It is noted that the inner-diameter portion 2 is removably arranged at the magnetic chamber 5.If should
The inner-diameter portion 2 is not set in magnetic chamber 5, then the magnetic base manufacturing equipment is used for the magnetic base for manufacturing column.If
One rotation section for being used for motor rotor is arranged at the magnetic chamber 5, and the magnetic base manufacturing equipment can be manufactured for electronic
The magnetic base of machine rotor.Center line for the rotation section of motor rotor aligns the central shaft 1.
In addition, although be installed to figure 2 illustrates the orientation unit around the outer perimeter of housing unit, i.e. will
Coil 3 is arranged in around the outer perimeter of annular die.But coil 3 can equally be arranged in the inner circumferential of annular die
Around boundary, for example, be arranged within the inner-diameter portion 2 of annular die, and be in contact with the inner-diameter portion 2 or
Approximately it is in contact.Similarly, the magnetic line of force in the magnetic field produced by the coil 3 arranged in this way also can be direct
Ground passes completely through the magnetic to be suppressed.That is, in magnetic base manufacturing equipment according to embodiments of the present invention,
Orientation unit " circular " housing unit is not limited in outside the outer perimeter of housing unit around housing unit
Mode.

In addition to being arranged in the coil around compacting tool set.As shown in figure 3, the requirement of ring-type magnetic base is 4 grades, so,
24 coils in coil 3 are divided into 4 groups, using 6 adjacent coils as one group.Also, it is every group of line
The different phase of circle distribution.Two groups of wherein adjacent coils are mutually anti-phase.So, when coil 3 is for being contained in
When the magnetic to be suppressed in magnetic chamber 5 applies magnetic field, the orientation of the magnetic to be suppressed in magnetic chamber 5
4 poles are fixed as requested, as illustrated, dark is centripetal pole, light color is centrifugation pole.
Using magnetic base manufacturing equipment according to embodiments of the present invention, it can to obtain for manufacturing the magnetic of magnetic base
Sufficient orientation and compacting, make manufactured magnetic base have desired magnetic pole distribution, so that manufactured by being lifted
The performance of magnetic base.
