Description
Technical field
The present invention relates to a kind of stator, the manufacture method of stator and permanent magnetic brushless.
Background technology
Permanent magnetic brushless is made up of stator and rotor, and wherein stator is mainly made up of stator core and stator winding, is turned
Son is made up of rotor permanent magnet and rotor core, and rotor structure pattern is varied, can be interior permanent magnets structure, surface
Formula magnet structure or plug-in type magnet structure.The axial length unshakable in one's determination of stator typically with rotor core axial length and rotor permanent magnet
Body axial length is equal.Current stator core is mostly constituted by laminating silicon steel material, stator tooth top, stator tooth body and stator iron
The axial length of core yoke is all identical (i.e. so-called motor two dimension magnetic structure).Stator winding pattern is varied, and it is fixed to be positioned over
In pilot trench.Due to unshakable in one's determination using silicon steel is laminated, winding overhang is located at stator core two ends, be only intended in connecting stator groove around
Group conductor, occupies axial space without producing energy converting between mechanical.Soft-magnetic composite material is used as a kind of New-type electric machine iron core stator
Material, due to material isotropism magnetic characteristic in itself and the die forming technique of iron core, can make electric machine stator iron tooth top
Axial length (i.e. electric machine iron core have three-dimensional magnetic structure) of the axial length more than tooth body, and rotor core and rotor permanent magnet
The axial length of body is identical with the axial length of stator tooth top.Therefore SMC (soft magnetic composite, soft magnetism are based on
Composite, i.e., the composite with soft magnetism sexual function being composited by soft magnetic ferrite and polymer matrix) forever
Magnetic brushless electric machine, the end axial length space of winding can carry out electromechanical energy in the presence of rotor permanent magnet magnetic field and turn
Change.Therefore the electric machine stator iron based on soft-magnetic composite material has three-dimensional magnetic structure, and the power for being favorably improved motor is close
Degree and torque density.
But, being currently based on the electric machine stator iron of soft-magnetic composite material has two kinds of structures, first, being all combined by soft magnetism
Material molding is formed, it is of course possible to which by the way of piecemeal molding, whole soft-magnetic composite material stator core is divided into several blocks of SMC iron
The heart is combined, as shown in figure 1, stator core is divided into the portions such as stator core yoke 2-1, stator tooth body 2-2, stator tooth top 2-3
The end of piecemeal molding, winding 3 is divided to be located in space of the stator tooth top axial length more than stator tooth body axial direction；Second, stator
Yoke 2-1 unshakable in one's determination is used and is laminated silicon steel material, and stator core tooth part (including stator tooth body 2-2 and stator tooth top 2-3) is using soft
Magnetic is composite material moulded to be formed, and soft-magnetic composite material stator tooth is embedded on silicon steel stator core yoke is laminated, as shown in Figure 2.
Soft-magnetic composite material has two, i.e. permeability low relative to the disadvantage for laminating silicon steel material and normal motor works
Iron loss is high in frequency range.Therefore no matter entirety SMC stator cores, or current soft-magnetic composite material with laminate silicon steel material
Built-up stator core, all needed because the permeability of soft-magnetic composite material is low increase permanent magnet consumption, so as to improve electricity
Machine manufacturing cost, all due to soft-magnetic composite material, iron loss is low and have influence on the operation of motor in motor normal operating frequency range
Efficiency, so as to have influence on motor power density and torque density raising (although motor is due to using soft-magnetic composite material
With three-dimensional magnetic structure, so as to have theoretic high power density and torque density).
If traditional permanent magnetism silicon steel rotor is elongated to vertically it is concordant with the end of winding 3, as shown in figure 3, then electricity
Machine overall dimensions are constant.But rotor 1 can enter stator terminal beyond the permanent magnet magnetic flux of the part of stator 2, a part along track 4
Portion so that end saturation；Due to laminating anisotropy of the silicon steel sheet along motor axial direction, casing is solid construction in addition, another portion
Dividing magnetic flux can enter solid casing along track 5, cause compared with lossy, cause the waste of permanent magnet.
