Description
Technical field
The present invention relates to a kind of radial magnetic field motor with amorphous alloy material.
Background technology
Amorphous alloy is a kind of novel soft magnetic material of being born in the seventies in 20th century.Roughly has the molecular formula of using A
70-85B
5-20C
0-20Expressed composition.Subscript is represented the shared percentage of different elements, and wherein A represents at least a in iron, nickel and the cobalt; B representes in boron, carbon and the phosphorus at least a; C representes in silicon, aluminium and the germanium at least a.Amorphous alloy is compared with traditional silicon steel material has many-sided advantage, and its core loss is extremely low, particularly when the magnetic field alternative frequency very high, during such as 0.5kHz～20kHz, this low-loss characteristic is more obvious.Therefore, amorphous alloy is fit to the motor that manufacturing has high efficiency, high-speed cruising and compact volume requirement very much.Described motor indication is a generalized concept, the motor of making a general reference various forms of generators, motor and having the regenerative braking ability.Yet the amorphous alloy extreme hardness is about 3 times～5 times of silicon steel sheets, directly uses the extremely consumption punch die of speed of conventional Sheet Metal Forming Technology processing amorphous alloy material, makes processing cost rise.Provided in very thin tape form amorphous alloy material thickness the most commonly used has only 0.03mm, is about 1/10 of general silicon steel sheet; If copy silicon steel plate stacking technology a slice a slice to laminate amorphous alloy ribbon, not only the time grows up to this height, and the stacking factor that obtains is also very low.Simultaneously this material working temperature is low, has the processing technology that high temperature follows characteristic with line cutting and welding etc. and all can cause material " recrystallization ", even this recrystallization is local, to material behavior, also can cause tremendous influence like loss etc.Just because of above-mentioned several respects reason,, can not directly apply to conventional radial magnetic field structure motor easily though make amorphous alloy material have excellent electromagnetic performance.
Many scholars and technical staff have proposed the amorphous motor of the different structure of suitable non-crystalline material processing.
Chinese patent CN201010121452.7 has proposed a kind of horizontal magnetic field motor with amorphous alloy iron core.Stator core is made up of a plurality of unit motor stator core.Each unit motor stator is uniformly distributed along the circumference by Q U type amorphous alloy iron core and forms, and the opening portion of Q U sections core constitutes the stator slot perpendicular to armature spindle, and this structure is not suitable for the radial magnetic field motor.U type amorphous alloy iron core adopts amorphous band to roll and forms, and single U sections core constitutes a complete loop.The U sections core opening portion of each unit motor constitutes the tubular stator slot of this horizontal magnetic field motor amorphous stator, has significantly reduced the stator core manufacturing procedure, has avoided processing technology to the non-crystalline material Effect on Performance.And this transverse magnetic field amorphous motor can easily enlarge the power and the size of motor, has avoided the restriction of the barbed width of amorphous to amorphous stator core size.Yet this electric machine structure is a horizontal magnetic field motor, and its amorphous stator core is not suitable for the conventional radial magnetic field electric motor.
Patent of invention US5731649 has proposed a kind of mode that amorphous alloy ribbon is made the motor in axial magnetic field stator core that rolls.Stator is combined by a series of cylinders in its invention.Cylinder is divided into two kinds, first kind of tooth as stator, and another kind of yoke as stator.All cylinders as tooth all are connected with the cylinder of regarding yoke, to form complete flux path.Two kinds of cylinders all use amorphous alloy ribbon form concentric spirals formula to reel and form.
Electric machine structure is respectively horizontal magnetic field motor and motor in axial magnetic field among patent CN201010121452.7 and the patent US5731649, and its amorphous stator can not be applicable to the conventional radial magnetic field electric motor.Therefore scholar and technical staff have proposed the method for different processing radial magnetic field motor amorphous stator cores, to adapt to the special mechanical performance of amorphous alloy material.
Chinese patent CN200810007282.2 and CN200910105338.2 have set forth the scheme that amorphous alloy material is made the radial flux motors stator core of using from different perspectives.
A kind of preparation method who is used for the radial magnetic field amorphous alloy stator core of high-speed electric expreess locomotive is disclosed among the CN101286676A.Amorphous alloy strips is cut into a plurality of amorphous alloy films with predetermined length; Laminate and form the range upon range of rod of amorphous alloy film with predetermined thickness; Said range upon range of rod is annealed; Said range upon range of rod after the annealing solidifies with binder-impregnated, cuts said range upon range of rod at last, forms the stator core of required form and size.Simultaneously, because amorphous alloy material is very suitable for conventional radial magnetic field structure motor being overrided to form along axial direction unshakable in one's determination.But because the mode of using axial direction to stack amorphous thin ribbon is one by one made iron core, the iron core size is limited by strip width, and can not avoid long processing time, shortcoming that cost is high.
CN200910105338.2 has proposed the method for modularization making radial magnetic field motor amorphous alloy stator; Break away from integral cutting and prepare the shortcoming that the amorphous alloy stator receives the Breadth Maximum restriction of amorphous alloy strip steel rolled stock, make amorphous alloy stator iron core be applicable to the motor that diameter is bigger.The amorphous alloy laminated stack that amorphous alloy strip steel rolled stock is processed; Along range upon range of thickness direction; Said amorphous alloy laminated stack is cut into tile arc cylinder body with radial thickness; And cut out the groove position that is used to embed winding at this arc cylinder inner body surface, thus process the amorphous alloy stator modules, the composite joint of N amorphous alloy stator modules is become a complete annular stator core.Though this method has solved the amorphous stator core and has received the shortcoming of strip width restriction, but still can not avoid long processing time, the shortcoming that cost is high.
