Description
Technical field
The invention belongs to the preparation method of technical field of motor manufacture, more particularly to amorphous alloy stator iron core.
Background technology
Amorphous alloy material have magnetic conductivity is high, exchange core loss it is low (core loss for traditional silicon steel sheet ten/
1/1 to five) the advantages of, in Industrial Frequency Transformer, industrial frequency reactor, radio-frequency rector and transformer, high-speed electric expreess locomotive or multipole
The application in the high-frequency electric machines field of logarithm is got growing concern for.For example high speed and precision grinding machine motor pole number is 4, rotating speed
For 36000r/min, the alternative frequency of fundamental wave magnetic field is 1200Hz in stator core；Driving motor for electric automobile, number of poles 10,
Stator current frequency is 1000Hz when rotating speed is 12000r/min.High-speed electric expreess locomotive or high-frequency electric machines use amorphous alloy material conduct
Stator core makees stator core than silicon steel sheet can substantially reduce core loss, improve electric efficiency.But amorphous alloy material
More sensitive for mechanical stress, excessive mechanical stress can substantially reduce the magnetic conductivity of amorphous alloy material when processing or assembling
Energy.
The stator core of traditional silicon steel sheet motor typically extrudes two in the cylindrical punching press of stator punching and arrives multiple breach,
Multi-layer stator punching is applied in the axial direction will by the method being welded in outer discount vibram outlet mouth in the case that certain pressure laminates
Multi-layer stacks are fixed into complete stator core.
Also shaping stator iron core method be silicon steel punched chip it is cylindrical on be uniformly distributed and stamp out multiple dovetail grooves, it is more
Layer stator punching is laminated as stator core, and the narrow steel plate of elasticity is axially penetrated in dovetail groove, in stator core end by elasticity
Narrow steel plate bending, which turns into, compresses cramp, is a complete stator core so as to which multi-layer stator punching be compressed.
Or for the somewhat larger motor of stator outer diameter, it is uniformly distributed on stator punching is cylindrical and stamps out 6 or more
Individual rectangular slot, multi-layer stator punching laminates places steel annular as stator core, stator core both ends close to cylindrical place
Pressure ring, narrow steel plate is put into the axial rectangular slot of stator core, outside the annular pressure ring at both ends by narrow steel plate bending simultaneously
Overlapped with pressure ring, in the case where applying certain axial compressive force to annular pressure ring and stator core, by being welded narrow steel plate
Welded with end circular loop shape pressure ring, so that stator core both turns into an entirety, meet that certain stacking factor will again
Ask.
These three modes compress stator punching and the defects of certain all be present, and either electric welding line or stator compresses
All equivalent to mouse cage sliver for narrow steel plate in cramp, or the axial rectangular slot stray field cylindrical to stator core,
The electromotive force with the same frequency of stator winding can be produced, and direct and stator punching or the steel annular pressure ring at stator both ends are short
Connect, extra electric current is formed between stator punching, increase the eddy-current loss of stator core.In order to avoid stator cramp is with determining
The contact of sub- iron core, increase extra eddy-current loss, have makes cramp with determining by the way of cramp set insulation sleeve is compressed to steel
Sub- iron core is not directly contacted with.
For the higher silicon steel sheet motor of performance requirement or prototype design stage, first with the acetal diluted by absolute ethyl alcohol
Resin brush every silicon steel sheet it is two-sided it is each twice, multi-disc silicon steel sheet is pressurizeed with fixture after drying and kept at a certain temperature
Certain time is solidified, and turns into complete stator core by wire cutting afterwards.But acetal resin belongs to organic resin, most
High-temperature is 155 degrees Celsius, is not suitable for the heat treatment of 350 degrees Celsius of non-crystaline amorphous metal and the above.
The assembly method of traditional silicon steel sheet stator core and electric machine stand and cooling jacket is on support or cooling jacket
Radially installed one or more screw jackscrew is directly to the cylindrical application radial load of stator core, to prevent the sub- iron core axial direction of fastening and footpath
To vibration.
