Description
Technical field
The present invention relates to permasyn morot technical field, especially a kind of permanent magnetism of Ru-Fe-Mn's permasyn morot
The buffering polyunit of rotor.
Background technique
With the invention of needs and electric current magnetizing apparatus that various motors rapidly develop, mechanism of the people to permanent-magnet material, structure
It is had made intensive studies at manufacturing technology, has found carbon steel, wolfram steel (maximum magnetic energy product about 2.7kJ/m3), cobalt steels in succession (most
Big magnetic energy product about 7.2kJ/m3) etc. a variety of permanent-magnet materials.Al-Ni-Co permanent magnet (the maximum magnetic energy especially occurred the 1930s
(maximum magnetic energy product is existing up to 40kJ/m3), and magnetic property has very for the ferrite permanent-magnet that product occurs up to 85kJ/m3) and the fifties
Big to improve, various miniature and micro-machine uses permanent magnet excitation one after another again.The power of magneto as low as counts milliwatt, big to several
It ten kilowatts, is used widely in military, industrial and agricultural production and daily life, yield sharply increases.Correspondingly, this period
In the design theory of magneto, calculation method, magnetize and in terms of also all achieve breakthrough, form
Using permanent magnet working drawing graphical method as a set of analysis and research method of representative.But the coercivity of Al-Ni-Co permanent magnet it is relatively low (36~
160kA/m), the residual flux density of ferrite permanent-magnet is not high (0.2~0.44T), limits their application ranges in motor.One
Until the 1960s and the eighties, rare-earth cobalt permanent magnet and Nd-Fe-B permanent magnetic (the two general designation rare earth permanent magnet) are come out one after another, it
High residual flux density, high-coercive force, high energy product and linear demagnetizing curve excellent magnetic can particularly suitable for manufacturing motor,
To make the development of magneto enter a new historical stage.
Permasyn morot and normal asynchronous are not both rotor structure, are equipped with permanent magnet magnetic on rotor
Pole, PM rotor iron core are still needed to silicon steel sheet stack at convex type p-m rotor is only equipped with hole location at center, right in the prior art
The problem of silicon steel sheet offset is easy to appear when silicon steel sheet is laminated, and be that pressure head directly contacts silicon steel sheet in the prior art,
Silicon steel sheet pressure moment reaches maximum, lacks buffering, exacerbates the offset of silicon steel sheet.
