Description
Technical field:
The present invention relates to the built-in permanent magnet motor rotor lamination structure that a kind of mixing laminates.
Background technology:
The rotor structure of magneto can be divided into surface-type, built-in and Lundell three class according to permanent magnet arrangement form.Wherein the permanent magnet of built-in rotor structure is positioned at internal rotor, the pole shoe that ferromagnetic material (normally lamination silicon steel sheet) is made is had between permanent magnet outer surface and stator core inner circle, thus contribute to utilizing reluctance torque to improve overload capacity and the power density of motor, and be easy to weak magnetism speed expansion.Therefore such rotor is extensively adopted by magneto.
But due to permanent magnet in built-in rotor wrap up by permeability magnetic material, thus all there is very serious leakage field phenomenon.Larger load must be born again for the magnetic bridge limiting leakage field between pole shoe simultaneously, therefore limit between the requirement of leakage field and the requirement improving rotor strength and just had the contradiction that cannot be in harmonious proportion.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Summary of the invention:
The present invention is the built-in permanent magnet motor rotor lamination structure providing a kind of mixing to laminate to solve above-mentioned prior art Problems existing.
The technical solution adopted in the present invention has: the built-in permanent magnet motor rotor lamination structure that a kind of mixing laminates, comprise the first rotor punching, permanent magnet, shop bolt and the second rotor punching formed by the silicon steel sheet split of four fan shapes, some the first rotor punchings mutually across a certain distance be plugged on shop bolt, some second rotor punchings are plugged between two the first rotor punchings, gap is left between adjacent two silicon steel sheets in every sheet second rotor punching, the first rotor punching is provided with the installation slotted eye connected with described gap, the installation slotted eye that permanent magnet is plugged on the first rotor punching is interior with in the gap of the second rotor punching.
Further, four second rotor punchings are provided with between adjacent two the first rotor punchings.
Further, be provided with some first through holes in described the first rotor punching and along the circumferencial direction of the first rotor punching, the first rotor punching is plugged on shop bolt by this first through hole.
Further, described silicon steel sheet is provided with the second through hole, and the second rotor punching is plugged on pin by this second through hole.
