The utility model is tested by practical use; the mechanical strength of the steel magnet is reliable and the magnetic property thereof is 30% higher than that of a common rotor; the use requirement can be better met after the high and low temperature reliability test; and the utility model has the advantages of excellent use value and economic benefits.
Description
Technical field:
The utility model relates to a kind of electrical micro-machine, particularly relates to the fixed structure of a kind of electrical micro-machine with the rotor permanent magnetic steel.
Technical background:
In the prior art, magnet steel is very common as the magnetic pole of rotor, but traditional magnet steel generally adopts the mode that mounts when installing and fixing, with glue magnet steel and rotor core burst are mounted.After adopting this process to install, the defective of location deviation, the whole dynamic balance performance difference of rotor.Vibration and noise for motor rotation bring hidden danger.In order to eliminate rotor dynamic balancing, have to increase the dynamically balanced operation of corresponding calibration correction, increased corresponding manufacturing cost.
Summary of the invention:
The purpose of this utility model will overcome above-mentioned deficiency of the prior art exactly, and a kind of fixed structure of magnet steel is provided, and it can overcome with upper magnetic steel well when installing and fixing, and adopts the existing defective of mode that mounts.
The purpose of this utility model is to realize like this; a kind of fixed structure of magnet steel is by rotating shaft; rotor core; the magnetic loop iron core; magnet steel; engineering plastics are formed; it is characterized in that: rotating shaft and rotor core riveted joint; rotor core surrounded magnetic loop iron core; the magnetic loop iron core is outside equipped with the magnet steel groove; magnet steel attaches its outside; the plastics inserts is embedded between adjacent two magnet steel, and described engineering plastics are filled in rotor core and magnetic loop; between the slit between magnetic loop and sheet magnet steel, the formed thickness difference of magnet steel cylindrical convexity space; injection mo(u)lding securely is encapsulated in the rotor core periphery for the protection muscle with magnet steel.
The utility model uses through reality, and the mechanical strength of magnet steel is reliable, and magnetic property can improve more than 30% than common rotor, is well positioned to meet instructions for use after high low temperature reliability test, and this product has good use value and economic benefit.
