Rotor core (magnetic core) plays the important and pivotal role inside whole motor, and it is used for increasing the magnetic flux of inductance coil, has realized the maximum conversion of electromagnetic power.Widely, stepping motor, AC/DC motor, reducing motor, external rotor electric machine, motor with cup rotor, synchronous asynchronous motor etc. has and utilizes more widely its range of application.For finished product motor, the effect that motor iron core plays inside motor accessory is more crucial.Want to allow the overall performance of a motor be improved, just need the performance promoting motor iron core.Usual this performance can adopt the material improving core stamping, adjusts the permeability of its material, and the mode such as size of iron loss controlled well solves.A good motor iron core needs, by the metal stamping die of precision, to adopt the techniques such as automatic riveting, then utilize the punching press of high precision punch table out.The benefit done like this is, farthest can ensure the integrity degree of the plane of its product, farthest ensure its Product Precision.Visible, the finished product motor that will ensure at present, requires all higher to the technology and equipment of its whole manufacture, so not only cause production cost high, and good ratio defective product is low, most of rotor core still easily occurs that vibration amplitude is large, the defects such as balance quality is not ideal enough.
Although as Chinese patent literature discloses a kind of rotor core structure [patent No.: 200920045258.8] of motor, it comprises in squirrel cage induction motor, can reduce motor electromagnetic noise.It mainly comprises first paragraph rotor core and second segment rotor core, and feature is: described first paragraph rotor core and second segment rotor core adopt short-circuited conducting sleeve to be connected.The utility model is simple, compact and reasonable for structure, and action effect is obvious; When not change structure material, under guarantee motor Energetic characteristic acceptance condition, adopt and be provided with short-circuited conducting sleeve on rotor core; When motor starting, two sections of rotor cores direction is due on the contrary, and the harmonic wave that the electromagnetic noise produced produces is cancelled out each other, and slackens electromagnetic noise.Although it has simple, compact and reasonable for structure, action effect is obvious; When not change structure material, under guarantee motor Energetic characteristic acceptance condition, adopt and be provided with short-circuited conducting sleeve on rotor core; When motor starting, two sections of rotor cores direction is due to the series of advantages such as contrary; But it is due to the restriction of structure, 3 iron core group therefore still needing multiple mould to make in the process manufactured form a rotor core group by mutual stack combinations again, cause its production efficiency low, do not possess the market competitiveness.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, the rotor core that long service life, stability are high.
For achieving the above object, the utility model have employed following technical proposal: a kind of rotor core being convenient to manufacture, comprise the lamination that several are superimposed, described lamination is provided with several and is convenient to through rivet hole and louvre, described lamination uniform distribution is overlapped into three iron core group linked together, and is followed successively by the first iron core group, the second iron core group and the 3rd iron core group; It is characterized in that, each iron core group forms by several laminations, described each lamination is equipped with two groups of uniform rivet holes, often organizing rivet hole is 4, each lamination is provided with two keyways simultaneously, two keyways in a circumferential direction in 45 °-55 ° distributions, a rivet hole wherein in one group of rivet hole and one of them keyway in same radius, a rivet hole of other one group of rivet hole then with another one keyway in same radius.
Described lamination is provided with several louvres.
Described lamination is circumferentially provided with a balancing hole at louvre, rotor core can be made to assemble the amount of unbalance after joining and reduce.
In described two groups uniform rivet holes, the adjacent uniform rivet hole of each uniform rivet hole and other a group is 2 °-8 ° with the angle of straight line that is formed centrally in lamination respectively.
Compared with prior art, the utility model has the advantage of: the utility model has the advantage of: 3 iron core group that 1, the design of rivet hole and keyway can make a secondary Lamination mould make form a rotor core group by mutual stack combinations, reduction manufacturing man-hours, simplify manufacturing step, overall reduction manufacturing cost; 2, rivet hole and the design of keyway can run through with rivet after 3 rotor core groups can be made to superpose; 3, that motor can be made to run is more steady for the rotor core structure of syllogic, torque pulsation and motor noise less.4, balancing hole be arranged so that the amount of unbalance of rotor core group in assembling process significantly reduces, simplify the workload of dynamic balance calibration, reduce the manufacturing cost of motor.
