The invention discloses a core structure of a skew-pole rotor of a permanent magnet motor and a laminating method of the core structure. The core structure comprises a shaft and rotor cores, wherein the rotor cores are provided with a first locating hole, a second locating hole, a third locating hole and a fourth locating hole respectively. According to the laminating method, the first locating hole of the first rotor core, the second locating hole of the second rotor core, the third locating hole of the third rotor core and the fourth locating hole of the fourth rotor core are located at the same circumferential position through a locating pin, a spiral staggered structure is formed by magnetic steel bonding faces on the rotor cores, and then the skew pole effect of the rotor can be achieved. The core structure of the skew-pole rotor of the permanent magnet motor and the laminating method of the core structure have the advantages that eddy-current loss of the motor can be reduced by the adoption of the laminated structure of the rotor cores, magnetic leakage between adjacent pieces of magnetic steel can be reduced by the arrangement of magnetism isolation grooves, the performance of the motor is improved, the structure is simple, and the machining and manufacturing process is convenient to carry out.

Description

Magneto skewed pole rotor core structure and closed assembly method
Technical field
The present invention relates to a kind of rotor structure of motor, relate in particular to a kind of skewed pole rotor core structure of magneto.
Background technology
Conventionally, rotor comprises iron core and axle, and the rotor of magneto also contains magnet steel, different motors can be because its magnetic circuit requires different, the structure of rotor also can be different, paste the rotor of magnet steel for oblique extremely surface, the structure of its iron core adopts integral type mild steel entirety car system to form often, before stickup magnet steel, need in advance at rotor core Surface Machining location notch or positioning rib, the processing that forms helical angle location notch with rotor axis direction is very complicated, cannot carry out with common process equipment, and also need to carry out with machining center with the processing of rotor axis direction formation helical angle positioning rib, this is not only time-consuming, increase processing cost, simultaneously also because rotor core is to be formed by overall steel part car system, in the time that motor moves, eddy current loss also can increase, reduce the power output of motor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of magneto skewed pole rotor core structure and closed assembly method.
The present invention solves the problems of the technologies described above adopted technical scheme: magneto skewed pole rotor core structure and closed assembly method, comprise axle, rotor core, the diameter of axle of described axle is loaded in the iron core endoporus of rotor core, described rotor core is provided with the first location hole, the second location hole, the 3rd location hole and the 4th location hole, described closed assembly method is the first location hole to the first rotor iron core with an alignment pin, the second location hole of the second rotor core, the 3rd location hole of third trochanter iron core and the 4th location hole fixation of fourth trochanter iron core are on same circumferential position, magnet steel sticking veneer on rotor core forms spiral helicine dislocation, reach the effect of skewed-rotor.
Described rotor core also comprises iron core endoporus, magnet steel confined planes, magnet steel sticking veneer and every magnetic groove.
Between the first location hole center of circle of described rotor core and the second location hole center of circle, between the second location hole center of circle and the 3rd location hole center of circle, equate in the angle of rotor core circle centre position between the 3rd location hole center of circle and the 4th location hole center of circle, the size of angle becomes to increase progressively relation with the gradient of skewed-rotor.
The described diameter of axle and iron core endoporus adopt interference fit.
The guide end of described axle and iron core endoporus adopt matched in clearance.
Compared with prior art, advantage of the present invention is that iron core adopts the structure of lamination can reduce the eddy current loss of motor, every the leakage field reducing between adjacent magnet steel that arranges of magnetic groove, improve the performance of motor, the mode that rotor core adopts punching to laminate, the punching of punching has advantages of that efficiency is high, the oblique utmost point of rotor directly forms while being press-fited by rotor core, greatly raise labour productivity, this rotor has simple in structure, and process for machining and manufacturing is feature easily.
