Description
Technical field
The utility model belongs to the synchronous motor technical field, is specifically related to the rotor punching structure with capability of fast response of servo permanent-magnetic synchronous motor rotor.
Background technology
Along with deepening continuously of the develop rapidly of high performance permanent magnetic materials technology, power electronic technology, microelectric technique and vector control theory, Theory of Automatic Control research, the permagnetic synchronous motor servo-control system has obtained develop rapidly.As the servo-control system performance element, permagnetic synchronous motor has overcome a series of restrictions that DC servo-motor mechanical switching device and brush bring, it is superior to have speed adjusting performance, simple in structure, reliable, and advantage such as volume is little, in light weight, efficient is high, power density is high, power factor is high, rotor moment of inertia is little, overload capacity is strong.More and more higher in high-performance, high-precision servo field to the requirement of the response speed of permagnetic synchronous motor.
As everyone knows, rotor magnetic circuit structural is the key technology place of permagnetic synchronous motor, the rotor magnetic circuit structural difference, and the runnability of motor, control system, manufacturing process and applicable situation are also inequality.The surperficial protruding-type rotor structure of the many employings of servo permanent-magnetic synchronous motor rotor.At this moment, permanent-magnetic synchronous motor rotor yoke portion magnetic is close often not to be very high, has very most of rotor yoke not to be fully utilized, and so not only can cause the increase of motor weight, can influence the dynamic responding speed of permagnetic synchronous motor simultaneously again.Therefore, suddenly wait to improve the rotor structure of permagnetic synchronous motor, at first should improve the rotor punching of motor, the rotor punching of existing servo permagnetic synchronous motor, as the patent No. is " AC servo motor rotor " patent of ZL200520077102.X, disclosed rotor punching is to offer equate with the number of poles of motor tri-angle-holed, the tri-angle-holed same circumference that is evenly distributed in silicon steel punching on each silicon steel punching.The major defect of this rotor punching is:
1, do not consider the segmented mode of rotor, can not more effectively satisfy dynamo seriesization;
2, on silicon steel punching, offer tri-angle-holedly, but because the restriction of mechanical strength, cause very near that the two triangle hole site can not lean on, can not reduce the rotor punching quality fully, thereby make motor can not obtain better moment of inertia.
3, limited to the close raising of rotor yoke magnetic.
Summary of the invention
The purpose of this utility model is the weak point at existing servo permanent-magnetic synchronous motor rotor punching, a kind of servo permanent-magnetic synchronous motor rotor punching is provided, have performances such as moment of inertia is little, rapid dynamic response speed, speed-regulating range width, be convenient to the characteristics such as producing in serial form of servo permagnetic synchronous motor simultaneously again.
The utility model realizes that the technical scheme of purpose is: a kind of servo permanent-magnetic synchronous motor rotor punching, center at rotor punching is provided with axis hole, on the surrounding edge of axis hole, offer a keyway, in order to be connected, it is characterized in that: on the rotor punching and be positioned on the same circumference in the axis hole outside and be evenly equipped with the erose repeated hole that goes that equates with motor pole number with axle.Go in the repeated hole described, rivet hole be set at the repeated hole outside top end that goes of symmetry, when described rotor punching laminates into rotor section by these rivet holes with integral body of the affixed one-tenth of rivet.The excircle of described rotor punching is provided with the location gear piece that equates with motor pole number, forms tooth after described rotor punching is laminated into rotor section, and rotor section is located permanent magnet by positioning tooth.Servo permanent-magnetic synchronous motor rotor punching once is stamped to form with silicon steel sheet.
The described erose base of repeated hole of going is the circular arc concentric with the axis hole of rotating shaft, arc radius is that 5～50mm both sides are that extended line is crossed center of circle straight line, angle α is 15 °～75 °, the upper edge of removing repeated hole is two inner concave curves that go repeated hole center line symmetry relatively, sweep is 5～300mm, and the center of circle of described inner concave curve and radius are determined according to the close size of the magnetic of rotor yoke, requirement of strength.The described center line of repeated hole that goes aligns with described two location gear piece center lines.Calculate and optimization such as vibrations calculatings draws removes repeated hole according to electromagnetism FEM (finite element) calculation, intensity, guarantee that not only perforate does not influence the electromagnetic performance of motor, the while also can not influence the mechanical performance of rotor.Describedly go the angle of spot hole outside the repeated hole derivet hole to be the chamfering that radius is 0.3～3mm.
After the utility model adopted technique scheme, main effect was:
1, owing to going repeated hole upper edge curve similar, little to the rotor yoke influence of magnetic field to magnetic line of force tendency, do not influence the motor electromagnetic performance.
2, go the existence of repeated hole the magnetic line of force to be led and effectively inhibition, thereby form symmetrical distribution magnetic field, improve electric efficiency.
3, go the existence of repeated hole to improve the heat-sinking capability of servo permanent-magnetic synchronous motor rotor.
4, going out to stamp out rivet hole near magnetic pole, because it just in time is in the magnet steel center, so offering of rivet hole do not influence the rotor Distribution of Magnetic Field, can reduce the welding and in of the influence of traditional handicrafts such as main magnetic circuit riveted joint to servo permanent-magnetic synchronous motor rotor magnetic field, simultaneously, be convenient to the blocking of servo permanent-magnetic synchronous motor rotor and the seriation of servo permagnetic synchronous motor.
5, considering the rotor punching mechanical strength, not influencing under the situation of motor-field distribution, alleviate servo permanent-magnetic synchronous motor rotor weight to greatest extent, reduced moment of inertia, improved servo permagnetic synchronous motor response speed.
6, rotor removes each rounding of angle of repeated hole, has improved the useful life of rotor stamping die greatly.
7, the existence of positioning tooth makes the bonding more convenient of magnet steel.
The utility model can be widely used in the series of servo permagnetic synchronous motor.
