Abstract
The utility model discloses a V-shaped servo motor rotor punching sheet. The V-shaped servo motor rotor punching sheet is provided with eight pairs of V-shaped magnetic steel grooves, six abnormity weight reduction holes, two square positioning holes, ten rivet holes and ten rivet emptiness avoiding holes. The rivet holes and the rivet emptiness avoiding holes are symmetrically distributed in a vertical alternative mode, when the front surface and the back surface of the punching sheet are laminated, the rivet holes in the front surface are in alignment with the rivet emptiness avoiding holes in the back surface, the magnetic steel grooves, the positioning holes and the weight reduction holes of the punching sheet are symmetrically distributed along the center of the rotor punching sheet, and motor rotor inertia is uniformly distributed along the center. The puinching sheet employs a V-shaped embedded structure, the length of a single sheet of magnetic steel is reduced, the saliency ratio of a motor is improved, and the V-shaped servo motor rotor punching sheet is provided with quite high weak magnetic performance and overload performance.
Description
Technical field
The utility model relates to a kind of embedded permanent magnet synchronous servo motor rotor structure, particularly a kind of " V " font permanent magnet synchronous servo motor rotor punching that can improve the weak magnetic property of motor and overload magnification.
Background technology
Existing embedded rotor structure mainly contains two kinds of built-in radial formula and built-in V word formulas, and wherein rotor punching outline is full circle.Above-mentioned built-in radial formula rotor punching magnet steel groove number is consistent with motor pole number quantity, when motor pole number is lower and power of motor is larger, for example when motor pole number is two utmost points, four utmost points, magnet steel length is longer, and magnet steel slenderness ratio is higher, magnet steel processing difficulties, the easily demagnetization of magnet steel middle part.Rotor punching mainly connects by flat key or rivet, wherein rivet connection possesses higher concentricity, when adopting rivet to connect, between each folded rotor punching, because of manufactured head end, can cause between every two-stage rotor iron core and produce gap, reduce effective length unshakable in one's determination, increased motor entire length.
Summary of the invention
The technical problem that the utility model equipment will solve is: in order to overcome the problem of above-mentioned existence, provide technique simple, can eliminate novel " V " font embedded rotor structure in every section of rotor core manufactured head gap.
The utility model equipment solves the technical scheme that its technical problem adopts: the punching of a kind of " V " font servo motor rotor comprises rotor punching body, and rotor punching material adopts cold-reduced silicon sheet 35DW300.On rotor punching body, have 8 pairs of equally distributed magnet steel grooves, magnet steel groove is positioned at rotor punching inside, be " V " font and distribute, by finite element analysis show when V-arrangement angle be 160 magnetic steel of motor utilance while spending and best performances.Described rotor punching outline, by 8 sections of eccentric arcs and 8 sections of rectilinear(-al)s, apart from regulating counter potential waveform, reduces high order harmonic component, the performance of lifting motor by eccentric adjustment arc eccentric.On described rotor punching body, along large small circumference, be evenly equipped with respectively rivet hole and 10 the rivet emptiness avoiding holes that diameter is 8.5mm that 10 diameters are 5.5mm.Rotor core adopts two-layer rivet to rivet, during rotor core assembling, successively every iron leg heart is replaced to positive and negative placement, the rotor core rivet of the second layer is kept away hole with the rotor core rivet of ground floor and is alignd, the rotor core rivet of the 3rd layer aligns with the rotor core rivet emptiness avoiding hole of two layers, the like the manufactured head gap between every section of rotor core can eliminate.On described rotor punching body, have 6 special-shaped lightening holes, can reduce the moment of inertia of motor, be conducive to rotor heat radiation.On punching body, have 2 square location holes, during rotor core assembling, utilize square location hole every section of rotor core magnet steel groove can be alignd.Described rotor punching has two kinds every magnetic bridge, be respectively homopolarity every magnetic bridge and heteropole every magnetic bridge, every magnetic bridge size impact interelectrode magnetic leakage, every the less leakage field of magnetic bridge size, more lesser trochanter punching intensity is lower.Described rotor punching body has 8 anti-slip tanks, and rotor core is that interference is connected with axle, and anti-slip tank two ends and shaft connection place can produce and scratch burr, can effectively increase frictional force unshakable in one's determination and axle.
The beneficial effects of the utility model are: technique is simple, can eliminate every section of rotor core manufactured head gap.
