Abstract

The utility model provides a silicon steel sheet rotor for an AC permanent magnet servo motor, comprising a rotary shaft, a rotor iron core arranged on the rotary shaft and magnetic bodies attached to the outside of the rotor iron core, wherein the rotor iron core is formed by stacking a plurality of punching sheets; the plurality of punching sheets are fixedly connected through rivets evenly arranged, and the stacking direction of the punching sheets is vertical to the magnetic flux direction of the magnetic bodies; the outer side of the whole rotor iron core is fixedly provided with magnetic shoe sleeves; the rotor iron core formed by stacking the plurality of punching sheets has the advantages of avoiding the generation of a plurality of vortex flows, reducing the heat generated by the rotor, protecting the rotor, particularly the magnetic bodies of the rotor, and prolonging the service life of the rotor.

Description

Alternating-current permanent-magnet servo motor silicon steel sheet rotor

Technical field

The utility model relates to a kind of rotor, especially relates to a kind of alternating-current permanent-magnet servo motor silicon steel sheet rotor.

Background technology

At present, the alternating-current permanent-magnet servo motor rotor that China produces mainly adopts solid shafting, for the alternating-current permanent-magnet servo motor rotor of large volume, adopt solid shafting that processing and production have been brought very big difficulty, also brought unnecessary potential safety hazard lifting is installed.In addition, general solid shafting in use can produce very big eddy current, thereby cause the loss of energy, energy use efficiency is low, and a large amount of heats that produce all bring very big loss to the various piece of rotor, special high temperature can make magnetic be more prone to come off for the magnetic that is bonded on the rotor core, thereby needs the new rotor of research and development can avoid above-mentioned defective as far as possible.

Summary of the invention

The utility model mainly is that to solve the eddy current that the existing in prior technology rotor produced big, energy loss is many, make the technical problem that comes off easily between magnetic and the rotor core, and provide a kind of eddy current amount that can reduce, reduce the motor power loss, prolong that motor useful life and assembling are simple, cost is low, alternating-current permanent-magnet servo motor silicon steel sheet rotor.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of alternating-current permanent-magnet servo motor silicon steel sheet rotor is provided, comprise rotating shaft, rotor core in the rotating shaft, the magnetic that the outer subsidy of rotor core is closed, its special feature is, described rotor core is overrided to form by some punchings, described punching is a silicon steel sheet, these some punchings are by evenly distributing, and the rivet that runs through punching is fixedly connected, the superimposed direction of punching is vertical with the direction of magnetic magnetic flux, is fastened with the magnetic shoe overcoat in the whole rotor core outside.Be laminated to certain altitude mutually by thin and many punchings; use riveted joint or fixedly punching of welding; rotor portion as motor; the punching of adopting is a permeability magnetic material; mainly select for use silicon steel sheet to make; described rivet plays the effect of fastening these some punchings; overcoat can be protected magnetic can not be subjected to action of centrifugal force in the rotor high-speed rotating process and outwards come off; the rotor core that uses this silicon steel sheet stack and form has the eddy current that is produced by magnetic flux on the minimizing rotor; reduce the caloric value of rotor; can arbitrarily carry out the stack of punching in addition, make rotor core have correctability, avoid the waste of iron core according to the length of rotor.

As preferably, 0.2 millimeter of the thickness of described punching---1 millimeter.Thin punching can reduce the generation of eddy current efficiently.

As preferably, described magnetic is the plurality of magnetic steel disc, and this magnetic links is bonded in the rotor core outside.

As preferably, the material of described magnetic shoe overcoat is non-magnetic conductive metal material, perhaps carbon fiber pipe, perhaps band, wire twister, perhaps engineering plastics, perhaps heatproof heat-shrinkable T bush.Non-magnetic conductive metal material, can make permanent magnet in the overcoat of this material, magnetic loss can not take place, prolong the useful life of magnetic, carbon fiber pipe then has very high intensity and toughness, under the impact of very big external force, can not break, and band, the wire twister can closely be wrapped in rotor exterior and can not cause magnet steel to come off, the heat-shrinkable T bush of engineering plastics and heatproof can shrink when being heated, can be wrapped in the outside of rotor closely, utilize the characteristic of the tensile strength of material self, offset magnetic material on the rotor in centrifugal force under the high rotating speed, prevent that magnetic material breaks away from rotor.

Therefore, the utlity model has rational in infrastructurely, manufacturing process is simple; cost is low; characteristics such as wide accommodation, laminating and the rotor core that forms has the generation of avoiding a large amount of eddy current of design especially by the multi-disc punching, the heat that has reduced rotor produces; protected rotor itself; especially magnetic has prolonged useful life of rotor, can arbitrarily carry out the stack of punching in addition according to the length of rotor; make rotor core have correctability, avoided the waste of iron core.

Accompanying drawing 1 is a kind of structure schematic diagram that punching of the present utility model laminates into rotor core;

Accompanying drawing 2 is a kind of structure schematic diagrames of the present utility model;

Accompanying drawing 3 is a kind of assembly structure schematic diagrames of the present utility model;

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment: the utility model is a kind of alternating-current permanent-magnet servo motor silicon steel sheet rotor, this rotor comprises rotating shaft, rotor core 1 in the rotating shaft, rotor core is outside paste and magnetic 2, wherein rotor core is overrided to form by some punchings 3, silicon steel sheet is selected in punching in the present embodiment for use, the superimposed direction of punching is parallel with the direction of magnetic magnetic flux, punching is fixedly connected by equally distributed rivet 4, rivet penetrates all punchings by the rivet hole in the punching 5, wherein the thickness of each punching is 0.5 millimeter, as shown in Figure 1.The magnetic that applying N and S are separated by outside the iron core that punching was overrided to form, in the rotor core outer end behind the applying magnetic fastening again on the magnetic shoe overcoat, overcoat 6 and back overcoat 7 were fixed from two ends respectively before the magnetic shoe overcoat was divided into, and the material of overcoat is selected body of stainless steel for use.

At first use the magnetic conduction silicon steel sheet material as rotor punching, by being laminated to certain altitude, right or use the riveted and fixed lamination, the lamination that is laminated to after the certain height and connects with rivet is as the rotor core module, then magnet steel is labelled to iron core module surface, as rotor module, the outer end puts the magnetic shoe overcoat again, at last rotor module and rotating shaft is assembled into the rotor of one as alternating-current permanent-magnet servo motor.
