Abstract
The invention relates to a round laminated rotor structure for a salient pole synchronous motor. The structure comprises laminated iron core stampings, a damping rod and a pole coil, wherein the laminated iron core stampings are round stampings; a magnetic pole on the stampings is radial; a round damping hole for placing the damping rod is stamped on the magnetic pole; and the damping rod and the pole coil are respectively arranged in the damping hole and the pole body of the magnetic pole. The round laminated rotor structure for the salient pole synchronous motor has a simple structure and high reliability and fills a gap of a laminated rotor for a large-scale high-speed salient pole synchronous motor in domestic motor industry.
Description
Technical field
The present invention relates to the salient pole synchronous electric machine rotor, relate in particular to large high-speed salient pole synchronous electric machine rotor.
Background technology
It is 1000～1500rpm that present steel rolling high-speed rod engineering main transmission milling train is all selected rotating speed for use, even reaches the synchronous motor of 1800rpm.Because rotating speed is higher, it is not enough to be subject to the rotor pack magnetic pole strength, and the synchronous motor of solid magnetic pole has all been made by domestic electric machine factory, solves the problem of laminted pole insufficient strength with this.But the pole shoe of solid pole synchronous motor be with the bolt of some tight on solid magnetic pole, exist certain potential safety hazard and solid pole synchronous motor when the adapted voltage frequency converter, because harmonic content is big in the power supply, can produce big supplementary load loss on solid magnetic pole surface and make the pole shoe surface overheated even burn out the pole coil insulation, thereby cause serious burning machine accident.In addition because pole shoe surface temperature height, increase its tension stress greatly thereby also can generate heat the bolt of tight pole shoe, when pulling force that the centrifugal force of pole shoe can bear greater than bolt, bolt will be broken, thus the initiation serious accident.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, can satisfy various conversion power supply power supplys, be used in the high strength under the high speed operation mode, the stacked salient pole synchronous electric machine rotor structure of full circle of high reliability thereby provide a kind of.
Technical scheme of the present invention is as follows:
The stacked salient pole synchronous electric machine rotor structure of a kind of full circle, comprise the core stamping, damper rod and the pole coil that laminate, described core stamping is that yoke and magnetic pole are the rounding type punching of one, magnetic pole is distributed on the yoke radially, punching out damping hole on the pole shoe of magnetic pole, damper rod is placed in the described damping hole, and pole coil is nested on the magnetic pole pole body.
Useful technique effect of the present invention is:
The present invention is simple in structure, reliability is high, and action effect is obvious; Be adapted to various conversion power supply power supplys, can not cause big pole shoe surface supplementary load loss, the rotor strength height, thus filled up the blank of the stacked salient pole synchronous electric machine of domestic large high-speed.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes core stamping 1, damper rod 2 and the pole coil 3 that laminates.Core stamping 1 is that yoke 1a and magnetic pole 1b are the rounding type punching of one, and magnetic pole 1b is distributed on the yoke 1a radially, and the pole shoe 1c of magnetic pole 1b goes up punching out damping hole 4, and damper rod 2 is placed in the damping hole 4, and pole coil 3 is nested on the magnetic pole 1b pole body.With the damping ring (not shown) damper rod 2 short circuits are formed the absolute damping structure again, pole coil 3 connects by the interpolar line.
The operation principle explanation: rotor core of the present invention is overrided to form by the full circle punching of 1～3mm of some, owing to adopted laminated structure, the big eddy current loss (supplementary load loss) that can effectively reduce of bar to bar resistance reduces temperature rise, and improved the electromagnetism follow-up capability, improve the electromagnetic performance of motor greatly.The absolute damping winding is housed on the rotating pole-piece, and nested pole coil on the pole body when feeding DC power supply to pole coil, will produce a magnetic field synchronous with the stator rotating magnetic field, thereby make motor run on synchronous regime.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
