Abstract
The utility model provides a novel solid salient pole synchronous motor rotor for solving the defect of disabled structure brought by the bigger centrifugal force generated when the rotor operates for a long time owing to the designing of the end of a solid salient pole synchronous motor rotor. The rotor comprises a plurality of rotor salient poles, two ends of the external surfaces of the salient poles of the rotor are provided with gaps along the radial edge of the rotor, circular arc end rings are embedded in the gaps, and one end ring extends outside the external surface of the salient pole of the rotor and is connected with the end ring of the adjacent salient pole of the rotor. The end rings of the utility model are fixed on the surface of the salient poles of the rotor in a heating jacket mode, the restriction between each part of the rotor is increased, which is beneficial to increase the stability of the integral structure of the rotor and the reliability, simultaneously the effect of eddy current is reduced, the starting torque is increased, and the starting property is more stable.
Description
Technical field
The utility model relates to solid salient pole synchronous electric machine technical field, specifically, relates to a kind of solid salient pole synchronous electric machine rotor.
Background technology
Along with deepening continuously of reform and opening-up, industries such as domestic metallurgy, chemical industry, papermaking have been introduced a considerable amount of large sized complete sets of equipments or emphasis equipment, and the drive motors of some of them equipment is exactly the solid rotor synchronous motor.Advantages such as because this motor has rotor mechanical reliability height, starting performance is good, and vibration and electromagnetic noise be lower during operation can't substitute at other type motor of some application.Yet, these motor overload operations for many years, the big centrifugal force that produces during rotor tip design long-play brings structural failure, both influenced normal production, cause great economic loss again, standby motor is sought to motor manufacturer one after another by each enterprise, and domestic manufacturer's seldom production the type motor. at present domestic all in the solid rotor synchronous motor overwhelming majority of usefulness from external introduction or directly supporting, price is very expensive, not only bring certain burden, and it is also very unfavorable that enterprise is reduced cost to national foreign exchange reserves.If the type motor can well be researched and developed manufacturing at home, its finished product is compared with external motor of the same type and will be had very big price advantage, and concerning the user who uses this motor, then provides reliable guidance more.As standby host and new necessary electromotor, the total demand space will be very huge.
The utility model content
The purpose of this utility model is to bring the deficiency of structural failure in order to solve the big centrifugal force that produces when solid salient pole synchronous electric machine rotor tip designs long-play, and a kind of new solid salient pole synchronous electric machine rotor is provided.
The technical problem that the utility model solved can realize by the following technical solutions:
A kind of solid salient pole synchronous electric machine rotor, comprise a plurality of rotor with salient pole, it is characterized in that: described rotor with salient pole outer surface two ends all have breach along the edge of rotor radial, embedding the end ring that has circular-arc end ring, described end ring to extend rotor with salient pole outer surface and adjacent rotor salient pole in the described breach joins.
In the utility model, the radius of curvature of described circular-arc end ring is less than the radius of curvature of rotor with salient pole outer surface, and end ring heating after heat cover embeds in the breach on rotor with salient pole surface.
Described rotor with salient pole surface offers a plurality of grooves along rotor axial, all is placed with sliver in the described groove, makes that the effective coverage owing to the rotor with salient pole surface increases under same revolutional slip, and its rotor impedance reduces, and exerts oneself thereby improve motor.
The utility model end ring is fixed on the rotor with salient pole surface in the mode of hot jacket, increased the constraint between each parts of rotor, helped strengthening integrally-built stability of rotor and reliability, the while has also reduced eddy current effect, increased starting torque, made starting performance more stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model one utmost point.
Fig. 3 is the structural representation after the utility model one utmost point removes end ring.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 1, Fig. 2, shown in Figure 3, solid salient pole synchronous electric machine rotor of the present utility model, comprise a plurality of rotor with salient pole 1, this is identical with existing solid salient pole synchronous electric machine rotor structure, solid field spider with 4 utmost points in the present embodiment is that example describes, be not to restriction of the present utility model, the basic structure of solid salient pole synchronous electric machine rotor is not inventive point of the present utility model, therefore is not repeated.
Rotor with salient pole 1 outer surface two ends all have breach 2 (side of far-end also is provided with breach) along the edge of rotor radial, embed in the breach 2 circular-arc end ring 3 is arranged, the radius of curvature of end ring 3 is less than the radius of curvature of rotor with salient pole 1 outer surface, end ring 3 heating after heat covers embed in the breach 2 on rotor with salient pole 1 surface, end ring 3 is made of metal usually, in the embedding breach 2 that end ring 3 cooling back deformation can be firm.The end ring that the end ring 3 of every utmost point extends rotor with salient pole 1 outer surface and adjacent rotor salient pole joins, and all end ring constitute a circulus, have increased the constraint between each parts of rotor, help strengthening integrally-built stability of rotor and reliability.
Rotor with salient pole 1 surface offers a plurality of grooves 4 along rotor axial, all is placed with sliver (not signal) in the groove 4, makes that the effective coverage owing to the rotor with salient pole surface increases under same revolutional slip, and its rotor impedance reduces, and exerts oneself thereby improve motor.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
