Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of Combined motor stator structure.
Background technology
Motor is comprised of stator and rotor two parts, and stator comprises stator yoke, magnetic block and the winding on the magnetic block, the stator yoke of common motor is the integration stamped cirque structure that is pressed into of electrical sheet, then magnetic block is fixed on the inner ring of stator yoke, the stator yoke that has and magnetic block are to be made into integration, then by interior spooling equipment coil on magnetic block, therefore the tailing of remaining electrical sheet much can't utilize behind the stator yoke sheet punching press of ordinary construction, cause very large waste, cause the cost of whole motor very high.
Chinese patent Granted publication number: CN201286037Y, August 5 2009 Granted publication day, a kind of brushless motor stator is disclosed, this stator includes a cylindrical shape yoke, inner surface along the cylindrical shape yoke is provided with a plurality of protuberances radially to yoke central authorities, be formed with the gear line section that expands to the protuberance both sides respectively in the end of protuberance, the inner surface of gear line section is formed with the rotor container cavity, tow sides at the cylindrical shape yoke are inserted with two insulation framework that shape is identical, insulation framework is provided with several winding sections, described winding section can combine with protuberance and be coated on the outer surface of protuberance, is wound with coil in the winding section.This stator is to adopt in advance the insulation framework of compression molding to be inserted in the stator slot, it is combined together with stator, and then wind the line in the winding section of insulation framework, and is time saving and energy saving, wear-resistant, and insulation effect passes by greatly to improve.Its weak point is that the columnar stator yoke of this kind motor stator is the integral type structure, i.e. integration stamped pressing formation, and remaining a large amount of tailing can't use after the punching press, causes very large waste, causes the cost of motor high.
The utility model content
The utility model is the integral type structure in order to overcome motor stator yoke of the prior art, remaining tailing much can't utilize the deficiency that causes motor cost very high, provide a kind of simple in structure easy to assembly, the tailing that stator yoke produces in the punching out process is few, thereby saves the Combined motor stator structure that lot of materials reduces whole motor cost.
To achieve these goals, the utility model adopts following technical scheme:
A kind of Combined motor stator structure, comprise stator yoke and the magnetic block that is connected with stator yoke, described magnetic block is provided with coil, described stator yoke is formed by stacking by some layers of annular stator yoke sheet, described annular stator yoke sheet comprises some stator yoke punchings, and described stator yoke punching joins end to end and is combined into annular stator yoke sheet.Annular stator yoke sheet is to be joined end to end by a plurality of stator yoke punchings to form, be made into integration with common motor annular stator yoke and compare, the leftover pieces or the tailing that produce after the knockdown stator yoke sheet punching press of this kind are few, save significantly material cost, thereby reduced the cost of whole motor.
As preferably, described stator yoke punching is one-body molded, it comprises that stator yoke punching body is connected the punching afterbody that punching head that end connects is connected with the stator yoke body other end with stator yoke punching body, described punching head and punching afterbody all be located at stator yoke punching body homonymy and with stator yoke body structure in an angle, described punching head is provided with the connection breach, and described punching afterbody is provided with the connection projection corresponding with connecting breach.The connection projection of stator yoke punching inserts the connection breach of another piece stator yoke punching, the annular stator yoke sheet that final a plurality of stator yoke punching joins end to end and connects into a sealing, a plurality of annular stator yoke sheets formation stator yoke that is superimposed together, whole assembling process is simple.
As preferably, the inboard middle part of described stator yoke punching body is provided with the dovetail slot, one end of described magnetic punching is provided with the dovetail inserted block corresponding with the dovetail slot, and described magnetic block is formed by stacking by some magnetic punchings, and the other end of magnetic punching is circular arc.Dovetail inserted block in the magnetic punching inserts in the dovetail slot of stator yoke punching body inboard, such structure and common magnetic block and stator yoke integral structure are relatively, common structure coil will adopt special interior spooling equipment on magnetic block, this kind equipment cost height, and winding efficiency is low; And this structure that magnetic block and stator yoke body separate only need to be enclosed within the coil that winds on the magnetic block, then magnetic block is snapped in to get final product on the stator yoke, no matter is that this kind mode is more much lower than common mode cost from spooling equipment or coil itself.
As preferably, the both sides of the arc end of described magnetic punching stretch out and form the arc pin.The arc pin has effectively increased on the one hand the inner area near end with rotor of magnetic block, so the magnetic action of magnetic block is better in the effect of rotor, on the other hand coil is played a position-limiting action, prevents coil landing from the magnetic block.
As preferably, described annular stator yoke sheet is joined end to end by four stator yoke punchings and forms, the outside of the junction of described stator yoke punching is circular-arc, it is fast to be inserted with four magnetic in four dovetail slots of described annular stator yoke inboard, and the fast polarity of every adjacent two magnetic is opposite in described four magnetic blocks.Four stator yoke punchings just consist of up and down four positions of stator yoke, the while correspondence is four magnetic blocks up and down, this kind combination, the flexibility of stator yoke punching is very little, the leftover pieces and the tailing that produce in the punching out process are less, if the quantity of stator yoke punching is too much, it is more reasonable that then assembling and punching out trouble very all, so four stator yoke punchings is combined into this structure of annular stator yoke sheet.
As preferably, described connection breach is tight fit with the cooperation that is connected projection, and described dovetail slot is tight fit with cooperating of dovetail inserted block.Tight fit prevents from organizing stator after turning each stator yoke punching and magnetic punching in installation process and drops, and tight fit is so that whole knockdown structure is compacter simultaneously, and overall performance is strong.
As preferably, the thickness of described stator yoke punching and magnetic punching equates that its thickness is between 0.3mm-0.7mm, and described stator yoke punching and magnetic punching are made by electrical sheet.
Therefore, the utlity model has simple in structure easy to assemblyly, the tailing that stator yoke produces in the punching out process is few, thereby saves the beneficial effect that lot of materials reduces whole motor cost.
