Description
Technical field
The utility model is a kind of motor stator, belongs to machine field.
Background technology
In prior art, stator core in motor is generally the structure of similar hollow cylinder, within it sidewall is provided with the wrapping post extended internally, space between wrapping post is winding slot, and the production method of motor stator first manufactures strip, side is the stator piece of wrapping post, bend to cylindric again, in order to bending convenience, a small gap of stepping down is offered in the centre on the base of winding slot, due to the restriction of processing method and the consideration of cost, the size of this small gap of stepping down generally is greater than in reality the bit space that allows bending needs, the bottom of the winding slot of the motor stator after machining is made still to leave this tiny breach, this will form corner angle, this will cause the diffusion of the magnetic line of force, thus cause the decrease in efficiency of motor, simultaneously due to brake forming, certainly will be from beginning to end, this junction not only forms corner angle, and also can form certain magnetic pole, the direct work affecting motor, and it is high that modern servo motor has control precision, the feature of stabilization of speed, when stator one has control voltage, rotor rotates immediately, so in the process of motor production, also higher to each hardware requirement of composition motor, in process of production, the required precision of the external diameter of stator and the internal diameter of casing is higher, the corresponding raising of precision of the two tolerance fit, if the external diameter of stator is bigger than normal, harder in assembling process, be easy to cause stator fin, if stator outer diameter is less than normal, fixing requirement is not reached after assembling, affect the performance of motor, so easily make troubles to production, affect the quality of production efficiency and motor.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of motor stator, protruding and groove is interlocked, and is difficult to come off and loosen, and improves the efficiency of splicing, ensure that the technological requirement of the stator after having spliced, the structural design of division core makes winding around the bottom to division core, can be covered with whole division core, improve copper factor, the distribution making the magnetic line of force more evenly rationally, improves the efficiency of motor.
To achieve these goals, the utility model realizes by the following technical solutions: described stator core is connected by multiple division core, described stator core is hollow structure, and stator core inner edge is provided with the wrapping post extended internally, and forms division core between wrapping post;
The bottom surface of division core is made up of two inclined planes, two inclined planes are connected and form obtuse angle, and the side of the division core of two inclined plane self intersections each with it is formed rectangular-shaped, form coil perforation between the described two division cores connected, each division core is respectively arranged with projection and groove for the two ends of splicing.
Further, described wrapping post end is provided with overhead structure.
Further, the shape of described projection and groove, size are all identical.
Further, the upper surface of described projection and the length of bottom are than being 1.5:1.
Further, described division core adopts snap fit to join end to end.
The beneficial effects of the utility model: the utility model is when splicing, protruding and groove is interlocked, be difficult to come off and loosen, improve the efficiency of splicing, ensure that the technological requirement of the stator after splice, the structural design of division core makes winding can around to dividing the bottom of core, be covered with whole division core, improve copper factor, the distribution making the magnetic line of force more evenly rationally, improves the efficiency of motor.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of division core of the present utility model;
In figure: 1-inclined plane, 2-side, 3-divide core, 4-overhead structure, 5-division core, 6-fillet, 7-groove, 8-projection, 9-fluting.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of technical scheme: a kind of motor stator, comprise stator core, it is characterized in that: described stator core is connected by multiple division core, described stator core is hollow structure, stator core inner edge is provided with the wrapping post extended internally, division core is formed between wrapping post, the bottom surface of division core is made up of two inclined planes, described two inclined planes are connected and form obtuse angle, and the side of the division core of two inclined plane self intersections each with it is formed rectangular-shaped, coil perforation is formed between the described two division cores connected, each division core is respectively arranged with projection and groove for the two ends of splicing.
Concrete occupation mode: the bottom surface of division core 3 is made up of two inclined planes, two inclined planes are connected and form obtuse angle, and the side of the division core 3 of two inclined plane self intersections each with it is formed rectangular-shaped, the structural design of this division core 3 makes winding can around the bottom to division core 3, be covered with whole division core 3, protruding 8 and the dual-side of groove 9 and its upper surface and bottom junctions be provided with fillet 6, when dividing core 3 and being spliced into stator, projection 8 and groove 7 are interlocked, the wearing and tearing between protruding 8 and groove 7 are reduced by fillet 6, when stator is squeezed, fillet 6 can play cushioning effect, stator is avoided to damage, simultaneously, when being installed in casing, need to extrude stator, stator outer diameter reduces, now, protruding 8 and groove 7 in the interphase interaction of fillet 6, create the resilience force expanded outwardly, when entering casing relevant position, during release extruding force, resilience force between fillet 6 is also discharged, impel stator resilience, be close to casing inner wall, projection 8 and groove 7 are positioned on same circular arc line, and direction is consistent, ensure that the stator precision be spliced to form is high, ensure that the pulsating field that stator can provide stable, the outer arc of division core 3 is provided with fluting 9, and fluting 9 is positioned on the center line of division core 3, improve the suppleness of division core 3, when dividing core 3 and being assembled into stator and being assembled in motor barrel shrond, shrinkage is better, be convenient to assembling, the included angle B that the dual-side of fluting 9 is formed is 20 °, improve the suppleness of fluting 9, thus improve the suppleness of division core 3.
More than show and describe general 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; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof
