Abstract
The present utility model discloses a series excitation type motor stator punching sheet structure. The structure comprises a punching sheet body which is provided with installing holes, a plurality of coiling grooves are uniformly arranged on the punching sheet body, the bottom part of each coiling groove is a square structure, the height of a stator yoke part of each coiling groove is not lower than 3.5mm, and the height of other parts is the same as that of the groove. Compared with the prior art, in the serial excitation type motor stator punching sheet structure, the shallow groove type round bottom part structure of the original stator is changed into a deep groove type square bottom part structure, according to the motor magnetic property design requirement, without changing the stator yoke part and the pole body magnetic density, insulation paper can be fixed and windings can be arranged inside the grooves when inserting winding of an automatic winding machine is carried out, the electromagnetic performance of the motor is not changed, automatic reeling of the stator coil windings of the serial excitation type motor can be realized, and convenient conditions can be provided for automatic reeling production of the stator.
Description
Technical field
The utility model relates to a kind of series excitation type motor stator, relates in particular to a kind ofly to roll off the production line and the stator laminating structure that designs for ease of the automation of series excitation type motor stator.
Background technology
The series excitation type motor is a kind of motor that a kind of stator and armature all have embedded coil windings; And embedded coil windings is to be accomplished by automation or semi-automatic plant equipment basically on the armature, and the embedded coil windings on the stator (stator punching external diameter≤Φ 65mm) generally is to turn to artificial again coil is embedded in the stator behind the coil earlier.
In order to enhance productivity, reduce labour intensity, stator coil is also want in automation once property completion on coil inserting apparatus.Stator coil wants to accomplish with mechanized equipment, and be bound to cutting in advance and forming slot liner paper are put into stator slot then, refill on automation equipment and roll off the production line.But owing to consider that the people artificially embeds again during the design of the stator punching of series excitation type motor after turning to coil, so the design of the flute profile of the both sides of punching is rounded bottom and trench bottom is more shallow.This punching coiling on the automation coil winding machine; Two unfavorable factors are arranged, the one, after putting into stator slot, cutting and forming slot liner paper is difficult to fix, because the trench bottom that rolls off the production line is a rounded bottom and more shallow; Can't freely fixedly cause skidding off easily: the 2nd, because the place's slot part that rolls off the production line is more shallow; Formed groove area is less, and the stator winding copper factor is higher, also causes winding to skid off easily in the stator slot and cause can't the automation coiling.
The utility model content
The purpose of the utility model is to provide a kind of series excitation type motor stator punching structure; It neither changes the electromagnetic performance of motor; The stator coil winding automation that can realize the series excitation type motor again is around embedding, solved effectively that the punching of series excitation type motor stator exists winding to skid off the problem of stator slot easily when the automatic winding coil in the prior art.
The purpose of the utility model is to realize through following technical scheme:
A kind of series excitation type motor stator punching structure; It comprises the punching body, offers installing hole on the said punching body, and is uniformly distributed with on the said punching body and is provided with several winding slots; Wherein, The bottom of said winding slot is a square structure, and the stator yoke portion of said winding slot highly is not less than 3.5mm, and all the other are groove depth.
Especially, be uniformly distributed with on the said punching body and be provided with four winding slots.
Especially, said punching body around offer a plurality of welding notches.
The beneficial effect of the utility model does; Said series excitation type motor stator punching structure compared with prior art mainly is that the round polycrystalline substance of former stator shallow-slot type is changed over deep slot type plinth structure; According to the designing requirement of motor magnetic property; Do not changing under the close prerequisite of stator yoke portion and pole body magnetic, considering emphatically to be convenient to automatic coil winding machine and carry out the fixing and winding of insulating paper when rule and all fall in the groove, neither changing the electromagnetic performance of motor; The stator coil winding automation that can realize the series excitation type motor again is around embedding, for the stator automation around the rule production condition of providing convenience.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the utility model series excitation type motor stator punching structure.
Among the figure:
1, punching body; 2, installing hole; 3, winding slot; 4, welding groove.
Embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the utility model series excitation type motor stator punching structure.
In the present embodiment, a kind of series excitation type motor stator punching structure comprises punching body 1, and correspondence offers installing hole 2 on the dual-side of said punching body 1; And be uniformly distributed with on the said punching body 1 and be provided with four winding slots 4; The bottom of said winding slot 4 is a square structure, and the stator yoke portion of said winding slot 4 highly is not less than 3.5mm, and all the other are groove depth; In addition, punching body 1 around offer a plurality of welding notches 4.
Said series excitation type motor stator punching structure applications is on stator outer diameter φ 63 series excitation type universal motors; The structure of this stator punching mainly is that the round polycrystalline substance of former stator shallow-slot type is changed over deep slot type plinth structure; According to the designing requirement of motor magnetic property; Do not changing under the close prerequisite of stator yoke portion and pole body magnetic, considering emphatically to be convenient to automatic coil winding machine and carry out the fixing and winding of insulating paper when rule and all fall in the groove.At first; We suitably align stator yoke portion magnetic is close, stator are laid the slot part at stator winding place and are deepened, and enlarge the flute profile size; Suitably reduce the size of yoke portion; But be no more than its close maximum of yoke portion magnetic that allows, and suitably align the electromagnetic parameter of electric machine rotor, reach comparatively ideal result.Because the reasonable levelling to stator laminating structure makes stator lay a kind of shape that the stator winding place becomes has multiple corner angle, so; The stator slot insulating paper also can be according to becoming the multiple edge angular shape according to the true form one-tenth at stator winding installation place with regard to root; This shape just with freely the fixing of stator slot insulating paper, no longer skids off it; And owing to deepened trench bottom; Also just strengthened the actual groove area of laying winding, winding can be fallen in the stator slot fully, for the stator automation around the rule production condition of providing convenience.
