Description

Stator punching, stator core, field frame assembly and motor

Technical field

The utility model relates to technical field of motors, total in particular to a kind of stator punching, stator core, stator At and motor.

Background technique

Currently, the stator of the two poles of the earth alternating current generator, generallys use two mutual split groups of stator core with single groove profile At.

But stator in this way must carry out coiling using moving station wire winding, it may be assumed that firstly the need of elder generation Half of stator core is clamped in the winding for completing main phase winding on the coil winding machine of winding main phase winding, it is fixed then to unload this one side of something Sub- iron core is displaced on the coil winding machine of another winding pair phase winding, then clamps one side of something stator core around secondary phase winding, thus Complete the coiling work of half of stator core；Then the coiling work of in addition half of stator core is completed using same winding mode Make；Finally two half of stator cores are stitched and fastened.Since the coiling of a stator core in winding process need to be in difference Station on complete, cause the production efficiency of stator assembly lower, also intangibly increase the workload of operating staff.

In addition, the stator core of single groove profile will lead to when having biggish difference for the umber of turn of main phase and secondary phase Main phase has biggish difference with secondary corresponding copper factor, and there is the hidden danger of biggish turn-to-turn pressure resistance.

Finally, for the lower working environment of temperature increase requirement, the electromagnetism fan-out capability of stator core cannot preferably be turned Change output；Furthermore under the conditions of, groove profile smaller for stator core size is lesser, single groove profile is unable to satisfy placement sleeve Requirement.

Utility model content

At least one in order to solve the above-mentioned technical problem, one of the utility model is designed to provide a kind of stator punching Piece.

Another of the utility model is designed to provide a kind of stator core including said stator punching.

Another of the utility model is designed to provide a kind of field frame assembly including said stator iron core.

The further object of the utility model is to provide a kind of motor including said stator assembly.

To achieve the goals above, the technical solution of the utility model first aspect provides a kind of stator punching, comprising: Yoke portion；With multiple teeth portion, it is connected with the inward flange of the yoke portion radially, and is set along the circumferential direction interval in the yoke portion It sets, multiple teeth portion match the multiple stator slot positions limited for the single winding of winding, and multiple institutes with the yoke portion Stator slot position is stated with a variety of groove profiles.

The stator punching that the technical solution of the utility model first aspect provides, yoke portion and multiple teeth portion match restriction Multiple stator slot positions out are superimposed by the stator punching and are formed for the single winding of winding (main phase winding or secondary phase winding) Stator core need to only can be completed on a coil winding machine in coiling coiling work, without unloading stator in winding process Then iron core pieces together the respective multiple stator cores for completing coiling work, to eliminate in the prior art Moving station wire winding improves the production efficiency of stator assembly, also reduces the workload of operating staff.Such as: for Two-phase motor is superimposed the stator core formed by this stator punching for four and pieces together；For three-phase alternating current Motor pieces together six stator cores by this stator punching depression formation.

Simultaneously as multiple stator slot positions have a variety of groove profiles, it can be according to the number of turns and pair phase winding of main phase winding The number of turns carrys out the specific winding position of reasonable Arrangement, to be substantially reduced the difference of main phase winding copper factor corresponding with secondary phase winding It is different, and then the hidden danger of turn-to-turn pressure resistance is significantly reduced, preferably matching adapts to this condition, and utilizes stator core in a higher degree Use material.
