Abstract
The utility model relates to a slot-wedge-connected iron core which includes an iron core. The slot-wedge-connected iron core is characterized in that the iron core is composed of two semicircular rings which are centrosymmetric; the two semicircular rings are connected with each other via dovetail grooves. Because the two semicircular rings are centrosymmetric, the iron core has the excellent circular degree. The two semicircular rings are fixedly connected together effectively via the dovetail grooves. In order to improve the production efficiency, one axial end face of the semicircular ring is provided with the dovetail groove, and the other axial end face is provided with a dovetail groove key. The two semicircular rings are same in terms of shape, so the die producing cost is reduced. The slot-wedge-connected iron core is reasonable in structural design, through the centrosymmetric design, the integrated sealed circular ring iron core is realized, the intervals among coiling grooves are even, the last product magnetic field can be evenly distributed in the magnetic field, and the working efficiency of a motor is improved.
Description
Technical field
The utility model relates to the motor device field, especially a kind of stator core.
Background technology
Motor mainly is made of stator and rotor, and stator core is generally the closed circle structure, to form closed magnetic field.But owing to need coiling on the stator core, thus stator core generally by the forming of two semicircular ring, the iron core of semicircular ring behind complete coil again fixed combination form complete iron core together.But because the connected mode of two semicircular ring iron cores of the prior art is comparatively simple, so that coil can't cover two junctions between the semicircular ring iron core, cause the finished product external diameter round, coil and core field lose the defectives such as large.Can only pass through to increase number of turns in order to remedy these defectives, thereby it is more to cause copper cash to expose, and has affected fail safe, also so that waste of material.
The utility model content
The purpose of this utility model is to provide a kind of full symmetric for the deficiency that solves above-mentioned technology, and coiling rear magnetic field loss is little, the slot wedge disjunctor iron core that magnetic field is effective.
In order to achieve the above object, the slot wedge disjunctor iron core that the utility model is designed comprises iron core, it is characterized in that iron core is comprised of two centrosymmetric semicircular ring, and two semicircular ring connect by dovetail groove.Because Central Symmetry so that iron core reaches complete circular arc degree, and can be fixed together two semicircular ring effectively by dovetail groove.
For production efficiency is provided, an axial end on the described semicircular ring is provided with dovetail groove, and another axial end is provided with the dovetail sunk key.Then two semicircular ring are the living product of profile, have reduced the die sinking cost.
The resulting slot wedge disjunctor of the utility model iron core, reasonable in design designs by Central Symmetry, formed complete closed circle iron core, and so that the spacing of winding slot is consistent, so that final products magnetic field can be evenly distributed in the magnetic field, provide the operating efficiency of motor.Because the profile of two semicircular ring is living product, reduce the production cost of product in addition, be conducive to a large amount of productions.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the slot wedge disjunctor iron core that present embodiment is described comprises iron core 1, and iron core 1 is comprised of two centrosymmetric semicircular ring 2, and two semicircular ring 2 connect by dovetail groove 3.An axial end on the described semicircular ring 2 is provided with dovetail groove 3, and another axial end is provided with dovetail sunk key 4.
Claims (2)
1. a slot wedge disjunctor iron core comprises iron core, it is characterized in that iron core is comprised of two centrosymmetric semicircular ring, and two semicircular ring connect by dovetail groove.
2. slot wedge disjunctor iron core according to claim 1 is characterized in that an axial end on the described semicircular ring is provided with dovetail groove, and another axial end is provided with the dovetail sunk key.
