Abstract
The utility model provides a novel motor stator core, which comprises a plurality of tooth pole units and connecting pieces; wherein, punch holes are arranged on the outer circumference of each tooth pole unit; and the connecting pieces are cooperated with the punch holes to connect the tooth pole units together. The novel motor stator core, which has the advantages of simple assembly method and low production cost, realizes the miniaturization and high efficiency of a motor.
Description
[technical field]
The utility model relates to a kind of electric machine structure, refers in particular to the core construction of the piecemeal assembling of motor stator.
[background technology]
Under the overall background of pursuing the high-efficient energy-saving environment friendly motor, engineers and technicians not only set about from aspects such as design of electrical motor, material selections, also need to excavate, overcome conventional motors structural manufacturing process difficult point, find not only economy but also can improve the method for motor performance from process aspect.
Conventional stator core is subjected to width of rebate and rule device-restrictive, and the stator slot area can not make full use of, and copper factor is lower, and this has directly influenced motor miniaturization and high efficiency.And traditional stator core is generally assembled by the mode of welding, not only operational sequence is loaded down with trivial details, and, also can pollute the surface of stator core when particularly adopting the mode of welding to assemble owing to consuming scolding tin and the investment weld mold improves cost.
Therefore, provide that a kind of assemble method is simple, production cost is low, can not pollute the reality on stator core surface for necessary.
[summary of the invention]
The purpose of this utility model is to provide that a kind of assemble method is simple, production cost is low, the New-type electric machine stator core of miniaturization, high efficiency.
For realizing the utility model purpose, provide following technical scheme:
A kind of New-type electric machine stator core that the utility model provides, it comprises a plurality of tooth pole units and connecting piece, the outer circumference portion of this tooth pole unit is provided with perforation, this connecting piece and this perforation each tooth pole unit that is connected.
As embodiment, the outer circumference portion two ends of this tooth pole unit misplace respectively and are provided with jut and recess, the jut of adjacent two tooth pole units and recess can be chimeric mutually, this jut is provided with perforation, this connecting piece passes the perforation on the jut of adjacent two tooth pole units, two juts are connected in series, to connect these adjacent two tooth pole units.As preferred embodiment, but the jut of adjacent two tooth pole units and recess fluid-tight engagement and outer surface smoother are joined, this connecting piece matches with perforation on the tooth pole unit jut, can make adjacent two tooth pole units link together and can freely rotate around connecting piece.This connecting piece can adopt screw or rivet or other rigid materials to be riveted.
The structure of this New-type electric machine stator core can improve the groove area availability greatly, and copper factor can reach more than 93%, and under same power condition, littler by 30% than conventional stator core motor volume.
The contrast prior art the utlity model has following advantage:
The utility model electric machine stator iron adopts the piecemeal chain structure, connect each tooth pole unit by connecting piece, can improve the groove area availability greatly, and under same power condition, littler than conventional stator core motor volume, its assemble method is simple, production cost is low, can realize motor miniaturization, high efficiency.

Fig. 3 is two tooth pole unit connection diagrams of the utility model embodiment.
[embodiment]
The utility model electric machine stator iron comprises a plurality of tooth pole units 1 and connecting piece, and the outer circumference portion of this tooth pole unit is provided with perforation, this connecting piece and this perforation each tooth pole unit 1 that is connected.
See also Fig. 1～3, the diagram of the utility model embodiment, the outer circumference portion two ends of this tooth pole unit 1 misplace respectively and are provided with jut 12 and recess (not indicating), as shown in Figure 2, the setting of staggering of the jut 12 on this tooth pole unit 1 left side and the jut 12 on the right, therefore two tooth pole units 1 can closely be inlayed joint together.This jut 12 is provided with perforation 13, and this connecting piece 2 passes the perforation 13 on the jut 12 of adjacent two tooth pole units 1, and two juts 12 are connected in series, and connects this adjacent two tooth pole units 1, and can freely rotate around connecting piece 2.These connecting piece 2 employing screws or rivet or latch or other rigid materials are riveted.
The structure of this New-type electric machine stator core can improve the groove area availability greatly, and copper factor can reach more than 93%, and under same power condition, littler by 30% than conventional stator core motor volume.
The above only is preferred embodiment of the present utility model, and protection range of the present utility model is not limited thereto, and anyly all belongs within the utility model protection range based on the equivalent transformation on the technical solutions of the utility model.
