Abstract

A motor stator core punching structure includes a yoke, a tooth, a wire embedding groove and a center hole, wherein the wire embedding groove and the center hole are connected, and characterized in that: the wire embedding groove has two or more different groove shapes, and each groove shape of the wire embedding groove adopts unequal tooth width, unequal groove depth, and unequal division measures, so that the division law changes symmetrically along the central axis of each pole phase group, and the change law between each pole phase group is the same. It can make full use of materials, make the layout more reasonable, make the design more optimized, reduce the cost of the product while meeting the requirements, and effectively improve the efficiency of the entire motor and save costs.

Description

A kind of motor stator core punching structure

Technical field:

The utility model relates to a kind of motor stator core punching structure.

Background technology:

At present, the stator laminating structure of motor, because its Structure Designing Problem causes consumptive material more, cost is higher, influences the operational efficiency of motor.

The utility model content:

In order to overcome the deficiencies in the prior art, the utility model provides the motor stator core punching that a kind of cost is low, efficient is high structure.

The utility model is achieved through the following technical solutions: a kind of motor stator core punching structure, comprise yoke portion, tooth portion, line embedding groove and centre bore, and line embedding groove and centre bore are connected, and it is characterized in that: line embedding groove has two kinds or two or more different flute profile.

Each flute profile of above-mentioned described line embedding groove adopts and does not wait the facewidth, equivalent gullet depth not, and the not measure of equal indicative changes the calibration rule to organize the axis mutually along every utmost point to be symmetrically distributed, and Changing Pattern was identical between each utmost point was organized mutually.

Above-mentioned described different flute profile areal extents: 35mm ²～145mm ²

The utility model compared with prior art, following advantage is arranged: the line embedding groove that 1) adopts two kinds or two kinds two kinds or two or more different flute profiles on the core stamping, can make full use of material more, layout is more reasonable, design is optimized more, under the situation of meeting the demands, can reduce the cost of product, can effectively improve whole efficiency of motor simultaneously, save cost.2) each flute profile of line embedding groove adopts and does not wait the facewidth, equivalent gullet depth not, and the not measure of equal indicative changes the calibration rule to organize the axis mutually along every utmost point to be symmetrically distributed, and Changing Pattern was identical between each utmost point was organized mutually.Further save material, reduce cost optimal design.3) above-mentioned described different flute profile area S scopes: 35mm ²～145mm ², optimal design.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

Example example 1: as shown in Figure 1, the utility model comprises yoke portion 1, tooth portion 2, line embedding groove 3 and centre bore 4, and line embedding groove 3 and centre bore 4 are connected, and line embedding groove 3 has two kinds or two or more different flute profile.Be divided into I shape line embedding groove and II shape line embedding groove among the figure, each flute profile of line embedding groove adopts and does not wait the facewidth, not equivalent gullet depth, the not measure of equal indicative, the calibration rule is changed along every utmost point organize the axis symmetrical distribution mutually, Changing Pattern was identical between each utmost point was organized mutually, described different flute profile areal extents: 35mm ²～145mm ²

Wherein the groove depth H1 of I shape line embedding groove is bigger than the groove depth H2 of II shape line embedding groove, and the facewidth L1 of adjacent two I shape line embedding grooves is greater than the facewidth L2 of adjacent two II shape line embedding grooves, and the circumference calibration of two I shape line embedding grooves is different with the circumference calibration of II shape line embedding groove.Among Fig. 1, adjacent two I shape line embedding grooves are organized mutually with adjacent two II shape line embedding grooves combination poling, a utmost point of corresponding stator, each utmost point are organized mutually along axis A-A and are symmetrically distributed, and Changing Pattern was identical between each utmost point was organized mutually.

Claims (3)
