Embodiment Construction

[0026] The specific content of the present invention will be described below in conjunction with the accompanying drawings.

[0027] see Figure 2-3 , a motor stator core structure, including a stator core 1 and a splicing block 2, the cross section of the stator core 1 is circular, the inner ring of the stator core 1 has a stator slot 11, and the stator slot 11 For embedding stator windings, the outer ring of the stator core 1 has cut surfaces 12 corresponding to the number of splicing blocks 2 , and the splicing blocks 2 are spliced ​​with the cut surfaces 12 .

[0028] The side of the splicing block 2 close to the cut surface 12 is adapted to the shape of the cut surface 12, and the shape of the outer ring after the splicing block 2 and the cut surface 12 are spliced ​​is adapted to the shape of the sleeved parts arranged outside the motor stator, Since most of the motors on the market are round and square in shape, the shape of the spliced ​​outer ring here is preferably ...

Abstract

The present invention relates to a motor structure, especially to a motor stator core structure. The motor stator core structure comprises a stator core, a stator slot is arranged at an inner ring ofthe stator core, and at least one section is arranged at the outer ring of the stator core; the motor stator core structure also comprises at least one splicing block being spliced with the at least one section, one surface, close to the section, of the at least one splicing block is completely fitted to the at least one section, and the at least one splicing block is made of materials with a thermal conductivity being larger than a thermal conductivity of iron. The problems are solved that a motor stator heat radiation structure is complex and heat radiation is not sufficient in the prior art.

Description

technical field [0001] The invention relates to a motor structure, in particular to a motor stator core structure. Background technique [0002] In the prior art, in order to improve the working efficiency of the motor, the power of the motor is often increased, and the high power of the motor will lead to a large heat generation. If the heat dissipation is not sufficient, it is easy to cause the internal temperature rise of the motor to be too high, which seriously affects the performance of the motor. and service life. Most motor stator structures in the prior art such as figure 1 As shown, the outer ring of the stator core 1 is approximately circular, and the inner ring is provided with a stator slot 11, and no cooling device is provided, so the heat cannot be dissipated in time, resulting in an excessively high internal temperature rise of the motor. The temperature rise of the iron core in contact with the winding (thermometer method) should not exceed the temperature...
