Embodiment 1

[0052] Such as Figure 1 to Figure 2 As shown, the present invention provides a motor stator structure, including a housing 1, an annular accommodation space is provided in the housing 1, and a stator core 2 and a winding wound on the stator core 2 are installed in the accommodation space. 3. The gap between the winding 3 and the housing 1 is filled with large-diameter solid particles 4, and the particle size of the large-diameter solid particles 4 is larger than the coil gap of the winding 3 and the stator core 2 and the winding 3 The size of the gap between them, the large-diameter solid particles 4 are spherical, and the outer diameter of the particles is 2mm. The spherical particles are convenient to fill in the gap and flow, and the filling density is uniform. Because the particle size of the large-diameter solid particles 4 is greater than the size of the gap between the coils of the winding 3 and the stator core 2 and the winding 3, when the large-diameter solid particl...

Embodiment 2

[0074] The structure and principle of this embodiment are basically the same as Embodiment 1, the difference is that the motor stator structure in this embodiment is applied to a double-rotor disc motor, such as image 3 Shown is a stator housing 1 of a double-rotor disc motor. The stator housing 1 includes an annular inner ring and an annular outer ring. The annular inner ring and the annular outer ring are installed coaxially to form a ring-shaped accommodation space that runs through both ends. The iron core 2 and the winding 3 are installed in the accommodating space, the accommodating space of the stator housing 1 forms a side-sealed cavity through a side sealing plate, and the large-diameter solid particles 4 are filled in the accommodating space. Between the casing 1, the iron core 2, and the winding 3, the colloid layer is formed by injecting the colloid into the accommodating space and submerging the large-diameter solid particles 4 and the winding 3 through a vacuum f...

Abstract

The invention relates to a motor stator structure, which belongs to the technical field of electrical manufacturing. The problems that in the prior art, the glue pouring amount of electrical elementsis large, and the cost is high are solved. According to the motor stator structure, large-particle-size solid particles are arranged in large-size gaps among a shell, an iron core and / or a winding; small-size gaps among the shell, the iron core, the winding and / or the large-particle-size solid particles are / is filled with a colloid layer, the colloid layer is formed by solidifying liquid colloid,the colloid comprises a binding agent and heat-conducting insulating powder, and the particle size of the large-particle-size solid particles is larger than that of the heat-conducting insulating powder. According to the motor stator structure, solid large-particle-size solid particles are arranged in the colloid, the use amount of colloid can be reduced, the cost of solid large-particle-size solid particles is lower than that of the colloid, the heat-conducting and insulating properties are higher than those of the colloid, the toughness of the colloid can be improved by adding the large-particle-size solid particles, and the effects of reducing the cost, improving the toughness of the colloid and improving the heat-conducting effect are achieved.

Description

technical field [0001] The invention belongs to the field of electric manufacturing, and relates to a motor stator structure, in particular to a colloid-filled motor stator structure and a potting method thereof. Background technique [0002] With the development of the new energy market, the requirements for new energy power systems are getting higher and higher, among which the miniaturization and weight reduction of high-power motors play an important role. The miniaturization of the motor means the increase of the power density, and the calorific value per unit volume is also higher and higher, which puts forward higher requirements on the heat dissipation system of the motor. The structure of existing motor products generally includes a rotor, a stator and a housing. More commonly, the fixed installation of the stator and the housing constitutes a part of the motor. Wherein the casing is provided with the mounting position of the iron core, the iron core is fixedly ins...
