Title:
ELECTRIC MOTOR STATOR STRUCTURE AND POURING AND SEALING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/143030
Kind Code:
A1
Abstract:
Disclosed is an electric motor stator structure, belonging to the technical field of electrical manufacturing. The electric motor stator structure solves the problems in the prior art of a large amount of glue being required for glue pouring of electrical elements and high cost. According to the electric motor stator structure, large-particle-size solid particles are arranged in large-size gaps between a shell, an iron core and/or a winding; small-size gaps between the shell, the iron core, the winding and/or the large-particle-size solid particles are filled with a colloid layer; the colloid layer is formed by solidifying a 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 electric motor stator structure, the solid large-particle-size solid particles are arranged in the colloid, such that the amount of the colloid can be reduced, the solid large-particle-size solid particles are lower in cost than the colloid and better than the colloid in terms of heat conduction and insulation performance, and the toughness of the colloid can be improved by adding the large-particle-size solid particles. The present invention simultaneously achieves the effects of reducing the cost, improving the toughness of the colloid and improving the heat conduction effect.
