ELECTRIC MOTOR STATOR STRUCTURE AND POURING AND SEALING METHOD THEREFOR

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 adhesive being required for adhesive 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 an adhesive layer; the adhesive layer is formed by solidifying a liquid adhesive; the adhesive comprises a binding agent and heat-conducting insulating powder; and the particle size of the large-particle-size solid particles is greater 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 adhesive, such that the amount of the adhesive can be reduced, the solid large-particle-size solid particles are lower in cost than the adhesive and better than the adhesive in terms of heat conduction and insulation performance, and the toughness of the adhesive can be improved by adding the large-particle-size solid particles. The present application simultaneously achieves the effects of reducing the cost, improving the toughness of the adhesive and improving the heat conduction effect.
