Abstract: A motor cooling system, a motor stator and a disc motor. The motor cooling system comprises an insulated cooling pipeline (2); the insulated cooling pipeline is mounted on a stator housing, the top surface of the insulated cooling pipeline is lower than or flush with the top surface of a stator iron core, and the bottom surface of the insulated cooling pipeline touches a coil of the motor stator for use in cooling the coil; the top surface of the stator iron core is configured to being arranged relative to a rotor, so that a magnetic field generated by the coil can interact with a rotor permanent magnet. Since the outer bottom surface of the insulated cooling pipeline touches the coil of the motor stator, a liquid coolant in the insulated cooling pipeline can cool the coil by means of heat conduction.

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 heart-conducting insulating powder.

Abstract: A motor cooling system, a motor stator and a disc motor. The motor cooling system comprises an insulated cooling pipeline (2); the insulated cooling pipeline (2) is mounted on a stator housing (3), the top surface of the insulated cooling pipeline (2) is lower than or flush with the top surface of a stator iron core (4), and the bottom surface of the insulated cooling pipeline (2) touches a coil (5) of the motor stator for use in cooling the coil (5); the top surface of the stator iron core (4) is used for being arranged relative to a rotor, so that a magnetic field generated by the coil (5) can interact with a rotor permanent magnet. Since the outer bottom surface of the insulated cooling pipeline (2) touches the coil (5) of the motor stator, a cooling liquid in the insulated cooling pipeline (2) can cool the coil (5) by means of heat conduction, thus preventing the motor from burning out due to the temperature of the motor increasing.
