1. A motor cooling system for cooling a motor stator, comprising:
an insulated cooling pipeline;
wherein the insulated cooling pipeline is mounted in a stator housing, and a top surface of the insulated cooling pipeline is lower than or flush with a top surface of a stator iron core, a bottom surface of the insulated cooling pipeline is in contact with a coil of the motor stator for cooling the coil;
wherein the top surface of the stator iron core is arranged opposite to a rotor, so that a magnetic field generated by the coil interacts with a permanent magnet of the rotor.
