PROBLEM TO BE SOLVED: To provide a stator of a direct-drive liquid cooling motor that can reduce an obstacle of heat conduction, improve the effect of the heat conduction, simplify elements, and be used to comply with water service cooling system of a conventional annular aluminum casing. SOLUTION: The stator of the direct-drive liquid cooling motor, which is assembled on a rotor shaft having magnets, includes an annular base, a silicon steel plate, at least one cooling metal pipe, and a coil. In this stator, a space for the rotation of the rotor shaft is opened in the center of the annular base. The silicon steel plate is positioned inside the annular base and some accommodation grooves are provided on its surface surrounding the rotor shaft. The cooling metal pipe is positioned inside the silicon steel plate in a crank shape and a cooling liquid is circulated in the pipe. The coil is wound on the silicon steel plate.
