The utility model discloses a permanent magnet direct drive electric roller structure of a cooling structure. Wherein the roller rotor penetrates through two ends of the central shaft, the stator is formed by superposing stator punching sheets and is fixed by a stator end plate, the stator is fixed on the outer diameter of the water jacket through a snap ring, the central shaft is connected with the water jacket through spoke plates in a welding manner, and the water jacket is equally divided into six small cooling cabins by the six spoke plates. A water inlet and a water outlet are formed in one end of the center shaft. And the water inlet pipe and the water outlet pipe are arranged in different cooling cabins. And a connecting hole for connecting the adjacent cooling cabins is formed above each center plate. And the water inlet pipe and the water outlet pipe are drilled in the central shaft and are connected with a cooling cabin. The cooling liquid enters one of the cooling cabins from the water inlet throu
