The utility model relates to a motor field provides a cooling casing, motor and electric vehicle of motor, its, the cooling casing forms to the tubulose, be formed with along a plurality of annular channels of axial interval arrangement in the pipe wall of cooling casing, and be formed with along the axial extension in the pipe wall and feed through a plurality ofly the water supply runner and the return water runner of annular channel, and the water supply runner with the return water runner is with every two arc runner are split into to the annular channel. The cooling casing of motor make coolant only pass through one of them arc runner, can follow the water supply runner and reach the return water runner, arc runner's route is shorter relatively, the pressure differential of coolant in arc runner is less, temperature gradient is less, it is more even to dispel the heat. 本实用新型涉及电机领域，提供种电机的冷却壳体、电机及电动车辆，其，所述冷却壳体形成为管状，所述冷却壳体的管壁中形成有沿轴向间隔排列的多个环形流道，并且所述管壁中形成有沿轴向延伸并连通多个所述环形流道的供水流道和回水流道，并且所述供水流道和所述回水流道将每个所述环形流道分割为
