The utility model belongs to motor and generator field specifically provide a motor with direct -cooled structure. The utility model discloses the problem that current forced water cooling motor can not be be fully gone out the heat conduction in the motor aims at solving, the utility model discloses a motor with direct -cooled structure include encircle the stator and with the surface of the stator closely casing of laminating and the end cover of a tip sealing this casing, be provided with the inner ring component between end cover and the stator, make the end cover the casing the stator with the inner ring component forms toroidal cavity jointly to let in hydraulic oil, and be provided with inlet and liquid outlet on toroidal cavity. In hydraulic oil injects toroidal cavity from the inlet, with stator winding direct contact, the exchange heat of motor, again through the liquid outlet outflow, therefore can take the most heat in the motor out of, reduce the temperature rise of motor, make the motor high -ef
