The utility model discloses a natural cooling motor that dispels heat for electric motor car, stator winding stretch out the outer extension of stator core in built -in portion and the both ends in locating the stator core mounting groove, and stator winding's extension overcoat is equipped with the heat -conducting cylinder coaxial with shell body of the machine shell, is equipped with the insulating layer between heat -conducting cylinder inner wall and stator winding's the extension, heat -conducting cylinder outer wall and the laminating of shell body of the machine shell inner wall. The direct conduction by the heat -conducting cylinder of heat that stator winding's extension copper loss sent is distributed away for the casing, the problem of the thermal closely conduction path of motor winding overhang copper loss is solved, the motor temperature rise reduces, solved that driving motor is removing under fan blade forced air -cooling or the water -cooled condition for the trolley -bus, the problem of des
