Abstract
The utility model discloses an oil -cooled motor, including the casing, be equipped with stator subassembly in the casing, stator subassembly includes stator core, be equipped with stator winding in stator core, with still be equipped with oil guide piece in one side of stator core, and oil guide piece is connected intercommunication through the connecting pipe of being equipped with with the oil inlet pipe of being equipped with on the casing, stator core is still equipped with oil injection subassembly in the side away from oil guide piece, oil injection subassembly is connected intercommunication through the oil inlet oil channel of being equipped with with oil guide piece, oil injection subassembly includes first stator sheet and third stator sheet, be equipped with oil -passing area on first stator sheet, with still be equipped with nozzle on third stator sheet, wherein, the oil -passing area of oil -passing area is greater than the oil -passing area of nozzle, so that makes the cooling oil spouts before, and oil -passing area plays the role of steady pressure to oil liquid, prolongs the residence time of oil liquid, in the stable cooling oil pressure with the oil liquid carries away more heat energy in order to the cooling effect of this motor is improved.
