Abstract: This application provides an oil-cooled motor, a powertrain, and a vehicle. The oil-cooled motor includes a rotating shaft and a first rotor iron core and a second rotor iron core that are sleeved on the rotating shaft and are adjacent to each other. A rotating shaft oil channel configured to communicate with a cooling system is disposed in the rotating shaft. M first oil channels that penetrate through two end faces of the first rotor iron core are disposed in the first rotor iron core. N second oil channels are disposed in the second rotor iron core. According to the oil-cooled motor provided in this application, a contact area between cooling oil and an interior of a rotor can be increased without affecting structural strength and magnetic conductivity of the rotor, so that cooling effect is improved.
