This application provides an oil-cooled motor rotor in a groove, a motor, a powertrain, and an electric vehicle. The motor rotor includes a motor shaft, at least one end plate, at least one rotor iron core, and a plurality of magnetic steels. The one rotor iron core includes a plurality of magnetic steel grooves. Each magnetic steel groove is configured to fasten at least one magnetic steel. At least one magnetic steel groove includes a plurality of bumps. The bump enables the magnetic steel groove to form a gap with the magnetic steel. The gap is configured to form an internal flow channel of the one rotor iron core and is configured to communicate with an oil groove of the one end plate. Cooling oil is in direct contact with the magnetic steel to cool the magnetic steel, thereby improving cooling efficiency of the rotor iron core.
