Abstract
A radial flux motor, a powertrain, and a vehicle. The radial flux motor includes a rotor and a motor shaft. The rotor includes a plurality of magnetic steel slots and a plurality of magnetic steels. The magnetic steel slot penetrates through the rotor. Each magnetic steel slot is configured to accommodate one or more magnetic steels. A surface that is of at least one magnetic steel and that is spaced from a slot wall of the magnetic steel slot includes a plurality of primary grooves. The plurality of primary grooves are sequentially arranged at intervals in a length direction of the magnetic steel. A groove cutting position is selected based on eddy current loss density distribution of the magnetic steel, so that an eddy current loss of the magnetic steel in the radial flux motor can be effectively reduced.
