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.

Abstract: A stator includes a stator core and a stator winding. An inner wall of the stator core is provided with M winding slots, the M winding slots are uniformly disposed in a circumferential direction of the inner wall of the stator core. The stator winding includes flat wire conductors inserted in the winding slots, N layers of flat wire conductors are disposed in any one of the winding slots, and phase units of a first-phase winding, phase units of a second-phase winding, and phase units of a third-phase winding are sequentially and periodically arranged along the inner wall of the stator core. Each phase winding includes P parallel branches. Any one of the parallel branches connects flat wire conductors of M·N/3P layers.
