Abstract: This application describes examples of a rotor disk and a manufacturing method thereof, a rotor structure, a disk motor, and an electric vehicle. In one example, the rotor disk includes a rotor iron core. The rotor iron core is provided with a plurality of groups of accommodating cavities at intervals in a circumferential direction of the rotor iron core. Each group of accommodating cavities includes a first accommodating cavity and a second accommodating cavity. The first accommodating cavity and the second accommodating cavity are provided in a radial direction of the rotor iron core and are in communication with each other. The first accommodating cavity and the second accommodating cavity are configured to respectively accommodate a first unit portion and a second unit portion of a first magnet.

Abstract: A motor and a vehicle. The motor includes a stator iron core and a flat wire winding structure. Each stator slot has n layers of the flat wire winding structure. Each phase of the flat wire winding structure includes a first part and a second part, the first part occupies a layers in the stator slot, and the second part occupies b layers in the stator slot, and a≠b. In addition, in each pole of each phase of the flat wire winding structure, a stator slot wound with the first part and a stator slot wound with the second part are staggered by y1 slots. The pitch y is less than a pole pitch y0. In this way, the flat wire winding structure is a short-pitch winding, and further, when the motor runs, good torque fluctuation suppression effect is achieved.
