Original Abstract Submitted
This application relates to the field of motor technologies, and provides a motor rotor, a drive motor, and an electric vehicle. In the motor rotor, a rotor core with at least two protruding components is designed. At least two magnetic steels and at least two sheets are disposed in grooves between the at least two protruding components and then coupled to the rotor core with a rotor pressing plate. In addition, one SMC sheet is stacked on each of the magnetic steels, so that an eddy current loss of a permanent magnet can be effectively reduced. Each of the magnetic steels is disposed in a groove between protruding components, and the SMC sheet is added, so that a saliency ratio is increased, a reluctance torque ratio is increased, and a quantity of magnetic steels for use is reduced.
