A motor rotor, a motor, and an electric vehicle are disclosed. The motor rotor includes an iron core yoke, a spoke plate, and at least two permanent magnets. The at least two permanent magnets are fastened to the iron core yoke and sequentially spaced apart in the circumferential direction. The spoke plate is located between adjacent permanent magnets. A quadrature-axis magnetic circuit is reserved between adjacent permanent magnets, and the spoke plate whose reluctance is less than that of air or the permanent magnet material is disposed on the quadrature-axis magnetic circuit, that is, the spoke plate is disposed between the adjacent permanent magnets. In this way, reluctance of the quadrature-axis magnetic circuit may be reduced, and quadrature-axis inductance may be increased. Accordingly, a reluctance torque is increased, and a torque output capability of the motor is improved.
