  • Patent number: 10411536
    Abstract: An electric motor rotor (100) and an electric motor having the same are provided. The electric motor rotor (100) includes a rotor body (1) provided with a rotor bore (11) and a plurality of magnetic steel slots (12) surrounding the rotor bore (11), in which an outer contour of the rotor body (1) includes a plurality of concentric arc segments (101) in concentric with the rotor bore (11) and a plurality of connecting line segments (102) connecting adjacent concentric arc segments (101), and the connecting line segment (102) includes at least one straight line segment (1021), in which an included angle ? between a central normal line of each straight line segment (1021) and a connecting line between a midpoint of the straight line segment (1021) and a center of the rotor bore (11) satisfies 0°???20°; and a plurality of magnetic steel bars (2).
