Surface-mounted brushless motor rotor and motor

The invention relates to a surface-mounted brushless motor rotor and a motor. The surface-mounted brushless motor rotor comprises a rotor core and a plurality of rotor punching sheet groups; each rotor punching sheet group comprises a plurality of stacked arc-shaped magnets, and the contour shapes of the arc-shaped magnets are symmetrical along a geometric central axis parallel to the radial direction of the rotor core; the outline shape of the arc-shaped magnet comprises an inner edge, an outer edge and a pair of side edges, and the included angle between the side edges is 52-84 degrees; theouter edge comprises a middle straight line section, a cambered surface section and an inclined section; the cambered surface section and the inner edge are concentric; and an included angle between the inclined section and the middle straight line section is 25-35 degrees. According to the surface-mounted brushless motor rotor and the motor provided by the invention, the magnetic flux waveform inthe motor is adjusted by
