Motor rotor structure and motor

A motor rotor structure comprising:

• a rotor iron core comprising a plurality of rotor sections arranged along an axial direction;
• and
• a plurality of magnetic tile grooves uniformly distributed on a circumference of each rotor section;
• wherein magnetic tile grooves on adjacent ones of the plurality of rotor sections are circumferentially offset from one another at a joint surface between the adjacent rotor sections;
• wherein the magnetic tile grooves of the adjacent rotor sections are staggered at an angle of 0.5° to 7°;
• wherein an outer wall of each rotor section is uniformly formed with rotor skewing;
• and
• wherein a first connection line between a midpoint of a first magnetic tile groove on an end face of the rotor section and a center of the end face of the rotor section, and a second connection line between a midpoint of a bottom edge of the rotor skewing on a same end face of the rotor section and the center of the end face of the rotor section have an included angle of 0° to 1°.
