| Zusammenfassung: | The invention relates to a rotor iron core structure and a motor. The rotor iron core structure comprises an iron core body and magnetic steel. The iron core body comprises a plurality of first magnetic steel grooves arranged along an outer arc of the iron core body, second magnetic steel grooves arranged along the radial direction of the iron core body and located at two sides of each first magnetic steel groove, third magnetic steel grooves connected with each second magnetic steel groove and parallel to the first magnetic steel grooves, and air grooves connected with each third magnetic steel groove and extending towards the inner arc line of the iron core body. The magnetic steel comprises first outer magnetic steel arranged in the plurality of first magnetic steel grooves and extending along the first magnetic steel grooves, second outer magnetic steel arranged in the plurality of second magnetic steel grooves and extending along the second magnetic steel grooves, and inner magnetic steel arranged in the |
