Low-magnetic-leakage motor rotor iron core

The utility model discloses a rotor core of a low-flux leakage motor. The rotor core comprises a plurality of overlapped rotor punching sheets, the rotor punching sheet comprises a middle annular part and tooth-shaped parts which are uniformly distributed on the periphery of the annular part; the tooth-shaped part comprises a plurality of first tooth sheets and a plurality of second tooth sheets; the first tooth pieces and the second tooth pieces are distributed in a staggered mode, and the first tooth pieces are connected with the annular part. The adjacent rotor punching sheets are distributed in a staggered manner at a certain angle, and the first tooth sheets of the rotor punching sheets are overlapped with the second tooth sheets of the adjacent rotor punching sheets. The first tooth piece and the second tooth piece are consistent in structure, the first tooth piece is connected with the annular part, and the second tooth piece is not connected with the annular part; compared with a traditional structure
