Abstract
The utility model discloses a stator lamination of an outer rotor motor, which comprises a stator lamination body (1) and a central hole (2) arranged in the middle of the stator lamination body (1). The outer side of the stator lamination body (1) is provided with a plurality of teeth (3) and a tooth groove (4) consisting of a first tooth groove (41) and a second tooth groove (42); the depth H1 of the first tooth groove (41) is larger than that H2 of the second tooth groove (42); and the area S1 of the first tooth groove (41) is equal to that S2 of the second tooth groove (42). By changing the structure of the tooth groove, a stator winding cannot block the tooth groove, difficulty in winding technique is reduced, and the full rate space of a stator groove is increased so that the requirements of wider products for performances are met.
