| description | The present invention discloses a stator lamination with unequal slots for use in three-phase asynchronous motor having low harmonic and unequal turns winding, including a ring-shaped substrate, wherein stator slot groups are radially and uniformly arranged on the inner ring surface of the substrate along the circumference direction of the substrate. The number of stator slots per pole and phase in each stator slot group is three to nine, including at least one large stator slot and at least two small stator slots, wherein the at least one large stator slot is arranged in the middle of the stator slot group, and the two sides of the large stator slot are respectively symmetrically arranged with one or more small stator slots. Or, the number of stator slots per pole and phase in each stator slot group is five to nine, including at least one large stator slot, at least two middle stator slots and at least two small stator slots, wherein the at least one large stator slot is arranged in the middle of the stator slot group, the two sides of the large stator slot are respectively symmetrically arranged with one or more small stator slots, and between the large stator slot and the small stator slot are respectively symmetrically arranged with one or more middle stator slots. |
