Patent ID: 11271446

Abstract:
One or a plurality of embodiments of the present application provide a winding method for a stator winding. The method comprises positioning a first wire in a first direction according to a first rule, wherein the first rule is continuously positioning the first wire from a first layer in the first direction at a spacing of R slots in a layer number ascending manner until passing through an Mth layer; in the Mth layer, subjecting the first wire to pass a first same-layer transition and pass through a next slot having a spacing of R; positioning the first wire in a second direction according to a second rule, wherein the second rule comprises positioning the first wire at the spacing of R slots in a layer number descending manner until passing through the first layer; and in the first layer, subjecting the first wire to pass a second same-layer transition and pass through a next slot having the spacing of R, wherein the first wire advances in the same direction in the first same-layer transition and the second same-layer transition; and advancing the first wire by repeating following the first rule, passing the first same-layer transition, following the second rule, and passing the second same-layer transition until the first wire fills up the M layers of the stator without crossing itself, where M is a total number of layers of the first wire in stator slots.
