Abstract:
1. A washing machine having a motor for providing rotative driving force required for washing, a stator of the motor comprising: a stator core of a stack of bases each with a plurality of poles; an insulator having an upper insulator and a lower insulator fastened to the stator core; a plurality of fastening portions each having a fastening hole for fastening the stator; a plurality of connection portions each having a plurality of vertical ribs for connecting the insulator to each of the fastening portions; and a horizontal web that connects the plurality of vertical ribs, the horizontal web is formed on a plane perpendicular to the plurality of vertical ribs, wherein the insulator, the fastening portions, and the connection portions are injection molded as one unit, with the stator core inserted thereto, and wherein each of the connection portions includes a center vertical rib that connects each of the fastening portions to the insulator with a shortest distance from among the corresponding plurality of ribs for the particular connection portion, the center vertical rib defining a center line of extension and the center vertical rib is arranged between a first line of extension of a first pole nearest to the center vertical rib and a second line of extension of a second pole nearest to the center vertical rib, wherein the first line of extension is immediately adjacent the center line of extension, and the second line of extension is immediately adjacent the center line of extension, and wherein no poles are provided along the center line of extension.
