1. A method of manufacturing a stator for a washing machine, the method comprising:
forming a plurality of stator segments, each stator segment including (i) a yoke section, (ii) a tooth body extending outwardly from the yoke section to an end, and (iii) a shoe at the end of the tooth body, forming a polymeric casing on each stator segment before engaging the yoke sections to form an annular yoke, each polymeric casing extending over only the tooth body and the shoe of the stator segment such that the yoke section of the stator segment is devoid of polymeric material, wherein forming the polymeric casing includes: (i) overmolding a first number of stator segments of the plurality of stator segments with polymeric material to form a first chain of stator segments having a pin formed at a first shoe of the first chain, and (ii) overmolding a second number of stator segments of the plurality of stator segments with polymeric material to form a second chain of stator segments having a notch formed at a last shoe of the second chain, each stator segment of the first chain and the second chain being connected by a polymeric bridge, connecting the first shoe of the first chain with the last shoe of the second chain by positioning the pin of the first chain in the notch of the second chain to form a polymeric bridge between the first shoe of the first chain and the last shoe of the second chain before engaging the yoke sections of the stator segments, engaging the yoke sections of the stator segments to form an annular yoke, and forming a central shell on the annular yoke, the central shell including a plurality of bores for mounting the stator, wherein a polymeric bridge extends between adjacent polymeric casings and connects the shoes of adjacent stator segments. |
