Abstract
A stator assembly in which a stack of stator laminations form a stator core. The laminations are shaped to form a plurality of poles projecting radially inwardly with arcuate undercut slots between the poles. The laminations are held together by a plurality of molded tubular insulator members, each comprising male and female sections inserted from opposite directions into the slots and joining together telescopically within the slots. Each end of the tubular member sections have integral flanges which engage the ends of the poles between the slots. The tubular members are split lengthwise and compressed to insert them in the slots. Once inserted, the tubular members expand within the slots to grip the edges of the laminations and hold the stack together and in alignment. The stator coils extend through the tubular members within the slots, the members providing insulation between the coils and the core.
