Abstract
An insulation member for use with a stator assembly is provided. The insulation member includes a body and a cuff. The body includes a first end and an opposite second end, at least one tooth portion, and at least one yoke portion that extends from the at least one tooth portion. The cuff is formed from at least one of the first end and the second end of the body and extends along at least one of the at least one tooth portion and at least one yoke portion.
Claims16
A stator assembly including a plurality of stator segments, the stator assembly comprising:
- a core comprising a plurality of teeth and at least one end face;
- an insulation member positioned between adjacent teeth of said core, said insulation member comprising:
- a body including a first end and an opposite second end, said body comprising at least one tooth portion, a first yoke portion that extends from said at least one tooth portion, a second yoke portion, and a connection portion extending between said first and second yoke portions;
- and
- a cuff formed from at least one of the first end and the second end of said body, said cuff extending along at least one of said at least one tooth portion and said at least one yoke portion, wherein said cuff comprises a flap folded over said body defining a bent portion of said cuff, the bent portion extending continuously along said at least one tooth portion, said first and second yoke portions, and said connection portion, and wherein said insulation member is positioned such that a tip of said flap is spaced a distance from said at least one end face;
- and
- an end cap coupled to said at least one end face, wherein at least a portion of said end cap is positioned in the spaced distance between said at least one end face and said tip of said flap;
- and
- a wire wound about at least one of said plurality of teeth such that said insulation member is positioned between said core tooth and said wire.
A method of assembling a stator assembly including a plurality of stator segments, each stator segment including at least a portion of a core, at least a portion of an end cap, and at least a portion of an insulation member, wherein the core includes a tooth having at least one end face, the insulation member including a body having a first end and an opposite second end, at least one tooth portion, a first yoke portion that extends from the at least one tooth portion, a second yoke portion, and a connection portion extending between the first and second yoke portions, said method comprising:
- forming a cuff from the insulation member along at least one of the tooth portion and the at least one yoke portion, wherein forming the cuff includes folding a flap over the body defining a bent portion of the cuff, the bent portion extending continuously along the at least one tooth portion, the first and second yoke portions, and the connection portion;
- positioning the at least one insulation member such that a tip of the flap is spaced from the at least one end face, and such that the portion of the end cap is positioned between the at least one end face and the tip of the flap;
- and
- winding wire about the core tooth such that the at least one tooth portion of the insulation member is positioned between the core tooth and the wire.
