Provided is system and method for terminating stator windings to provide a fast, reliable, and convenient connection system. A U-shaped intermediary connection piece comprising individual pieces with cable exits is provided. Stator windings are attached to the individual pieces and the stator and connection piece are encapsulated with resin. The individual pieces are eliminated, thereby electrically isolating the cable exits.

1. A method of terminating the stator windings of an electric motor, comprising the steps of: providing an intermediary connection piece generally configured in an inverted U-shape having a top part and opposing legs extending from opposite edges of said top part, the intermediary connection piece comprising:“n” individual pieces integrally formed with, and joined together by, “n−1” back parts, wherein n>1;a cable exit located on a top part of each of said “n” pieces and adjacent at least one of said “n−1” back parts; and“n−1” cuts through each of said opposing legs between said “n” pieces of the intermediary connection piece and adjacent said “n−1” back parts;connecting the windings of the stator to each of the cable exits of the intermediary connection piece;encapsulating the intermediary connection piece and the stator with resin;eliminating said “n−1” back parts thereby electrically isolating each cable exit; andconnecting the cable exit of each individual piece to a cable. 2. The method of claim 1 wherein eliminating the “n−1” back parts comprises n−1 machining operations. 3. A method of terminating the stator windings of an electric motor, comprising the steps of; providing an intermediary connection piece generally configured in an inverted U-shape having a top part and opposing legs extending from opposite edges of said top part, the intermediary connection piece comprising:“n” individual pieces integrally formed with, and joined together by, “n−1” back parts, wherein n>1;a cable exit located on the top part of each of said “n” pieces and adjacent at least one of said “n−1” back parts; and“n−1” cuts through each of said opposing legs between and partially through said top part of the intermediary connection piece and adjacent said “n−1” back parts;connecting the windings of a stator to each of he said pieces of the intermediary connection piece;encapsulating the intermediary connection piece and the stator with resin;eliminating said “n−1” back parts by cutting the top surface of the intermediary connection piece thereby electrically isolating each cable exit; andconnecting the cable exit of each individual piece to a cable. 4. The method of claim 3, wherein eliminating the “n−1” back parts comprises a single machining operation.
