Flexible stator bars

摘要

A flexible stator bar (10) generally includes a stranded conductor (12) having a rectangular shaped cross sectional profile, wherein the stranded conductor (12) comprises a plurality of wires having a gauge dimension effective to impart flexibility; and a thermoplastic elastomeric insulating material (14) disposed about the stranded conductor (12). Also disclosed herein are processes for fabricating the flexible stator bar (10), which generally comprises depositing a thermoplastic elastomeric insulating material (14) onto the flexible stranded conductor (12), which can be flexibly oriented into a desired position, thereby improving dimensional control relative to Roebel-type stator bars. The insulated flexible stranded conductor (12, 14) may then be coated with a B-stage epoxy or the like and cured to form the final shape after assembly within the desired electrical machine application.
