Quality Digest Bio Operations Marposs Offers Optical Inspection Systems for Stator Hairpins For workshop or lab environments Published: Monday, July 18, 2022 - 12:00 Comment Rss Send Article (Must Login) Print Author Archive (Marposs: Auburn Hills, MI) -- Marposs, a world leader in measurement, inspection, and test technologies, has announced a noncontact measuring system for performing dimensional verification of hairpins used in stator windings. Through optical inspection using three proprietary high-resolution cameras with telecentric optics, this system measures the head, tail, and roof of the hairpin with the goal of keeping lengths, widths, and twisting under control. This helps to avoid problems during rotor assembly, such as preventing damage to the insulation paper inside the rotor slots. The challenge is producing single hairpins so they properly fit the stator grooves. This is complicated by the fact that hairpins are made of thin copper bar, and therefore inherently weak. Traditional contact systems, or use of reference profile masks/jigs, can easily deform the intended shape. The Marposs noncontact system works by positioning the hairpin on tempered glass with reference points for pin placement. The measurement cycle is then initiated by acquiring three images in sequence, one image for each camera. The processing software identifies the pivotal points of the part, enabling reconstruction of the required dimensions and ensuring accuracy. The entire measurement cycle is accomplished in only 5 seconds. The system is designed for operation in the workshop or lab environment, and provides the flexibility to measure a variety of parts. It can be provided as a manual-loaded test bench or designed for integration into an automated production line for 100 percent product inspection. Optional offerings to complement the optical hairpin inspection system include Marposs SPC software for statistic elaboration and data transfer, and a station for gaging the stripped area of the hairpin.
