The increasing demand for compact and high-performance electric motors for the automotive industry, poses the problem of motors with high specific energy and reduced overall dimensions. The problem has been solved by several car manufacturers, using stator winding made by hairpin.
The most important challenge is to realize the single hairpins so that they can best fill the stator grooves. This implies the need to precisely control the dimensions of these light and deformable components. Using a non-contact system, the actual measurement of the component can be obtained without any distortion introduced by touch probe gauging systems or reference jigs.
