(Marposs: Auburn Hills, MI) -- Marposs, a world leader in measurement, inspection, and test technologies has announced the acquisition of e.d.c. srl (Electrical Dynamic Company), an Italian company based in Milan and a world leader in functional testing systems for electric motors and their components. Electrical Dynamic Company, founded in 1964, has more than 20,000 testing systems installed worldwide including 8,000 dedicated to partial discharge measurement.

Unlike standard electrical testing, the capacitor coupling technology used by e.d.c. is unique to its systems. It makes the instrument insensitive to electromagnetic noise and, therefore, a better solution for use in the production environment where it can identify 100 percent of defects, including latent ones that could generate e-motors failure after short operating times. This testing becomes even more critical for electric motors powered by inverters, such as those used in electric vehicles where there is an inevitable excess of voltage, causing stress to the motor windings. The e.d.c. solution is also cost-effective as it does not require a shielding structure around the testing area.
