AUBURN HILLS, MI—Marposs Corp., a leading supplier of measurement, inspection and test equipment, has acquired e.d.c. srl (Electrical Dynamic Co.). The Milan, Italy-based company specializes in functional testing systems for electric motors and their components.

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. Therefore, 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, because it does not require a shielding structure around the testing area.

With this acquisition, Marposs offers a complete range of equipment dedicated to the functional testing and end-of-line testing of any type of electric motor, including in-line and off-line applications, as well as lab analysis.
