Marposs Adds Electric Motor Testing to Its Offerings With e.d.c. srl Acquisition

Marposs can now offer complete range of solutions for functional testing and end-of-line testing of any type of electric motor

(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.

With this acquisition, Marposs offers a complete range of solutions 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. These systems include:
• Stator testing for production lines (wound or hairpin) including partial discharge measurement
• Rotor testing for permanent magnet, squirrel cage, and wound rotors
• Automatic end-of-line testing motor testing (load/no-load) for production
• Dynamometer testing for motor load and life-cycle simulation in the laboratory
• Advanced windings and insulation quality analysis for the laboratory

Marposs, founded in 1952, has distinguished itself by supplying advanced solutions that improve quality and productivity while reducing manufacturing costs through technologies such as process control, machine tool monitoring, and precision gauging, as well as leak testing and automated assembly and control lines. A long-time key supplier to the automotive and aerospace markets, Marposs’ growth strategy includes the acquisition of high-quality companies that offer innovative products complementary to its portfolio, enabling penetration into new market sectors. The group currently has more than 3,700 employees worldwide and is present in 25 countries through more than 80 offices.

Complete information about Marposs solutions can be found at www.marposs.com, by calling (248) 370-0404, or by emailing marposs@us.marposs.com.

Marposs has added functional electric motor testing to its portfolio with the acquisition of e.d.c.srl.
