Today’s cars have lots of electric motors. Indeed, one would be hard-pressed to find a late-model car with less than a dozen electric motors. Some can easily have more than 40 electric motors—and that’s not including electric vehicles.
Ensuring the safety and performance of all those electric motors is among the businesses of Marposs Corp., a manufacturer of measurement, inspection and test technologies. The company recently introduced the e.d.c. AST320/W, an automated system for testing the windings, coils and stators of electric motors in production environments. The system integrates the company’s e.d.c partial discharge measurement technology, based on capacitor coupling technology, for both AC high pot and surge tests.
