During prototype development, NORD Drivesystems - the drive manufacturer conducts comprehensive tests with frequency inverters and motor starters in an EMC cabin at the company's HQ location in Germany. These documented tests significantly accelerate the CE certification process. Electromagnetic compatibility or EMC testing examines two different aspects: on the one hand, drive electronics are checked for their own emission of electromagnetic energy, which must not exceed specific limit values.
On the other hand, these test objects must also be confirmed to be immune to interference from other emission sources. Using the in-house EMC cabin, NORD is able to detect potential problem sources at an early stage and efficiently resolve any such issues well in time. The latest product family of field distribution systems, including all-new size 2 inverters (5.5 and 7.5 kW), was recently classified using this testing facility, and development of another product series is already in full swing as well.
NORD is able to examine the EMC behavior of electronic drives on their own as well as in combination with a motor, including specific setups as requested by a customer. This enables checks of circuits and installations, which helps speed up subsequent inspections by accredited laboratories. The drive technology manufacturer also runs climate unit tests to ascertain resistance to cold, heat, moisture, and temperature changes, and can perform temperature monitoring to ensure that products stay within their designated operating temperature range.
