A Wisconsin based manufacturing company, Bradley Corporation, was losing compressor motor bearings almost every year on their main compressor units. The Atlas Copco compressors, with 243HP Siemens motors, were failing due to induced shaft currents generated by the VFDs (GA180 VSD-FF) that control each compressor motor.
