Variable Frequency Drive Testing


Bradleys offers services for facilities that require maintenance and modifications of low-voltage and medium-voltage Variable Frequency Drives (VFD).

Variable-frequency drives are also known as adjustable-speed drives (ASD). A VFD controls the rotational speed of an alternating current (AC) electric motor by adjusting both the voltage and frequency of the electrical power supplied to the motor. Servicing of Variable Frequency Drives compliments Bradleys’ motor testing and maintenance services. Our VFD engineers provide expertise in diagnosing, troubleshooting, repairing and debugging drive systems.

Your VFD (ASD) systems can be tested through numerous setup configurations. Input voltages up to 13KV are available. System power can be monitored to determine entire system efficiencies at multiple load points. Limited overspeed testing is possibl

“Great Job on the RCFA (Root Cause Failure Analysis)! Arguably the best I have ever seen.”
