In the age of energy efficiency, engineers are often excited about the potential cost savings associated with variable-frequency drives (VFDs) and their ability to operate motors to match demand loads ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

Inverters used to control a motor’s speed or torque — also known as variable frequency drives (VFDs) or adjustable speed drives — can induce unwanted motor shaft voltages that cause premature motor ...
