Jerry S. Wang is a product engineer at Eaton who manages and markets medium-voltage control products. He has held engineering positions supporting medium-voltage controls and drives, electrical network protectors as well as medical products. He has a bachelor’s degree in engineering from North Carolina State University.
Employing AFDs for motor control, users can match the power used with system requirements and reduce overall energy consumption and associated costs. In other words, applications can use only the power needed.
Multiple motors can be controlled by a single-drive synchronous transfer system. Key synchronous transfer system characteristics can further save space, reduce costs and improve reliability. A double-bus system design, set for the utility 60-Hz power, can further simplify and reduce installation costs. With a high power density design, both the bypass contactor and motor select contactor can be stacked and equipped in the same physical structure to save space.
