Change is in the air: Tony Clark, of ebm-papst UK, looks at developments in EC fans for fan coils

摘要

Continued research and development by ebm-papst of its product ranges now means a wide range of traditional AC fans can be directly interchanged with an electronically commutated (EC) alternative. Not only does this mean more efficient motors but also advantages such as infinitely variable speed control, offering further energy savings, virtually no motor noise and removing the need for external control gear such as transformers or frequency inverters.
