Electronically commutated motors are applied to drive the fans in fan powered terminal units for variable airflow applications. Two fan models used to characterize larger commercial variable speed fans were evaluated to determine if they could be applied to model electronically commutated fan/motor combinations used in fan powered terminal units. These models included those by Clark (1985) and Stein and Hydeman (2004). Four manufacturers provided detailed performance data on 36 fan/motor combinations that were used in commercially available series and parallel fan powered terminal units. All of the fan motors were electronically commutated motors with motor sizes ranging from 0.33 to 1 hp (249 to 746 W). The data included airflow, power, and power factors that were measured over a range of static discharge pressure from 0.1 to 0.75 in w.g. (25 to 187 Pa).
