New Rosenberg 500-Watt EC Motors Provide More Airflow, Greater Efficiency

Rosenberg's redesigned and improved GD84 500-Watt, 230-Volt single phase EC motors run cooler and more efficiently, while increasing airflow. They are available now on Rosenberg axial and backward curved fans for HVAC and equipment cooling applications.

The new UL-recognized motors increase airflow and pressure output by 2% to 5% depending on the fan model.

Features of the GD84 motor include higher efficiency electronics that offer a significant decrease in nominal current.  An improved housing design features an integrated, highly efficient heat sink for improved thermal management.

Standard input voltage is 200 to 277-Volt single phase in 50-60 Hz frequency. In addition to standard products, Rosenberg builds fans and motors to specific customer needs such as special finishes, voltages or frequencies.

Rosenberg’s electronically commutated (EC) motors provide easy speed control, long life expectancy and low operating costs. They are CE-approved and meet ErP 2015 requirements.
