A.O. Smith ECM Variable Speed Fan Motors
|
 |
A.O. Smith ECM allows original equipment designers to use features that go beyond typical permanent split capacitor motors. The motor can be designed for constant torque, constant CFM, or constant speed. System performance in heating, cooling, and refrigeration equipment can be improved by utilizing speed control at various operating conditions designed for constant airflow, lower noise levels, better humidity control, and improved air quality. A.O. Smith ECM motors are agency approved.

MOTOR CONTROL PROGRAMMABILITY
Since each horsepower rating has some "stretch" in output, fewer motors are needed in an equipment product line. To match the various fan system needs, the motor can be programmed for direction of rotation, ramp-up/down rates, speed matching to static pressure, and communication to other devices, among many other functions.
APPLICATIONS
The 48 frame A.O. Smith ECM is focused on the indoor air handler of furnaces, heat pumps, and air conditioners. Single and variable-capacity gas and electric furnaces, energy recovery equipment, and commercial fans for comfort conditioning are natural applications. Other models are available for the outdoor fan application.
SIMPLE INSTALLATION AND SERVICING
Original equipment manufacturers will appreciate the ease of programming. The motor physically installs as easy as a PSC motor. The software settings can be pre-programmed or line programmed with a laptop computer. Existing load characteristics can easily be downloaded in the field. Should the electronics need servicing, the control module can be easily replaced by an HVAC/R field service technician. |
