ECM (Electronically Commutated Motor)
An ECM (Electronically Commutated Motor) is a highly efficient and reliable type of brushless DC motor commonly used in HVAC systems. It operates with variable speed capabilities, allowing it to adjust airflow or water flow to match the system’s needs more precisely. These motors are often found in high-quality furnaces, air handlers, and boiler pumps. By reducing energy consumption compared to traditional motors, ECMs help lower utility costs while also providing better temperature and humidity control, improving overall comfort. They may also be referred to by terms such as variable speed, ECM-PWM, X-13, or variable frequency drive.
