First, they provide more efficient airflow.
Is an ECM motor worth it?ĮCM motors are expected to keep homeowners more comfortable, too. They function using a built-in inverter and a magnet rotor, and as a result, can achieve greater efficiency in air-flow systems than some kinds of AC motors. They are also called DC fan motors, EEM fan motors, and variable speed fan motors. What is ECM fan?ĮCMs are a type of DC motor.
In the simplest terms, an ECM motor lowers the total electrical consumption of an AC or furnace and helps to maintain proper air flow through the system. The letters ECM stand for electronically commutated motor, which might sound a bit complex to understand. Since cfm, rpm and torque are all related, the basic prinicples are the same. There are three types of ECM motors: constant cfm, constant rpm, and constant torque. How can I tell if my blower motor is bad?ĮCM stands for an “electronically commutated motor” which basically means a motor that uses electronic controls to vary its speed.Does the ECM control the air conditioner?.What is the difference between a PSC and ECM motor?.
