To increase blower speed, slightly loosen the setscrew that holds the pulley to the driveshaft. ECM motors are programmed to operate at 20 - 35% of their normal airflow (depending on the manufacturer) when there is no call for heating or cooling, which gives constant circulation without operating at high speed. Disconnect PL13 and plug it into the ECM Motor Simulator 3. • ECMs used with furnace fans are optimized to provide constant air volume should the external static pressure change for some reason. Most ECM pumps on the market today . controls, which provides the ability to increase or decrease the speed of the motor . A variable-speed furnace includes a type of blower motor called an electronically commutated motor (ECM). But ECM motors are made of variable speed. BLDC stands for Brushless Direct Current motor: a BLDC motor may be the same as an EC motor, but it is more often used to refer to an electronically controlled motor which uses a DC power supply.
