Variable Speed Furnace Fan Motor

Variable speed fan motor technology variable speed technology can also apply to the type of blower motor located in the air handler or gas furnace.

Variable speed furnace fan motor.

Variable speed furnace motor a variable speed blower motor runs at different speeds to precisely control the flow of heated air throughout your home. Running the heating system s fan continuously allows the furnace s blower motor to continue air circulation even when heating is not required. It constantly monitors the data coming from your heating and cooling system and automatically adjusts to meet your comfort needs. Ecm s are dc motors that function using a built in inverter and a magnet rotor and as a result are able to achieve greater efficiency than most ac motors.

Connected to fan blades it moves air through your ductwork and into the different rooms of your home. In addition to better energy efficiency and temperature control variable speed furnaces deliver better indoor air quality as a result of varying blower motor speed. It s an electronically commutated motor or ecm. Plus a variable speed motor gradually ramps up to full speed eliminating the sudden noisy blast of a standard furnace motors.

The term variable speed actually refers to the blower motor inside the furnace or air handler. Unlike single speed motors that run at full capacity and then cycle off a variable speed motor can operate at high speeds low speeds or anywhere in between ramping up and down like a dimmer switch.
