Variable Speed Furnace Blower

It s an electronically commutated motor or ecm.

Variable speed furnace blower.

Better airflow control has several benefits. The air quality is improved in your home with a variable speed blower. The term variable speed refers to the furnace s indoor blower motor which moves at different speeds to precisely control the flow of heated and cooled air throughout your home. The term variable speed furnace is used to describe furnaces that have a variable speed blower motor.

Variable speed blower motor s. 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. Single speed blower motors function at full power or not at all switching off and on to regulate your indoor temperatures. It provides the precise heat or cooling output your home needs at any given time day or night.

Variable speed furnaces contain an ecm electronically commutated motor blower motor which allows the furnace to operate at higher efficiency levels. The blower motor is effective at removing excess humidity from the air during the cooling season. The term variable speed actually refers to the blower motor inside the furnace or air handler. In the winter a variable speed blower motor may alleviate the cold air blow often associated with single speed furnaces or air handlers.

In contrast variable speed models operate at a range of levels depending on your household s heating needs at the moment in the summer they work to cool your home too. These speeds are used by a contractor to adjust airflow to the proper amount. Variable speed furnaces generally only run at high capacity during the coldest portion of the heating season so they are efficient. A variable speed furnace blower motor is a step above a multi speed blower.

These blower motors are the motors that move air through the ductwork in your home. I t is more like a continuous blowing approach. It can improve the efficiency of your heating system while making your home more comfortable. A variable speed blower motor can operate at various speeds to precisely control the amount of airflow throughout your home.

This n ew technology has an ecm motor with a speed controller. They are dc motors that use a built in inverter and magnet rotor delivering better energy efficiency than furnaces with ac motors.
