Air Conditioner Squirrel Cage Blower | HVAC blower motors move the air through the system. The blower motor is sized based on the amount of air flow necessary for the system. This blower motor is the supply fan for the supply air in a large commercial York AHU. An AC and heating forced air system is sized based on load. The load factors include heat loss and heat gain, number of people in the building, types of rooms served, factoring in heat produced by equipment such as computers and other heat producing equipment.

Electric Motors Basics - The HVAC industry depends heavily on the electric motor. Furthermore, the electric motor is the primary component that powers blowers to move air. Additionally, electric motors drive compressors to compress refrigerants. Lastly, the electric motor powers a pump to move water for chilled water and hot water applications, and fuel oil.
Additionally, the electric motor is an integral part of all HVAC systems, and many HVAC applications would be impossible to implement without the old electric motor. (more…)
