An electric motor converts electrical energy into mechanical energy. In an HVAC system, motors typically turn the air conditioning fan blade and the furnace blower motor. Newer high efficient motors, such as X13 and ECM motors, have "end caps" that control the motor speeds. These can be removed and replaced separately.
