An ECM motor is controlled by a microprocessor, the key component that makes them able to provide higher efficiency. The microprocessor calculates the motor’s speed and torque to regulate the airflow. The rotations per minute of the motor will either ramp up or ramp down to keep the air fl...
An electronically commutated motor is a three-phase, brushless DC motor. It comprises three major components: a circuit board, an electronic control module, and a three-phase motor with a permanent magnet rotor, as shown in Figure 1. The module and motor make up the actual ECM. The circuit...
The term "Variable Speed" actually refers to the blower motor inside the furnace or air handler. It's an Electronically commutated motor, or (ECM). 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...
HVAC systems have many different components inside the condenser and furnace that work together to keep your home comfortable year-round. One of those components is the blower motor or indoor blower motor which is essential to both theheatingand cooling process. In this article we discuss what it...
Where you live in the U.S. determines which air conditioners and heat pumps you can shop for — in a good way!
Electronically Commutated Motor (ECM) In the last two decades, several electric motor manufacturers, including Genteq and Emerson introduced fractional horsepower variable speed ECMs touting a wide range of benefits such as: • Incorporating a separate motor that is wound like an industrial three-pha...
